- 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)
- 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
- 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
Previously, the glEvalLimitViewer was hard coded to
use only adaptive refinement, but this change demostrates
how to evaluate patch locations on the linear patches
resulting from a uniform refinement.
By default, in a patch table created from a uniform refinement,
the patch indices for vertex patches account for base level indices,
while the patch indices for face-varying patches do not account for base
level indices.
This change also updates the example to set the patch table factory options
so that both kinds of patch indices account for base level indices.
This updates the patch basis evaluation functions in Osd
to match recent changes to far/patchBasis.
This also exposes a common facility for dealing with PatchCoord,
PatchArray, and PatchParam. These are exposed as global functions
operating on struct data, since C++ style class methods are not
supported by all of the Osd shader and kernel execution envirionments.
Changes:
- Merged far/patchBasis.cpp to osd/patchBasisCommon{,Types,Eval}.h
- Exposed PatchCoord, PatchArray, and PatchParam to Osd kernels
- exposed OsdEvaluatePatchBasis and OsdEvaluatePatchBasisNormalized
- Updated CPU, TBB, Omp, CUDA, OpenCL, GLSL, HLSL, and Metal evaluators
- Updated glFVarViewer
- added conversions Shape and Sdc scheme types
- extended ObjAnim to take a scheme type on construction
- updated far/tutorial_9 to make use of new functionality
- changed the main OPENSUBDIV_INCLUDE_DIR to exclude ./opensubdiv
- updated CMakeLists.txt files in non-examples to use only this path
- updated CMakeLists.txt files in examples to append ./opensubdiv to path
- updated source in regression/common to use #include <opensubdiv/...>
- updated source in examples/common to use #include <opensubdiv/...>
- deferred source in examples to be updated on a case-by-case basis
Updated Metal patch shaders to resolve degenerate normals.
This fix was ported from the GLSL patch shader source.
Also, added missing inf sharp test cases to mtlViewer.
Updated HLSL patch shaders to resolve degenerate normals.
This fix was ported from the GLSL patch shader source.
Also, added missing inf sharp test cases to dxViewer.
The glImaging test now checks the GL version of the
current context before attempting to run GL XFB or
GLSL Compute kernels.
This example can run as part of the ctest suite during
continuous integration testing and adding these checks
should improve consistency of runs across different
test conditions.
Updated mtlPtexViewer to account for recent
API changes to Osd::MTLPatchShaderSource and
also fixed a build error when building with
the use of PtexCache disabled.
- Added support for OSX CI builds and tests
- Cleaned up build scripts and moved to $ROOT/build_scripts
- On Linux: moved to trusty distro
- On Linux: enabled OpenMP, TBB and PTex build options
- On Linux: install and setup xvfb with newer mesa drivers to run our GL tests
- On Linux: enable GL tests
- added Far::PatchTableFactory::Options::generateLegacySharpCornerPatches
- legacy behavior of sharp patches at smooth corners preserved by default
- added corresponding option bit to Osd::MeshBits
- updated examples/glViewer with option
- added detection of shapes without UVs and report fatal error
- fixed command line parsing of shape file arguments and other options
- added missing UVs from shapes/catmark_fan
Read all comments and made corrections to files that aren't part of
OpenSubdiv itself but are packaged with it.
Commandline output of glPtexViewer is affected. Otherwise no functional
changes.
Noticed a few typos when browsing comments. Proceeded with a "manual
spell check", reading all comments and tweaking spelling, grammar,
punctuation.
Didn't bother with Hbr library.
Comments only, no functional changes.
The methods which return arrays of FVarPatchParam have
been made plural, e.g. GetFVarPatchParams(), for consistency
with the other methods in PatchTable.
Also fixed a missing doxygen tag.
Also removed the remaining Maya dependencies. These
were most useful during the early days of OpenSubdiv.
Now OpenSubdiv has been integrated directly into Maya
and these examples serve little purpose.
