Release 1.2.4
|
|
=============
|
|
|
|
- Adding support for fractional tessellation of patches
|
|
- Adding a much needed API documention system based on Docutils RST markup
|
|
- Adding support for face-varying interpolation in GLSL APIs
|
|
- Adding varying data buffers to OsdMesh
|
|
- Adding accessors to the vertex buffers in OsdGlMesh
|
|
- Adding face-varying data to regression shapes
|
|
- Cleanup of common bicubic patch shader code (GLSL / HLSL) for portability
|
|
(ATI / OSX drivers)
|
|
- Fix FarVertexEditTablesFactory to insert properly vertex edit batches
|
|
(fixes incorrect hierarchical hole in regression shape)
|
|
- Fix FarPatchMap quadtree to not drop top-level non-quad faces
|
|
- Fix Gregory patches bug with incorrect max-valence
|
|
- Fix FarPatchTables::GetNumFaces() and FarPatchTables::GetFaceVertices()
|
|
functions to return the correct values
|
|
- Fix face indexing GLSL code (ptex works on non-quads again)
|
|
- Fix face-varying data splicing in FarMultiMeshFactory
|
|
- Fix ptex face indexing in FarMultiMeshFactory
|
|

|
Release 1.2.3
|
|
=============
|
|
|
|
- EvalLimit API refactor : the EvalContext now has dedicated structs to track all
|
|
the vertex, varying and face-varying data streams. Also renamed some "buffers"
|
|
into "tables" to maintain code consistency
|
|
- EvalLimit optimization : switch serial indexing to a quad-tree based search
|
|
- Adding Varying and Face-Varying data interpolation to EvalLimit
|
|
- Face-varying data bug fixes : making sure the data is carried around appropriately
|
|
Fixes for OpenCL use with the new batching APIs
|
|
- GLSL general shader code cleanup & fixes for better portability
|
|
- GLSL Tranform Feedback initialization fix
|
|
- Critical fix for FarMultiMesh batching (indexing was incorrect)
|
|
- Fix osdutil CL implementation (protect #includes on systems with no OpenCL SDK
|
|
installed)
|
|
- Fix face-varying interpolation on adaptive patches
|
|
- FarPatchTables : fix IsFeatureAdaptive() to return the correct answer
|
|
- Fix Far factories to handle the absence of face-varying data correctly.
|
|
- Many GLSL shader code style fixes which should help with ATI / OSX shader compiling
|
|

|
|
Release 1.2.2
|
|
=============
|
|
|
|
- Introducing the EvalLimit API : the Eval module aims at providing support for
|
|
computational tasks that are not related to drawing the surfaces. The EvalLimit
|
|
sub-module provides an API that enables client code to evaluate primitive variables
|
|
on the limit surface.
|
|
- Osd<xxx>ComputeController : minor optimization. Added early exit to Refine method
|
|
to avoid unnecessary interop.
|
|
- OsdGLDawContext : minor API change. Protecting some member variables and adding
|
|
const accessors
|
|
- OsdError : minor API refactor, added Warning functions.
|
|
- Fix Ptex bug : prevent corner texel guttering code to from going into infinite
|
|
loops
|
|
- Adding the ability for a FarMeshFactory to construct patchTables starting from
|
|
'firstLevel' in uniform subdivision mode
|
|
- Consolidating the color coding of bicubic patch types through all our our code
|
|
examples (this is used mostly as a debugging tool)
|
|
- Fixing some MSVC++ build warnings
|
|
- Update to the outdated README.md
