NAME rtcSetGeometryTransform − sets the transformation for a particular   time step of an instance geometry
SYNOPSIS #include <embree3/rtcore.h> void rtcSetGeometryTransform(   RTCGeometry geometry,   unsigned int timeStep,   enum RTCFormat format,   const float* xfm );
DESCRIPTIONThe 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 3×4 matrix (3×3 linear transformation plus translation), for which the following formats (format parameter) are supported: • 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 the last row being equal to (0, 0, 0, 1).
EXIT STATUSOn failure an error code is set that can be queried using rtcGetDeviceError.
