- Make sure to declare usage of the include files if GLFW is found
- When GLFW is found and is compiled into examples/common, we need to
unfortunately link it into dxViewer. Hopefully we can refactor common
so that this won't be necessary in the future.
This change refactors the GLSL and HLSL patch shader code so that
most of the work is implemented within a library of common functions
and the remaining shader snippets just manage plumbing.
There is more to do here:
- varying and face-varying data can be managed entirely by the client
- similarly, displacement can be implemented in client code
- there's still quite a bit of residual boiler-plate code needed
in each shader stage that we should be able to wrap up in a more
convenient form.
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
We will need to find a solution for Ignacio's older setup, but this at least
fixes the other fallout.
* Use glewIsSupported instead of glewGetExtension
* Convert tabs to spaces
* Remove GLEW static caching (they only get called once)
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.
- removed AddVaryingWithWeight from Far::PrimvarRefiner interpolation
- removed Far::StencilBuilder dependencies on varying
- updated Far::StencilTableFactory use of StencilBuilder constructor
- updated far/tutorial_2 to use vertex colors vs varying (for now)
- added TopologyRefiner base level modifiers to TopologyRefinerFactoryBase
- removed old modifiers from TopologyRefiner (unused by anything else)
- updated existing Factory<MESH> definitions to use new methods
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.
- updated PrimvarRefiner to make use of now-local Mask class
- renamed vtr/maskInterfaces.h to vtr/componentInterfaces.h
- updated usage of renamed header file and CMakeLists.txt
