- fix default selection for pulldown widgets
- move widgets around to prevent overlap in examples
- add a little triangle indicator to the pulldown widget
- switch color from white to yellow for selected pulldown item
- switch shading radio buttons to pulldowns
- re-ordered elements on screen in most viewers
note: the ptex viewer has not been updated to the new look yet
The example code now uses the new glfw*FramebufferSize methods
to determine the size of the windows's framebuffer for rendering
and glfw*WindowSize method for user interaction
Fixes#263
- added a _stringify function to top CMakeLists
- switched all stringification tasks to use the macro
- all suffixes are now .gen.h instead of .inc (to help cmake track dependencies)
Important notice: all client shader code must have following functions and compose them to osd intrinsic shaders (vertex/tessEval/tessControl)
mat4 OsdModelViewMatrix()
mat4 OsdProjectionMatrix()
mat4 OsdModelViewProjectionMatrix()
float OsdTessLevel()
int OsdGreogryQuadOffsetBase()
int OsdPrimitiveIdBase()
We probably should write a utility class for basic binding of them, to make client code simpler.

GLFW 3.0.1 made the reshape callback explicit. Since we are using it to setup some framebuffers,
we need to call this function ourselves before starting the main-loop.
fixes#181
- fix FindGLFW.cmake to match the new locations
- fix all viewer & examples to build with 3.0, 3.0.1 and 3.0.2
Note : ptxViewer and paintTest do not work with 3.0.1 and 3.0.2 (yet)
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.
- 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.
fixes#143
