Linear

constant value of displacement, velocity, or acceleration.

Curve

motion expressed in the form of a displacement, velocity, or acceleration curve that is a function of an independent variable.  Generally, the independent variable is a function of TIME.

Select AKIMA, CUBIC, LINEAR , or QUINTIC under Interpolation as the method of interpolation of between two data points in the curve.   Enter a value under Independent variable.  Resolve the curve by clicking Curve and selecting a curve from the Select a Curve dialog.

When using curve data; a curve, interpolation method, and an independent variable must be specified in the form of a solver expression.  The solver expression may refer to MotionView attributes specified in the Templex syntax.

Spline3D

Motion expressed in the form of a 3D spline which is a function of two independent variables.

Select AKIMA, CUBIC, LINEAR, or QUINTIC under Interpolation as the method of interpolation of values between 2 data points in XY plane. Resolve the 3D spline by clicking on the Spline3D collector and selecting a Spline3D entity from the Select a Spline3D dialog.  Specify an expression each under Independent variable X and Independent variable Z.

Expression

displacement, velocity, or acceleration expressed in the form of a solver expression.
