💖 NAME 💖

okay so this is coin400, and it lives in the Coin manual, section 3. it's literally the rundown of everything new in Coin v4.0.0 and bestie, there's a LOT. grab a snack. 🍓

first tho, some lore:

Kongsberg Oil & Gas Technologies AS ended Coin as a commercial product and re-licensed it under the BSD 3-clause license as a service to the user community. iconic behavior honestly. 💅

the build system has been migrated from GNU Autotools to CMake. glow up fr.

✨ the new features, bestie ✨

this is a brief summary of the new features in Coin v4.0.0:

  • support for UNICODE text — starting with Coin 4.0, strings are UTF-8 encoded. we love an encoding upgrade 💖
  • view volume and projectors now support reverse perspective camera settings 👀
  • new SoReversePerspectiveCamera node added 👑
  • new getRadius method added to SoRayPickAction
  • new virtual method getPickedPointForStart added to SoDragger to allow dragging of (partially) covered objects by derived draggers
  • new greater than and less than operators added to SbString
  • implemented SoTextureCoordinateObject for linear texture functions
  • new SoAlphaTest node added ✨
  • support for GLSL/ARB shaders has been added to SoShaderStateMatrixParameter
  • support for linePatternScaleFactor in SoDrawStyle
  • support for newer compilers (she keeps up, periodt)
  • support for DISABLE policy in SoSelection node
  • API changes in SbMatrix, SoPickAction, SoEvent, SoSFTime, SbPList to improve conformance to Open Inventor 2.1 API
  • created public API for converting geo coordinates 🌍
  • auto-linking to the Coin library when using Microsoft Visual C++ compilers
  • updated expat sources to version 2.2.6
  • removed local Boost includes. added configure option --with-boost
  • support for BitBucket and AppVeyor as continuous integration service providers

  • crash in SoText2 when using non-integer font sizes 😭
  • out of bounds access to array in SoSceneTextureCubeMap
  • numerical issues in computation of intersection between sphere and line
  • numerical issue in SbDPMatrix::multLineMatrix()
  • markers are disappearing when clipping planes are present
  • set of invalid VRML identifier characters extended with '(', ')', and '|'
  • replacement for OpenGL extensions string method, obsoleted since OpenGL version 3.0
  • output of scenes containing SoGroup or derived nodes in SoWriteAction
  • force setting color for all indices on TriangleStrips in SoMaterialBundle
bestie that's a whole lot of leaks and crashes fixed. she's not just cute, she's stable. no cap. 💀✨
