agradeneu Posted May 12 Share Posted May 12 can you do a parallax scroller, e.g. like in Sonic or Street Fighter 2 (floor persepective effect)? Quote Link to comment Share on other sites More sharing options...
42bs Posted May 12 Author Share Posted May 12 This is ray tracing, so a completely different thing. 1 Quote Link to comment Share on other sites More sharing options...

On could use any, but it looks ugly when the spheres are distant if the texture has to many details. Quote Link to comment Share on other sites More sharing options...
Cyprian Posted May 13 Share Posted May 13 (edited) @42bs congrats, rendering looks impressive. I'm interested in technical details like DSP/GPU split/performance difference. Is that code DSP specific, memory write bug workaround?:     loadw   (r1),r0    not   r0    rorq   #16,r0    storew   r0,(r1) Edited May 13 by Cyprian 1 Quote Link to comment Share on other sites More sharing options...

It is only run by the GPU.  loadw => get timer value => high word == 0 not r0 => get real value (timer counts down !) and set high word to 0xffff rorq #16,r0 => get $ffff down storew r0,(r1) => reinit down counter  Edited May 13 by 42bs Quote Link to comment Share on other sites More sharing options...
