The existing code in the node assumes that all the faces in the mesh have the same valence
when populating the component tables describing properties such as per-face material assignment.
This fix accounts for arbitrary topology.
fixes#269
- fix crash in the case of partial uv & color sets
- make sure that the default uv set is not dropped if its name is not 'map1'
note: the current fix carries the first uv set to the refined mesh, but custom
names are dropped and replaced by 'map1'. We appear to be running into a Maya
API bug.
fixes#267
- switch PATHS to HINTS to make sure that we pick up the correct location for various files & libs
- fix the list append to dereference variables properly
- minor code style cleanup
fixes#266
cmake find_path function searchs system directories first when PATHS is used.
using HINTS instead forces the search to start in the suggested locations, which
ensures that the correct headers are used.
fixes#265
minor code cleanups:
- change Descriptor::iterator to use a static vector instead of overly complicated logic
- change the private factory PatchType struct for better readability
- variable name changes
On platforms with multiple devices (e.g. OS X Mavericks
with both Intel and Discrete GPU CL devices) we must
create the context and command queue with the correct
device in order to share resources with GL.
This follows existing patterns (more or less), but
there are certainly opportunities to move more of this
sort of logic into macros defined at the top level.
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
Prevent boundaryEdgeNeighbors[2] from being overrun when an interior
vertex has more than 2 boundary neighbor vertices. The fix is applied
to the GLSL / HLSL and CPU implementations.
Note: this appears to fix long-standing problems with Gregory patches,
but i am not entirely convinced that this fixes the general case.
fixes#259
- renders off-screen a higher resolution version of the current view
- saves the render to image files (screenshot.x.png)
- modified the background color to have alpha set to 0 (screenshots can be composited)
Because our plugin sets UVs with individual face-varying vertices,
Maya interprets the buffer as discontinuous everywhere. Adding a
node in the graph that merges UVs along non-boundary edges resolves
this problem (until the plugin outputs the UV vertex indices in
an aggregated manner).
Also:
- Add a _numVertices member to cpuSmoothNormalContext (for memory reset function)
- Fix memory reset function in cpuSmoothNormalContext (was performing redundant memsets)
- Add a resetMemory boolean to cpuSmoothNormalContext to make reset step optional (default is off)
- 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)
Further leverage cmake object libraries to share object files for CPU
and GPU OSD libraries, avoiding duplicate complation for dynamic/static
build passes.
CMake restricts object library inputs to header and source files, so the
.inc files were renamed to .gen.h (which seems like a better name
anyway) to make CMake happy.
Also updated the .gitignore file to ignore .gen.h files.
