New Features in Coin v4.0.0

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.

The build system has been migrated from GNU Autotools to CMake.

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).
  • 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
  • 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
