Collision Path Sample
Collision Path sample demonstrates programming of
Path Collision Detection.

Running the application
The application expects the model to have at least two top level objects.
Names of the first and the second objects are displayed on the right hand side
of the form. Each object has an associated
Movement defined by an
array of frames
When Path check box is on, a red line in 3D shows path of movement of the
current object. Turn off Objects check box and turn on Points to see a clearer
picture. Path of the second object is not visible by default when the current
object has changed to 1 because the second object only rotates around its
constant location.
On click of the Animate button the application calculates collision moment and
will move along paths defined by the Path group of controls until the collision
is reached. If there was no collision, the objects will run full length of the
path and will stop at the end.
The top Up Down control in the Current Object group changes between objects
in the model. When Static check box is on the objects will not move so its path
does not have to be defined.
Path of the current object is defined by an array of frames, which can be
edited using the Path group. Size of the array can be increased with the Frame
Count control, so a smoother or more complicated movement can be defined. The
current frame is rendered in 3D when the "Current Frame" check box is on.
The Quadratic Interpolation option in the Interpolation group makes the path
a smooth curve fit into location points, which are origins of frames from the
frame array. Turn on
Points check box to see the point set.
Reset button restores display to the initial position of the movement after
the previous animation.
