rprShapeSetMotionTransformCount

Defines the number of transforms for a frame for a shape set with rprShapeSetMotionTransform.

rpr_status rprShapeSetMotionTransformCount(	rpr_shape shape,
	rpr_uint transformCount);

Parameters

Parameter	Description
shape	`rpr_shape` to enable multiple motion transforms for.
transformCount	Number of transform samples for this shape.

Example

To create a motion from matA to matB:

rprShapeSetTransform(shape, false, matA) // matrix at time=0
rprShapeSetMotionTransform(shape, false, matB, 1) // matrix at time=1
rprShapeSetMotionTransformCount(shape,1) // use 1 motion matrix

Return

Returns RPR_SUCCESS in case of success, or RPR_ERROR code if a problem was encountered.
