rgl - v1.3.24

• The shapelist3d() function did not handle material names properly (issue #462).
• The markdown package no longer supports rgl, so the change in rgl 1.3.1 to use it has been reverted. This means Pandoc is once again necessary to build the vignettes.
• Links from help pages to vignettes have been repaired and added, using new \HTMLVignette{}{}{} and \HTMLVignetteCRAN{}{}{}{} macros.
• To support those macros, two environment variables are used. VignetteRdPath (default "../html/") should be the lead-in of the URL for the HTML version of an Rd help file referenced from a vignette, and RdVignettePath (default "../doc/") should be the lead-in of the URL for a vignette referenced from an Rd file.
• abclines3d() did not handle multiple colors properly, sometimes causing a crash (issue #476).
• The COPYING.GL2PS file containing the license for the code used in rgl.postscript() has been moved so that it will be installed at the top level of the package.

• Internal code changes to satisfy R CMD check requirements.
• Some memory leaks reported in issue #451 have been fixed.
• The OpenGL "glad" loader has been updated to version 2.0.8.

rgl - v1.3.17

rgl 1.3.17

Bug fix

• The previous fix for rgl.init() introduced a new possible segfault for users who had DISPLAY unset or set to a non-existent server.

rgl - v1.3.16

rgl 1.3.16

Bug fixes

• triangulate() now uses the earcut library from https://github.com/mapbox/earcut.hpp, which should be faster and more reliable than the previous R implementation.
• In cases where the X11 server did not provide sufficient support, rgl.init() could sometimes segfault. That has been fixed, and warning messages have been made more informative.

rgl - v1.3.14

rgl 1.3.14

Minor changes

• rgl.incrementID() has been added.
• An example using log axes has been added to the help page for axes3d().

Bug fixes

• clear3d("all"), calling bg3d() on the root subscene, and some cases of pop3d() involving the background could create a leak of a background object (issue #439). For back compatibility of saved results, these cases still increment the object ID number, but don't actually create a new object.
• rglwidget() displays didn't support objects with smooth = FALSE.

rgl - v1.3.12

rgl 1.3.12

Minor changes

• readSTL() can now read (some) ASCII format STL files.
• The configure script has had minor changes, and autoconf support files have been updated.
• uname is no longer used during startup (PR #435 submitted by Jonathon Love).

Bug fixes

• Background plots did not always appear (issue #421).
• Changing the background resulted in an additional background object instead of replacing the current one.
• Colors weren't handled correctly by writePLY() (issue #425).
• bbox3d() objects ignored the xlen, ylen and zlen settings when rendered using rglwidget() (issue #415).
• In certain cases, the WebGL vignette started with the mouse mode set to "selecting".
• The rglwidget() function gets a new argument fastTransparency which makes WebGL mimic the rgl device when drawing transparent objects. The default value is TRUE unless option rgl.fastTransparency is set to FALSE.
• writeSTL() now writes endsolid, which is required by some apps.

rgl - rgl 1.3.1

Major changes

• sprites3d() now supports plotting different 3D symbols at each location (issue #406).

Minor changes

• ARIA support now declares rgl scenes with role = "img".
• The vignettes in this package now use markdown::html_format, so they no longer require Pandoc (though Pandoc-using output formats like html_document will still be supported).
• Christophe Geuzaine's GL2PS library (used by rgl.postscript()) updated to version 1.4.2, and blending (transparency) has been enabled in formats that support it.
• The Makevars.ucrt file has been changed for compatibility with an upcoming change to Windows Rtools. (Pull request #412 submitted by Tomas Kalibera).

Bug fixes

• The ARIA support caused htmlwidgets::saveWidget() to fail when run in a Shiny session.
• text3d() and mtext3d() did not pass the cex argument to plotmath3d() (pull request #384).
• polygon3d() failed when given exactly 3 points (issue #388).
• snapshot3d() failed on Windows with some versions of webshot2 (issue #391).
• Fixed issues caused by misuse of dev.off() using new function safe.dev.off().
• Fixed issue with warning() call reported by CRAN.
• Smooth shapes were not rendered correctly by rglwidget(). This was especially noticeable for spheres with fov = 0, but was present in other cases as well (issue #401).
• textype = "alpha" was not rendered correctly by rglwidget() (issue #408).
• setUserCallbacks() and related functions failed when the subscene argument was anything other than the root subscene.

rgl - v1.2.1

rgl 1.2.1

Major changes

• Support for non-PNG textures has been added. Currently supported: JPEG files and any other object for which grDevices::as.raster() works, e.g. matrices. (Fixes issue #196.)

Minor changes

• Support for "alt" text has been added to rglwidget(). Full support in R Markdown or knitr requires a knitr update to version 1.42.12 or newer.
• Some of the tests have been relaxed slightly so they shouldn't trigger errors on the M1Mac test platform.
• Internally, the C++ code has dropped the use of the internally defined String type, settling on std::string instead.
• subdivision3d(), clipMesh3d() and related functions now (optionally) record the original faces associated with each new one in a mesh$tags addition to the output.

Bug fixes

• The Makevars.win file was being produced incorrectly on older Windows versions.
• rgl.window2user() did not work correctly when multiple panes were showing. This caused arrow3d() to fail in some panes (issue #354).
• selectpoints3d() had a typo which was revealed by warnings in recent R versions.
• getShaders() was broken in 1.1.3.
• arc3d() can now handle "arcs" that are straight lines along a radius (issue #357).
• Spheres did not show textures correctly (issue #360).
• hover3d() failed to display default labels in R (issue #362).
• shade3d() didn't handle meshes with a mix of triangles and quads properly when meshColor == "faces".
• subdivision3d() and related functions now handle colors properly.
• addNormals() sometimes gave NaN values due to rounding error (issue #372).
• arc3d() sometimes missed plotting the last segment of the arc (issue #369).
• R_NO_REMAP has been defined and header includes have been rearranged to prevent conflict between R internals and C++17 library. (Thanks to Prof. B. D. Ripley and G. Csardi for suggested fixes.)

rgl - v1.1.3

rgl 1.1.3

Major changes

• A new function hover3d() has been added to display "hover hints": labels next to points when the mouse passes near them.
• A new material property "texmode" has been added to control how textures are applied. The default is "modulate", consistent with previous versions. If set to "replace", the texture is displayed without any lighting effects or dependence on the original color of the surface.
• Many of the demos have been moved to a new vignette called demos.
• rgl now uses the glad loader which will eventually allow access to newer OpenGL functions in systems that support them.

Minor changes

• The texenvmap = TRUE material property is now supported in WebGL.
• The method of including shader source code has changed to work around a limitation in Jupyter.
• The default C++ standard is now accepted, rather than requiring C++11. On R versions prior to R 4.2.0 C++11 is still requested.

Bug fixes

• The as.mesh3d.rglId() and as.triangles3d.rglId() methods and the selectpoints3d(), writeOBJ(), writePLY() and writeSTL() functions did not handle indices in the objects they were processing (issue #293).
• Transparent planes were not always drawn properly in WebGL (issue #300).
• view3d() now returns a lowlevel() result so that it will be handled properly in WebGL vignettes with auto printing.
• If transform3d() or rotate3d() changed the orientation of a mesh3d object with normals, the normals ended up with the wrong sign. (Reported by Stephane Laurent.)
• scene3d() (and hence rglwidget()) did not save the normals for unlit objects. When the objects were also indexed, this prevented proper calculation of front and back. This is fixed, and a warning is issued if normals are not provided when needed.
• It was possible to call glVersion before OpenGL was initialized; this resulted in a segfault with the new glad loader, and may have been the cause of some older crashes as well. This has been fixed.
• readOBJ() did not handle comments properly.
• Sprites consisting only of line segments (as used for example by pch3d()) caused rendering to fail in rglwidget() (issue #316).
• Headers have been cleaned up to fix problems identified by Rtools43.

rgl - v1.0.1

Major changes

• The long promised deprecations of the rgl.* functions have happened. Now deprecated: rgl.abclines, rgl.bbox, rgl.bg, rgl.clear, rgl.clipplanes, rgl.close, rgl.light, rgl.lines, rgl.linestrips, rgl.material, rgl.open, rgl.planes, rgl.points, rgl.quads, rgl.select3d, rgl.set, rgl.setAxisCallback, rgl.sprites, rgl.surface, rgl.texts, rgl.triangles, and rgl.viewpoint.
• A vignette "Deprecating the rgl.* interface" has been added.
• Also deprecated: elementId2Prefix, writeWebGL

Minor changes

• Since rgl.material is deprecated and no longer contains the list of material types in its argument list, rgl.material.names and rgl.material.readonly have been added.
  
• Similarly, rgl.par3d.names and rgl.par3d.readonly contain lists of properties that may be set or queried in par3d().
• The flexibility improvements for surface3d() in 0.111.6 were incomplete.
• Argument flip has been added to surface3d() to allow front and back to be switched.

- C++
Published by dmurdoch about 3 years ago

rgl - v0.111.6

Minor changes

• Added a panning example to the help page for setUserCallbacks().
• Replaced all calls to sprintf from C/C++ code with calls to snprintf.
• surface3d and rgl.surface are now more flexible, allowing any of the 3 coordinates to be a vector or matrix as long as at least one is a matrix.
• material3d can now specify an id to query properties for individual objects.
• Since rgl.material is soon to be deprecated and no longer contain the list of material types in its argument list, rgl.material.names and rgl.material.readonly have been added.
  
• Similarly, rgl.par3d.names and rgl.par3d.readonly contain lists of properties that may be set or queried in par3d().
• Made some examples conditional on interactive use to save time on CRAN.

Bug fixes

• Default mouse modes used when a window is opened by an rgl.* call (which is not recommended!) now match the defaults in rgl::r3dDefaults.
• Missing values could cause surface3d() to segfault.
• The C source code for gl2psGetFileFormat missed declaring a prototype.

- C++

rgl - rgl 0.109.6

Minor changes

• rglwidget() displays now act on “pointer” events, not just “mouse” events, so they should be more usable on touch screens and tablets (PR #240).

Bug fixes

• Plotting scene3d() objects didn’t handle suppressed axes properly, drawing the default axis instead (issue #241).
• On some systems using X11, rgl would segfault when the “fixed” font was not found.
• X11 errors could cause R to abort.

rgl - rgl 0.109.2

This is a fairly large update, fixing a lot of bugs and adding a number of new features.

Major changes

• Changes to support glTF animation:
  • Handling of embedding = "modify" for the model matrix has changed. Now the centering step is only done for embedding = "replace". In addition, various bugs have been fixed.
  • If a subscene has no lights defined, the lights from the parent are used.
  • plot.rglscene() now ends with the root subscene as current. It also allows specification of open3d() parameters in a list.
  • The MATn types in Buffer are returned as arrays with dim c(n, n, count).
  • The plot3d.rglscene method now passes ... to open3d().
  • The setUserShaders() function now allows arrays of 4x4 matrices as "uniforms", and allows additional textures to be specified.
• sprites3d() now has the option of rotating = TRUE, to allow 3D sprites to rotate with the scene.
• Added getShaders() function to get shaders used in WebGL.
• Now detects if rgl is running within reprex::reprex() and if so arranges that a screenshot will be included in the output.
• Added default shaders to be used in rglwidget(), rather than constructing them on the fly. This incompatibly affects the use of lights and clipping planes with user shaders: their data is now stored in arrays rather than multiple numbered variables.

Minor changes

• Now that pkgdown 2.0.0 has been released, a number of internal workarounds to support the development version have been removed.
• Added as.mesh3d() methods for "rglsubscene" and "rglscene".
• open3d() now handles useNULL and silent arguments passed in params.
• Controls passed to playwidget() may now include a component specifying HTML dependencies.
• Added rglwidgetClass.readAccessor() method to let other code use the buffering.
• Changed the internal organization of bounding box calculations.
• All functions that produce meshes now accept material properties. Newly modified to do so using the ... argument: cylinder3d(), and getBoundary3d().
• Updated the system requirements and installation instructions.
• Solid bounding box decorations now try harder to display 3 faces (issue #206).
• Now that webshot2 is on CRAN, instructions for installing it from Github have been removed.
• Sometimes webshot2 snapshots are very slow, so the default for the webshot argument to snapshot3d() now depends on the RGL_USE_WEBSHOT environment variable, using TRUE if it is unset. (Reported by Prof. B. D. Ripley.)
• If the Chrome browser is not found, snapshot3d(webshot = TRUE) now issues a warning and reverts to using rgl.snapshot().
• Buffers now use "normalized integers" to store color or texture coordinate values that lie between 0 and 1 when it saves some space.
• At the request of CRAN, the akima package is no longer suggested.

Bug fixes

• as.mesh3d.rglobject() didn't handle objects with indices properly.
• In WebGL, the front vs back calculation sometimes got the wrong result (issue #164).
• pop3d(tag = x) did not always find the objects with tag == x if they were not in the current subscene.
• The default values for front and back in rgl.material and material3d are now "filled", as documented in some places.
• The fog setting wasn't handled properly by bg3d().
• Numerous cases of partial argument matching were fixed (suggestion of Henrik Bengtsson in issue #170.)
• Argument col is accepted as a synonym for color in material3d() and rgl.material().
• planes3d() objects were not displayed consistently in rgl windows and WebGL displays, because the bounding boxes were not computed consistently (issue #169).
• Some initialization wasn't done properly in Shiny apps, so they failed after a redraw (issue #173).
• Buffers are now optional, as they don't work with Shiny scene changes (also issue #173).
• The NULL device would sometimes miscalculate the bounding box.
• selectpoints3d(closest = TRUE) selected too many points when multiple objects were in the scene.
• Clearing nested subscenes could cause a segfault and crash.
• In knitr and rmarkdown, blank plots could be shown when par3d(skipRedraw=TRUE) was set (issue #188).
• Objects drawn with sprites3d() weren't lit correctly in WebGL (issue #189).
• Objects with textures were sometimes drawn more than once, both before the texture loaded and after. This was most noticeable for objects with user textures.
• Axis mode "pretty" got lost when scenes were redrawn.
• Tick labels were sometimes lost in WebGL displays and snapshot3d() results (issue #197).
• The new material properties from 0.107.10 and 0.108.3 were not handled properly by plotmath3d().
• rglMouse() did not set the default value of the drop-down selector properly (issue #213).
• merge.mesh3d(), used by filledContour3d(), didn't handle colors properly (issue #212).
• bg3d(sphere = TRUE) has been fixed (issue #207).
• Textures were not appearing on spheres, and front-back differences weren't being rendered (issue #217).
• When "knitting" within RStudio under R 4.2.0 on Windows, rgl scenes didn't appear (reported by Dieter Menne.) A workaround has been added.
• In rglwidget(), axis labels were not always displayed, and did not move with solid bounding box decorations properly (issue #206).
• On some systems, lines3d() using both missing values and transparency did not draw properly (issue #234, originally reported by Gaspar Jekely).
• The rglShared() example failed when crosstalk was uninstalled.

rgl - rgl 0.107.14

Major changes

• Added expect_known_scene() function to work with testthat.
• Added some testthat tests.
• Prepend a 5th entry to par3d("mouseMode"), corresponding to actions to take when no button is pressed.
• Allowed any of the mouse modes to be applied to the mouse wheel.
• Added the setUserCallbacks() function to allow user-specified mouse callbacks in WebGL code.
• Added Javascript code for support of movable axis labels in bboxdeco objects.
• Most drawing functions can now draw in the margins using new material properties margin and floating, with objects that move as the bounding box changes. See ?mtext3d for details.
• The mtext3d() argument order has changed.
• Added the setAxisCallbacks() function to allow user-specified axis drawing routines.
• Exposed (and generalized) the as.tmesh3d() function.

Minor changes

• The shiny and manipulateWidget packages have been changed from imports that are always loaded to suggested packages that will only be loaded if needed. This will reduce the "footprint" of rgl for users who don't use them.
• The NULL device can now specify par3d("useFreeType") and the result is saved.
• Code to work with pre-1.33 versions of knitr has now been removed.
• Added documentation of Javascript to web page.
• The handling of the RGL_DEBUGGING environment variable has changed: now it must look like TRUE to trigger Javascript debugging mode.
• Argument webshot = TRUE has been added to movie3d (issue #113).
• The assert() macro is now always defined.
• In Windows, the WM_PAINT handler should be more tolerant of code called while painting.
• as.mesh3d.default() can create segments. (Contributed by Michael Sumner.)
• compare_proxy.mesh3d() has been modified to be compatible with both current and upcoming versions of waldo.

Bug fixes

• The bug workaround in 0.105.22 for issue #27 triggered a bug in RStudio, resulting in two RStudio processes showing up when rgl was loaded. The workaround is now skipped when RStudio is detected. Use options(startQuartz = TRUE) in RStudio before loading rgl to run it, or options(startQuartz = FALSE) to suppress it.
• In some cases, snapshots in rmarkdown documents were produced at the wrong size.
• Controls failed to modify sphere colors (e.g. as in example(playwidget), issue #102)

rgl - rgl 0.108.3

Major changes

• Added getBoundary3d() function to extract the boundary edges of a mesh.
• Added material property tag, a string associated with each object. The value is reported by ids3d(tags = TRUE) and may be used to select objects in most functions that use ids, but otherwise is largely ignored by rgl. The tagged3d() function returns information on tags.
• Primitive types (points, lines, segments, triangles, quads) can now accept an indices parameter, similar to the indices in mesh3d objects.
• Added Buffer object, based on glTF design, for holding binary data for rglwidget().

Minor changes

• Allowed for a third coordinate in text3d()'s adj parameter.
• Added support for adj, pos and offset to sprites3d().
• Added support for pos values of 0 (at specified location), 5 (in front of it), and 6 (behind it) in text3d(), sprites3d() and plotmath3d().
• crosstalk is now a Suggested package, rather than a required one.
• The Makevars.ucrt file has been modified with contributions from Tomas Kalibera to work with his winutf8 build of R.
• bgplot3d() no longer pauses for each page when running examples.
• deldir version 1.0-2 is incompatible with rgl. Added the checkDeldir() function to avoid running it.
• shade3d() treated texture coordinates like colors, and duplicated the first one for the whole face when meshColor = "faces" was chosen. Instead, they are now treated like vertex coordinates. (Reported by Michael Sumner in issue #145).
• Corrected the documentation and made the implementations of asHomogeneous(), asEuclidean() etc. more consistent.
• An as.rglscene() generic has been added, though no methods are defined in this package.
• downlit 0.4.0 has been released with support for rgl, so instructions for installing the devel version have been removed.

Bug fixes

• Fixed rendering of text as sprites3d() objects.
• Added --static flag to configure script for FreeType installation. (Suggestion of Simon Urbanek and Prof. Brian Ripley.)
• shade3d(), wire3d() and dots3d() overrode "front" and "back" material settings in mesh objects.
• rglwidget() handling of bounding box decorations had several bugs.
• rgl could not find routines in the DLL on some Windows installs (Issue 148.)
• Some cases where allocations were not protected have been fixed.
