NAME

rtcGetGeometryTransformEx - returns the interpolated instance
transformation for an instance of an instance array geometry for the
specified time.

SYNOPSIS

#include <embree4/rtcore.h>


void rtcGetGeometryTransformEx(
  RTCGeometry geometry,
  unsigned int instPrimID,
  float time,
  enum RTCFormat format,
  void* xfm
);

DESCRIPTION

The rtcGetGeometryTransformEx function returns the interpolated local to world transformation ( xfm parameter) of the instPrimID -th instance of an instance array geometry ( geometry parameter) for a particular time ( time parameter in range [0, 1]) in the specified format ( format parameter). The function can also be used when geometry refers to a regular instance, but then the instPrimID has to be 0.

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 .
