## NAME

coin310 - New Features in Coin v3.1.0

This is a brief summary of the new features in Coin v3.1.0:

- •

  Default transparency type for **SoGLRenderAction** changed from SCREEN\_DOOR to BLEND.

- •

  **SoBase** will not keep a list of unnamed / empty named nodes any more. This is both an optimization and improves conformance to SGI / TGS Inventor.

- •

  **SbTesselator** does better when handed certain polygons, due to improved precision in internal calculations.

- •

  Resource usage pressure significantly lower for common case scene graphs with regard to mutex allocations. A not entirely uncommon problem on MS Windows systems for huge scene graphs was that the run-time system ran out of available mutexes -- this is now very unlikely to happen.

- •

  Builds with G++ and MSVC will have C++ exception support enabled by default.

- •

  **SoSceneManager** render callback can be set to NULL to disable it.

- •

  Non-power-of-two textures are automatically supported if the OpenGL driver has that feature.

- •

  No other intentional differences in semantics, other than for any bugs fixed.
