// In this example, findPlaneCrossing selects all keys

...


// found on the toe markers LTOE and RTOE that penetrate the

...


// "floor" of the scene, here defined as being all points for

...


// which the Z component is 50 millimeters. The directional

...


// arguments 0 0 1 define the vector of the normal for the

...


// plane, in this case the normal of the plane is aligned with

...


// world Z, pointing straight "up". If you switch the Z

...


// component of the direction argument from 1 to -1, the

...


// command will find all keys that are above the floor.

...


// This example assumes a Z-up environment.
