NAME

rtcSetGeometrySubdivisionMode - sets the subdivision mode
  of a subdivision geometry

    

SYNOPSIS

#include <embree3/rtcore.h>
void rtcSetGeometrySubdivisionMode(
  RTCGeometry geometry,
  unsigned int topologyID,
  enum RTCSubdivisionMode mode
);

    

DESCRIPTION

The subdivision modes can be used to force linear interpolation for certain parts of the subdivision mesh:

•

RTC_SUBDIVISION_MODE_NO_BOUNDARY: Boundary patches are ignored. This way each rendered patch has a full set of control vertices.

•

RTC_SUBDIVISION_MODE_SMOOTH_BOUNDARY: The sequence of boundary control points are used to generate a smooth B-spline boundary curve (default mode).

•

RTC_SUBDIVISION_MODE_PIN_CORNERS: Corner vertices are pinned to their location during subdivision.

•

RTC_SUBDIVISION_MODE_PIN_BOUNDARY: All vertices at the border are pinned to their location during subdivision. This way the boundary is interpolated linearly. This mode is typically used for texturing to also map texels at the border of the texture to the mesh.

•

RTC_SUBDIVISION_MODE_PIN_ALL: All vertices at the border are pinned to their location during subdivision. This way all patches are linearly interpolated.
