|
Release 2.4.0
|
|
=============
|
|
|
|
**New Features**
|
|
- Adding functionality to store uniform face-varying data across multiple levels of subdivision
|
|
- Add OsdUtilPatchPartitioner.
|
|
It splits patcharray into subsets so that clients can draw partial surfaces
|
|
for both adaptive and uniform.
|
|
|
|
**Changes**
|
|
- Remove FarMesh dependency from Osd*Context.
|
|
- Use DSA APIs for GL buffer update (if available).
|
|
- Refactor Far API
|
|
- replace void- of all kernel applications with CONTEXT template parameter.
|
|
It eliminates many static_casts from void- for both far and osd classes.
|
|
- move the big switch-cases of far default kernel launches out of Refine so
|
|
that osd controllers can arbitrary mix default kernels and custom kernels.
|
|
- change FarKernelBatch::kernelType from enum to int, clients can add
|
|
custom kernel types.
|
|
- remove a back-pointer to farmesh from subdivision table.
|
|
- untemplate all subdivision table classes and template their compute methods
|
|
instead. Those methods take a typed vertex storage.
|
|
- remove an unused argument FarMesh from the constructor of subdivision
|
|
table factories.
|
|
- Refactor FarSubdivisionTables.
|
|
Delete scheme specialized subdivision tables. The base class FarSubdivisionTables
|
|
already has all tables, so we just need scheme enum to identify which scheme
|
|
the subdivision tables belong to. This brings a lot of code cleanups around far
|
|
factory classes.
|
|
- Move FarMultiMeshFactory to OsdUtil.
|
|
- Move table splicing functions of FarMultiMeshFactory into factories
|
|
- Change PxOsdUtil prefix to final OsdUtil prefix.

|
|
|

|
|

|
|

|
- 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
|
|
=============
|
|
|
|
**New Features**
|
|
|
|
- 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.
|

|
|
**Changes**
|

**Bug Fixes**
|
|
|
|
- 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)
|
|
