rtcGetGeometryTransform(3) Embree Ray Tracing Kernels 3 NAME rtcGetGeometryTransform - returns the interpolated instance transformation for the specified time SYNOPSIS #include void rtcGetGeometryTransform( RTCGeometry geometry, float time, enum RTCFormat format, void* xfm ); DESCRIPTION The 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: o RTC_FORMAT_FLOAT3X4_ROW_MAJOR: The 3x4 float matrix is laid out in row-major form. o RTC_FORMAT_FLOAT3X4_COLUMN_MAJOR: The 3x4 float matrix is laid out in column-major form. o RTC_FORMAT_FLOAT4X4_COLUMN_MAJOR: The 3x4 float matrix is laid out in column-major form as a 4x4 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. SEE ALSO [RTC_GEOMETRY_TYPE_INSTANCE], [rtcSetGeometryTransform] rtcGetGeometryTransform(3)
