Hi everyone and please forgive me if I lack fundamental knowledge regarding this issue but graphics programming has always been my passion whenever I get the chance.
Now what I'm ultimately trying to do is drawing some clouds in the 3d scene, I'm experimenting with perlin noise from the pixel shader and utilizing a uvw coordinate to generate the values.
I set the pixel shader only for a cube which supposedly will be the clouds but I guess my understanding of the concept is not clear on volume textures, because it only renders the sides and never shows the inside:
Am I doing a viable technique for clouds, is there a better/right way to do this? if this is indeed a practical way what do I need to change to render the whole thing with the inside pixels/texels
