stb - potential use of uninitialized variable (this may have been safe)
farViewer - unused variable
patchTableFactory - _channelIndices potentially used uninitialized
FVarLevel - valueIndexInFace0 potentially used used uninitialized (was safe)
We'll restore this code and finish it up for the next release.
For now, removing this code restores parity with the 3.0 beta,
i.e. face-varying patches are always all bilinear.
There's a lot of good foundational work here to eventually support
smooth interpolation of face-varying patches. Unfortunately, this
is not quite ready to release. Therefore, we've decided to defer this
feature until a later release.
This change hides this code behind the FAR_FVAR_SMOOTH_PATCH macro.
Now the channel specifier is the last parameter in a method's
parameter list with a default of 0. This is consistent with the
topological face-varying queries and also simplifies the common
case of just a single face-varying channel.
- the framebuffer class in examples/common is unstable in certain drivers.
removing offscreen rendering for now.
- move screenshot function to GLUtils.
- fix vertex attrib binding bug (not showing control mesh on osx)
The GLFW context version hint is a minimum version, not maximum version so
requesting 4.4 and then falling back to lower versions doesn't make sense.
This change sets the minimum version to 3.2 and attempts to standardize this
across all example apps.
Also print the maximum supported GL version along with the context version
at startup.
- removed all of the multi-level Interpolate...() methods taking T*, U*
- made all single-level methods consistent wrt usage of T&, U&
- replaced usage in regressions, tutorials and examples
- additional minor improvements to far/tutorials
To encapsulate endcap functions from public API, add methods to
tell the number of patch points needed (GetNumLocalPoints()) and
to compute those patch points as a result of change of basis from
the refined vertices (ComputeLocalPointValues()).
ComputeLocalPointValues takes contiguous source data of all levels
including level0 control vertices.
All examples, regression tests and tutorials directly looked into
opensubdiv source directory to grab the header files. This is somewhat
convenient during development but they can mistakenly access private
header files.
With this change, when OPENSUBDIV_INCLUDE_DIR is given to cmake,
it will be used as an include search path to build examples etc.
Otherwise it follows the same behavior as before.
Also replaces include references to the files in regression dir
to be relative, and cleanups some copy-paste patterns.
- created new class Far::PrimvarRefiner with interpolation methods
- removed interpolation and limit methods from Far::TopologyRefiner
- replaced internal usage in Far::StencilTableFactory
- replaced usage in regressions, tutorials and examples
- replaced Evaluate() with EvaluateBasis() in far/tutorial_6
- commented out use of EvaluateFaceVarying() in examples/farViewer
- face-varying patches are work in progress
The code in farViewer that was used to draw the Hbr representation
of meshes is now gone. This code was mostly used as a way to compare
against the Vtr implementation. However, we don't want this to serve
as an example for others as the Hbr code is not meant to be instructive
otherwise.
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.
