 I would be very interested in any info on the emerging concept of "point
 graphics" which is a graphics model assuming 'smart pixels' -- w.g., in 
 an animation sequence involving the possibility of 2 or more objects
 colliding, the first (i.e., fastest) object first sets a pixel-set to
 the value 'occupied' so that other objects moving into the set will
 cause a collision to be sensed. Presumably, the intent is to avoid
 computation of first- and second-degree simultaneous equations to
 decide presence of collision.
 I believe each pixel is represented by a record containing more info
 than just whether it is occupied (color, hue, etc.)

 Thanks for any help whatever.
