ray trace, with opengl ou P3D,

in Programming Questions • 1 month ago

does somebody know how can i draw every frame, pixel by pixel, and still get a good framerate.

Something similar to ray trace.

My primal quuestion is just how to make some similar to below and still get a good frameRate

Copy code

for(int a = o ; i< width ; i++) {

   for(int i = o ; i< height ; a++) {

   stroke(255,0,0);

   point(a,i);

      }

}

It is very difficult to get a decent speed with Ray Tracing in general and Processing is not an exception. You're going to want to start with P2D and pixels[] (instead of point).

Edit: I am not sure why you mentioned P3D, do you know how Ray Tracing works?

but do u know any program that i can do something like take?.

i think that if u y«tell to run the pixel code part with the gpu instade of the cpu will run alot faster.

but can java or processing do that.

if not can u tell me were can do that?
