rtcSetGeometryVertexAttributeCount - sets the number of vertex attributes of the geometry
#include <embree3/rtcore.h> void rtcSetGeometryVertexAttributeCount( RTCGeometry geometry, unsigned int vertexAttributeCount );
The rtcSetGeometryVertexAttributeCount function sets the number of slots (vertexAttributeCount parameter) for vertex attribute buffers (RTC_BUFFER_TYPE_VERTEX_ATTRIBUTE) that can be used for the specified geometry (geometry parameter).
This function is supported only for triangle meshes (RTC_GEOMETRY_TYPE_TRIANGLE), quad meshes (RTC_GEOMETRY_TYPE_QUAD), curves (RTC_GEOMETRY_TYPE_CURVE), points (RTC_GEOMETRY_TYPE_POINT), and subdivision geometries (RTC_GEOMETRY_TYPE_SUBDIVISION).
On failure an error code is set that can be queried using rtcGetDeviceError.
