rtcGetGeometryTransform(3)

NAME


rtcGetGeometryTransform - returns the interpolated instance
  transformation for the specified time

SYNOPSIS


#include <embree3/rtcore.h>
void rtcGetGeometryTransform(
  RTCGeometry geometry,
  float time,
  enum RTCFormat format,
  void* xfm
);

The rtcGetGeometryTransform function returns the interpolated local to world transformation (xfm parameter) of an instance geometry (geometry parameter) for a particular time (time parameter in range [0, 1]) in the specified format (format parameter).

Possible formats for the returned matrix are:

•: RTC_FORMAT_FLOAT3X4_ROW_MAJOR: The 3×4 float matrix is laid out in row-major form.
•: RTC_FORMAT_FLOAT3X4_COLUMN_MAJOR: The 3×4 float matrix is laid out in column-major form.
•: RTC_FORMAT_FLOAT4X4_COLUMN_MAJOR: The 3×4 float matrix is laid out in column-major form as a 4×4 homogeneous matrix with last row equal to (0, 0, 0, 1).

EXIT STATUS

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