Hi, I'm experimenting with PNGs with transparency and was wondering... is it possible that a png image can't be drawn properly "behind" another png image when it is located in the right half of the screen?

here's the main part of my code

for(int x=0;x<20;x++){
for(int z=0;z<20;z++){
for(int y=0;y<20;y++){
pushMatrix();
translate(x*dil+(sd),z*dil+(sin(radians(sd2)))*100,y*dil);
rotate(radians(random(0,360)));
image(a,0,0,30,30);
popMatrix();}}}

I tried removing the rotate() & changing the for loops order xyz xzy ... but nothing seems to work.. did I miss something.. or is it just like that..

I'm new to processing and don't really know much, but, have you tried enabling/disabling smooth() to see if that works? Sometimes pings have lines in them and don't display well, there some known issues that are being worked on.

Also, have you tried changing your graphics renderers, e.g. P2D, P3D, OpenGL? Some renderers seem to do better than others.

Ok, I tried changing from OPENGL to P3D and it worked. OPENGL, why are you so frustrating??!!..

Might that could help.

it's more likely to be a drawing order thing. things drawn later appear on top of the earlier things. and the transparency isn't perfect.

there is a hint that may help: http://processing.org/reference/hint_.html (Enable Depth Sort). or, yes, use opengl.
