NAME

rtcSetGeometryTransform - sets the transformation for a particular
  time step of an instance geometry

SYNOPSIS

#include <embree4/rtcore.h>


void rtcSetGeometryTransform(
  RTCGeometry geometry,
  unsigned int timeStep,
  enum RTCFormat format,
  const float* xfm
);

DESCRIPTION

The rtcSetGeometryTransform function sets the local-to-world affine transformation (xfm parameter) of an instance geometry (geometry parameter) for a particular time step (timeStep parameter). The transformation is specified as a 3Ã4 matrix (3Ã3 linear transformation plus translation), for which the following formats (format parameter) are supported:

	•		`RTC_FORMAT_FLOAT3X4_ROW_MAJOR`: The 3Ã4 float matrix is laid out in row-major form.
	•		`RTC_FORMAT_FLOAT3X4_COLUMN_MAJOR`: The 3Ã4 float matrix is laid out in column-major form.
	•		`RTC_FORMAT_FLOAT4X4_COLUMN_MAJOR`: The 3Ã4 float matrix is laid out in column-major form as a 4Ã4 homogeneous matrix with the last row being equal to (0, 0, 0, 1).

EXIT STATUS

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