- fixed a broken HTML link
- added emphasis that Loop meshes must be purely triangular
- removed a note listing pre-3.4 restrictions on Loop functionality
Updated the Far Overview and Osd Overview and shader
interface pages for 3.4 to include a discussion of
trianglular patch types and other minor updates.
-Fixed the iOS ViewController to set the correct irregular
patch approximation mode.
-Fixed the setting of fractionalSpacing to be separate from
screenspace tessellation.
-Fixed the configuration of the internal stage-in setting
on embedded builds.
- added new pair of figures illustrating the concept of basis functions
- updated the Subdivision Surfaces page to insert the new figures
- replaced stand-in figures for the animated mesh with three unique poses
- minor changes to Doxygen comments based on feedback
- new description for PatchTableFactory::Options::EndCapType
- fixed warnings related to Doxygen use of <REAL> in patchTable.h
Reorganized the character cells used for UI
elements and removed elements that were not
being used in order to provide more space
for the logo image and logo text.
Updated to the new OpenSubdiv logo and updated
the HUD drawing code used to display the logo
character cells.
These changes update the mtlPtexViewer implementation
to match recent changes to the mtlViewer including:
- improved shader organization
- correct screenspace tessellation
- support for common command line arguments and fit to frame
Updated the mtlViewer to make use of common/argOptions.h
like the other viewers and also implemented a "fit to frame"
hotkey. Both changes help improve manual testing.
Patches with transition edges were not being tessellated
correctly when drawing multiple patch types, e.g. with
Gregory or Legacy Gregory approximation at irregular features,
because the per-patch tess factors buffer was not being
offset correctly for the draw command for each patch type.
Fixed this to be consistent with other patch drawing by
recording and applying offsets when binding this buffer
for each patch type, and making sure that attributes for
the tess factors buffer are bound when drawing Legacy Gregory
patch types.
Removed the use of the LOOP preprocessor symbol from
the remaining example shader code. The shader code is now
configured according to the types of the resulting patches
without depending on the subdivision scheme of the mesh
topology.
Removed the use of the LOOP preprocessor symbol from
the glFVarViewer shaders code. The shader code is now
configured according to the types of the resulting patches
without depending on the subdivision scheme of the mesh
topology.
Improved the implementation of face-varying interpolation
similar to the glFVarViewer. Now the face-varying patch
type is obtained from the face-varying patch array
descriptor instead of being hard-coded by subdivison scheme.
Removed the use of the LOOP preprocessor symbol from
the glFVarViewer shaders code. The shader code is now
configured according to the types of the resulting patches
without depending on the subdivision scheme of the mesh
topology.
This allows the implementation of face-varying interpolation
to be improved and simplifies both the shader code and
application code.
Also, fixed a couple of incorrect buffer/texture bindings
that were raising GL errors.
