LedCount.itx
Type: None
Overview:
=========
This Imagine 3.x texture can optionally blink the LED when a ray strikes
it and/or keep track of the total number of hits.
At least a 68020 and an FPU are required. The integer version of Imagine is
not supported, sorry.
Usage:
======
This is a simple texture to apply. There are only two settings, one to
control the LED blink, and another to keep track of the ray hits. The
included program ShowCount will display the number of ray hits after
or during a render. The ray counting is a bit of a hack. It uses
location $0 to keep track of ray hits. Location $0 is cleared when the
texture is called before rendering, and then updated each time the
texture is called. If you have an MMU and use Enforcer, you will get a
large number of errors if you use this function. You have been warned.
Future:
=======
Is there one? I could do this in a system-friendly manner I suppose,
but is anyone interested? As it stands, I really can't think of a real
use for this texture other than "Gee, neat flashing light." so improving
it is not a high priority. I'd be interested if anyone does find this
useful. :-)
