Removed the use of the LOOP preprocessor symbol from
the remaining example shader code. The shader code is now
configured according to the types of the resulting patches
without depending on the subdivision scheme of the mesh
topology.
- addition of new shapes -- mainly Loop and Bilinear
- removal of redundant shapes and those not suited to a particular example
- enforced consistent "Patch Type" coloring where provided
- enforced consistent command line usage for common options and Obj input
- enforced consistent default settings on initialization
- added errors and/or assertions where legitimate limitations remain
- improved error handling (OSD errors not being flushed before termination)
This examples is rewritten as a more comprehensive example
of Far and Osd APIs to generate batched index buffer and
vertex buffer, as well as sharing same topology and stencil
table among multiple objects.
Also this change includes an experimental code path of using
glMultiDrawElementsIndirect. It's currently incomplete due to
the missing interface of osd tessellation shader.
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
