5   NAME
6              rtcSetGeometryTopologyCount - sets the number of topologies of
7                a subdivision geometry

9   SYNOPSIS
10              #include <embree4/rtcore.h>
11
12              void rtcSetGeometryTopologyCount(
13                RTCGeometry geometry,
14                unsigned int topologyCount
15              );

17   DESCRIPTION
18       The  rtcSetGeometryTopologyCount function sets the number of topologies
19       (topologyCount parameter) for the specified subdivision geometry (geom‐
20       etry  parameter).   The  number of topologies of a subdivision geometry
21       must be greater or equal to 1.
22
23       To use multiple topologies, first the  number  of  topologies  must  be
24       specified,  then the individual topologies can be configured using rtc‐
25       SetGeometrySubdivisionMode and by setting  an  index  buffer  (RTC_BUF‐
26       FER_TYPE_INDEX) using the topology ID as the buffer slot.

28   EXIT STATUS
29       On  failure  an  error  code is set that can be queried using rtcGetDe‐
30       viceError.
