Common Command Line Options
|
||||
===========================
|
||||
|
||||
While the following command line options are common, not all examples support
|
||||
all -- in some cases, certain options are not applicable.
|
||||
|
||||
::
|
||||
|
||||
-f : launches the application in full-screen mode (if supported)
|
||||
-u : apply uniform subdivision to all meshes
|
||||
-a : apply adaptive subdivision to create patches for the limit surface
|
||||
-l depth : level of uniform or adaptive refinement to apply
|
||||
-c count : number of repetitions of the animation loop when supported (default
|
||||
of 0 is infinite)
|
||||
-anim : interpret a given set of Obj files as an animated sequence rather
|
||||
than a set of distinct meshes
|
||||
-catmark : apply the Catmark scheme to all meshes in given Obj files (default)
|
||||
-loop : apply the Loop scheme to all meshes in given Obj files
|
||||
-bilinear : apply the Bilinear scheme to all meshes in given Obj files
|
||||
objfile(s) : a set of one or more meshes in Obj format (requiring a .obj extension)
|
||||
that may be distinct meshes or animated versions of a single mesh

DESCRIPTION
|
||||
===========
|
||||
|
||||
``glBatchViewer`` is a stand-alone application that showcases the primitive
|
||||
batching capabilities of the OpenSubdiv API. Batching is an optimization that
|
||||
enables the merging together of the data tables of many primitives in order to
|
||||
reduce the number of GPU calls.
|
||||
|
||||
Multiple controls are available to experiment with the algorithms.
