NAME

rtcSetGeometryTopologyCount - sets the number of topologies of
  a subdivision geometry

SYNOPSIS

#include <embree3/rtcore.h>

void rtcSetGeometryTopologyCount(
  RTCGeometry geometry,
  unsigned int topologyCount
);

DESCRIPTION

The rtcSetGeometryTopologyCount function sets the number of topologies (topologyCount parameter) for the specified subdivision geometry (geometry parameter). The number of topologies of a subdivision geometry must be greater or equal to 1.

To use multiple topologies, first the number of topologies must be specified, then the individual topologies can be configured using rtcSetGeometrySubdivisionMode and by setting an index buffer (RTC_BUFFER_TYPE_INDEX) using the topology ID as the buffer slot.

EXIT STATUS

On failure an error code is set that can be queried using rtcGetDeviceError.
