Hi folks,
to give you some hints what's going on right now I added some
information about the recent changes and improvements in OpenSG since
the 1.6.0 release.
Andreas
RenderAction
------------
- much improved transparent sorting speed.
- added a very simple occlusion culling.
renderaction->setOcclusionCulling(true);
I will try to integrate a much more advanced occ from Christoph
Fuenfzig.
- added small feature culling.
renderaction->setSmallFeatureCulling(true);
renderaction->setSmallFeaturePixels(10.0f);
renderaction->setSmallFeatureThreshold(32); // skips the test for
geometries with less than 32 vertices.
- removed the 64 local light sources limit.
Materials
---------
- SwitchMaterial
Similar to a Switch node, just add some materials and switch them
via the choice field.
States
------
- LightModelChunk
- TextureChunk
Added anisotropic texture filtering.
Added support for the npot2 extension.
Cluster
-------
- Added sortlast composer cluster rendering.
- Added new RenderOptions attachment for syncing render action states in
a cluster.
- Added a new improved method for dynamic cluster connections.
Window
------
- Added orthographic camera support.
Misc
----
- Changed OpenGL object handling to use OpenGL allocation functions.
OpenSG won't create it's own gl id's anymore so you can easily
mix OpenSG with other OpenGL rendering code.
- New ImageScaler class for scaling images.
- Added read and write callback to the SceneFileHandler for adding
file compression or encryption.
