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)
|
|
-yup : set initial view with Y-axis up (Z-up is the default)
|
|
-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
