Member Enumeration Documentation

enum EndCapType

Choice for approximating irregular patches (end-caps)

This enum specifies how irregular patches (end-caps) are approximated. A basis is chosen, rather than a specific patch type, and has a corresponding patch type for each subdivision scheme, i.e. a quad and triangular patch type exists for each basis. These choices provide a trade-off between surface quality and performance.

Enumerator
ENDCAP_NONE	unspecified
ENDCAP_BILINEAR_BASIS	use linear patches (simple quads or tris)
ENDCAP_BSPLINE_BASIS	use BSpline-like patches (same patch type as regular)
ENDCAP_GREGORY_BASIS	use Gregory patches (highest quality, recommended default)
ENDCAP_LEGACY_GREGORY	legacy option for 2.x style Gregory patches (Catmark only)
