6              rtcSetGeometryTimeStepCount - sets the number of time steps of the
7                geometry

9   SYNOPSIS
10              #include <embree3/rtcore.h>
11
12              void rtcSetGeometryTimeStepCount(
13                RTCGeometry geometry,
14                unsigned int timeStepCount
15              );

17   DESCRIPTION
18       The  rtcSetGeometryTimeStepCount function sets the number of time steps
19       for multi-segment motion blur (timeStepCount parameter) of  the  speci‐
20       fied geometry (geometry parameter).
21
22       For   triangle   meshes   (RTC_GEOMETRY_TYPE_TRIANGLE),   quad   meshes
23       (RTC_GEOMETRY_TYPE_QUAD),  curves   (RTC_GEOMETRY_TYPE_CURVE),   points
24       (RTC_GEOMETRY_TYPE_POINT),   and   subdivision  geometries  (RTC_GEOME‐
25       TRY_TYPE_SUBDIVISION), the number of time steps directly corresponds to
26       the  number  of  vertex  buffer slots available (RTC_BUFFER_TYPE_VERTEX
27       buffer type).  For these geometries, one vertex buffer  per  time  step
28       must be specified when creating multi-segment motion blur geometries.
29
30       For  instance geometries (RTC_GEOMETRY_TYPE_INSTANCE), a transformation
31       must be specified for each time step (see rtcSetGeometryTransform).
32
33       For user geometries, the registered  bounding  callback  function  must
34       provide  a  bounding box per primitive and time step, and the intersec‐
35       tion and occlusion callback functions  should  properly  intersect  the
36       motion-blurred geometry at the ray time.

38   EXIT STATUS
39       On  failure  an  error  code is set that can be queried using rtcGetDe‐
40       viceError.
