5   NAME
6              rtcGetGeometryTransformFromScene - returns the interpolated instance
7                transformation for the specified time

9   SYNOPSIS
10              #include <embree4/rtcore.h>
11
12              void rtcGetGeometryTransformFromScene(
13                RTCScene scene,
14                unsigned int geomID,
15                float time,
16                enum RTCFormat format,
17                void* xfm
18              );

20   DESCRIPTION
21       The  rtcGetGeometryTransformFromScene function returns the interpolated
22       local to world transformation (xfm output parameter) of an instance ge‐
23       ometry  specified  by  its  geometry  ID  (geomID parameter) of a scene
24       (scene parameter) for  a  particular  time  (time  parameter  in  range
25       [0, 1]) in the specified format (format parameter).
26
27       Possible formats for the returned matrix are:
28
29       • RTC_FORMAT_FLOAT3X4_ROW_MAJOR:  The  3×4  float matrix is laid out in
30         row-major form.
31
32       • RTC_FORMAT_FLOAT3X4_COLUMN_MAJOR: The 3×4 float matrix is laid out in
33         column-major form.
34
35       • RTC_FORMAT_FLOAT4X4_COLUMN_MAJOR: The 3×4 float matrix is laid out in
36         column-major form as a 4×4 homogeneous matrix with last row equal  to
37         (0, 0, 0, 1).
38
39       In  contrast  to the rtcGetGeometryTransform function, the rtcGetGeome‐
40       tryTransformFromScene function can get used during rendering  inside  a
41       SYCL kernel.
42
43   EXIT STATUS
44       On  failure  an  error  code is set that can be queried using rtcGetDe‐
45       viceError.
