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 );

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