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
