to project the position of the object. The coefficients are in the form ax+by+cz+d=0.
For example, if you use the default plane equation coefficients to [0 1 0 0] for the
vrtkoff_trace model, then after you simulate the model, the object positions project to the
y=0 plane.
Project positions to a point— Displays line segments from an object to a point to
approximate the trajectory of the object.
• None — (Default) No projection to a point.
• Defined in block mask — If you select this option, enter coordinates in the
Projection point coordinates edit box.
• Defined in the block input — If you select this option, specify the coordinates
of the point in the output of a block that inputs to the VR Tracer block.
