lighting; alternatives to xinteranimate [message #34533]

1. How does one produce uniform lighting of a surface, such as
topography from a DEM, during rotation. I have experimented with
idlgrlight with type set to 1, and with both a fixed light source and
one that rotates with the model, but seem to get quite variable, and
even spotlight-like, light intensities during rotation.

2. I am making animations of earthquakes seen beneath a transparent
topographic surface. At present the memory limitation imposed by my
video card limits me to about 150 frames. For xinteranimate each frame
consists of an image of both the earthquakes and topography. The
earthquakes change with each frame, but the topography remains the
same. Thus it would be advantageous to produce frames with only the
earthquakes, then play the animation using a single image of the
topography as a constant background to each frame. I figure this could
save much memory, allowing many more animation frames to be created.

Does an alternative to xinteranimate (with the same ability to control
the rate of animation) exist that could do this?
