d2abf61c56 Added adaptive tess of user varying values
This isn't necessarily a final design, but
it gets enough of the pieces in place to move
forward.

21b9fbbb95 Moving some member variables of OsdGlDrawContext from public to protected
and adding the requisite accessors

Note : all our example code goes through the same boiler-plate texture
binding code - we might want to move it as a member function of the DrawContext.

b815aff333 First pass at fixing the installation part of the Cmake build : now CMAKE_INSTALL_PREFIX can
be used as intended to specify an installation directory, which can be located anywhere on the
file system.

Also improved the doxygen target and made the doxy build "quiet".

e6e7c96a52 We need to leverage our per-patch ptex indexing scheme in the EvalLimit API.
- replace ptex indexing with the FarPtexCoord structure as a way to pass per-patch
  ptex data to the shaders.

  We are replacing a vector<int> arranged as :
  int[0] : ptex face index
  int[1] : (u,v) as 16 bits encoding the log2 coordinate of the top left corner

  Instead we are now using a struct arranged as :
  int[0] : ptex face index
  int[1] : is a bit-field containing u,v, rotation, depth and non-quad

  The u,v coordinates have been reduced to 10 bits instead of 16, which still
  gives us a lot of margin.

- Replace OsdVertexBufferDescriptor with something more adequate for general
  primvar representation (this name will probably eventually change...)

- Improve OsdPatchDescriptor
    - add a "loop" boolean (true if the patch is of loop type)
    - add a GetPatchSize() accessor

- OsdPatchArray :
    - remove some redundant elements (still more to do there)

- Fix all shader / examples / regressions & stuff to make this all work.

d026aca006 use std::string instead of char* for regression shapes definition,

a4c43b0522 fix some GLFW 3.0 issues - since we are still in beta, the API is changing a bit
- the closeWindowFun callback changed prototype (now returns void)
- keyboard functions now require the window handle (and pass it to the callback)

8efecb0fca Batching stuffs: generalized kernel batches, table/dispatcher refactoring, multiMeshFactory, drawContext, etc.
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector

Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)

ea1a87441f Add support for hierarchical hole edits.
- add tag parsing for h-hole in shape_utils
- re-create Renderman's test shape from the documentation (catmark_square_hedit.h)
- fix Hbr to correctly pass the hole tag from parent to child face
- fix FarSubdivisionTables to handle disconnected face-vertices without crashing

25f79e7ff2 - change adaptive refinement in FarMeshFactory to not refine inside holes,
while retaining a necessary 1-ring on the inside of a hole edge

- add IsInsideHole() function to HbrHalfEdge

- add HasChild() function to HbrVertex and HbrHalfedge

- add a regression shape with adjacent holes and creases (tests dart, crease & boundaries)

Note : this does not address hierarchical edits inside holes or hole tags in hierarchical edits

452b30f72f OsdMesh no longer owns its ComputeController
Now a ComputeController is passed as an
argument to OsdMesh::Create(). This is
a better match to the underlying object
model and can be much more efficient for
compute controllers that have expensive
resources, e.g. compiled shader kernels.

1befe72c9f glViewer: exit when the window is closed 2013-02-16 13:26:46 -08:00

a52c70ab8b First pass implementation of holes :
- make sure HBR passes down the hole tag to children when subdividing faces
- minor API modification : allow to unset the hole flag on a face
- modify uniform / adaptive FarMeshFactory to be aware of the flag
- make the FarSubdivisionTableFactory assert when finding unconnected HBR vertices (as it should)

* Uniform subdivision :
    The refinement scheme only creates faces & vertices necessary
    to maintain the one-ring around the edges of a hole, so this solution
    is quite efficient.

* Adaptive subdivision :
    At the moment we are still performing full topological analysis on holes and
    only skipping patches associated to holes. This is sub-optimal in 2 ways :
        1. the topological analysis can potentially be cranking on a lot of unnecessary
           geometry
        2. even though we may not be drawing the patches, the compute stage is still
           applying kernels on all the control vertices of these patches.
    We will have to revisit feature adaptive subdivision & holes, so keep the issue active.

6f5d1e34be partial solution to run-time environment configuration :
- add bool OsdGLDrawContext::SupportsAdaptiveTessellation() method
- modify glViewer to use that instead of #ifdefs

Note : this is not the final word on this as OSD really needs a more comprehensive
system to provide run-time information about available features to the client code.

2b12ffc447 build fixes :
- remove ptexViewer from the build on OSX (doesnt work)
- remove maya plugins from the build on OSX (until we have a compatible version available)

glViewer fixes :
- fix incorrect GLFW version check in #ifdefs (now done in cmake)
- fix default program GL version (downgraded to 1.5 where necessary)
- remove non core-profile GL calls (triggering errors)

this should allow OSX 10.7 builds to produce a functional, if restricted, glViewer.

ab4f79c128 Remove deprecated GL calls, comply with 4.2/3.3 core profile. Use VAO, update glsl shaders, remove immediate draws, etc.
In example code, GLUT has been replaced with GLFW so that glViewer/ptexViewer can run on OSX (10.7 or later).

OSX note: still have some problem with clang, may need to explicitly specify gcc on cmake cmdline
 -DCMAKE_CXX_COMPILE=/usr/bin/g++
