The following changes are discussed in this document:

1.1. Open Inventor Renovation and New Modules

Renovated the Open Inventor core by using vertex arrays and VBO to enhance efficiency of renderings.
Added new class SoIndexedTriangleSet to further enhance speed.
Added modules to render screen space ambient occlusion, and cascaded shadow mapping and soft-shadows (PCSS).
- SoScreenSpaceAmbientOcclusion
- SoShadowMapping
Added SoRenderSurfaceIntersection to render 3D surface intersections on 2D slices.
- SoRenderSurfaceIntersection
Added SoFixedFunctionShader to extent the fixed function Open GL pipeline with user shaders.
- SoFixedFunctionShader
Supporting MSAA (multisample anti-aliasing) in SoExaminerViewer, SoFramebufferSampler2D, and OffscreenRenderer.
Module SoDiagram2D replaces Diagram2D and offers extension modules for rendering curves.
- SoDiagram2D
