rtcSetGeometryTransform - sets the transformation for a particular time step of an instance geometry
#include <embree3/rtcore.h> void rtcSetGeometryTransform( RTCGeometry geometry, unsigned int timeStep, enum RTCFormat format, const float* xfm );
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).
On failure an error code is set that can be queried using
