On Windows we now look for and use an explicit python interpreter to
find the version of docutils installed. There is more information in
the commit, but it would result in a much cleaner change if we could
decide that it's okay to do this for all platforms. For now, just do it
for Windows to get us unblocked.
This script is intended to make building OpenSubdiv with all its various options easier to manage. It will automatically download and install the dependencies where it can (e.g., it can get GLEW automatically, but it can't get the CUDA SDK).
This is a fork of the similar script found in the USD repo.
- Add search path for Windows 10 support for DirectX SDK
- Turn off searching the default paths for the DirectX libraries and
instead use the explicit paths provided. On certain configurations,
this fixes the case where cmake will pick up the librariees for the wrong
architecture
- Be more explicit when a required DirectX library is not found instead
of silent failure.
As mentioned in issue #997, OpenSubdiv still uses CUDA functionality
that is being deprecated. When warnings are treated as errors, this
can make OpenSubdiv fail to compile. For now, we turn off these
deprecation warnings until we can address them.
- added far/tutorial_10 illustrating variable width vertex class
- revised far/tutorial_9 for command line and documentation conventions
- updated doc/tutorials.rst with missing and new tutorial descriptions
- addition of new shapes -- mainly Loop and Bilinear
- removal of redundant shapes and those not suited to a particular example
- enforced consistent "Patch Type" coloring where provided
- enforced consistent command line usage for common options and Obj input
- enforced consistent default settings on initialization
- added errors and/or assertions where legitimate limitations remain
- improved error handling (OSD errors not being flushed before termination)
The computation to adjust patch evaluation weights
for box spline triangle patches to account for boundaries
has been updated to use simple conditional logic instead
of index indirection tables. This results in better register
resource usage for some shader compiler implementations.
Previously, these methods could fail to compile on some
systems.
- replaced use of "LimitPoints" functions in all patch shaders
- removed the unreleased "LimitPointsTriangle" functions
- added internal tess functions for processing patch boundaries
- updated Bezier quad and tri tess evaluation to use boundary functions
- renamed core "LimitPoints" functions to reflect the patch type (Bezier)
- overloaded new functions with the additionally computed tess level
- preserved stubs of all "LimitPoints" functions for compatibility
- Removed restriction on adaptive refinement for Loop meshes
- Updated internal class used to manage eval locations for triangle patches
- Added command line options to specifiy the Scheme for .obj input files
- changed Far::PatchDescriptor size for GREGORY_TRIANGLE to 18
- modified Far::LoopPatchBuilder to construct full quartic Gregory patch
- fixed Far::LoopPatchBuilder bug related to face points near boundaries
- updated Far patch basis evaluation for Gregory and Bezier triangles
- updated Osd patch basis evaluation to match Far
- updated Osd GLSL patch size for Gregory triangle to 18
- modified Osd GLSL Gregory triangle eval and tess settings for quartic
- updated sizes for the Box-spline triangle shader to generate 15 points
- updated conversion of Box-spline from hybrid Bezier to fully quartic
- added resolution of degenerate normal to Bezier triangle evaluation
- updated hybrid Gregory triangle conversion to quartic Bezier
- updated adaptive tessellation of Bezier triangle for quartic boundaries
- Removed Catmark restrictions in the application code and shaders
- Added command line options to specifiy the Scheme for .obj input files
- Added support for Linear end-cap approximation
- Updated GUI labels for end-cap types, i.e. "Linear" instead of "Bilinear"
and "Regular" instead of "BSpline".
- Added new shading color to glViewer for "Patch Depth"
- Disabled screen-space and fractional tessellation by default
