Motion_curve Data Type

Declaration:

motion_curve <name> ( <curve>, in = <pre extrapolation type>, out = <post extrapolation type> )

Reference:

<name>

Literal:

motion_curve ( <curve>,

in = <pre extrapolation type>, out = <post extrapolation type> )

Purpose:

This allows you to specify a 3D spline curve to be used for animation. Usually the spline curve is used as a motion path. The extrapolation type arguments define how to evaluate the curve outside of its usual range. The motion_curve data type is usually used in conjunction with the extract and animate functions.

Example:

motion_curve motion_path ( curve#2, 
	in = PRE_CONSTANT, out = POST_CONSTANT );
