Topic awaiting preservation: Real-time raytracing: winamp 5 visualization preset

Made by me!



If you use Winamp 5, drop http://www.slimeland.com/misc/raytraced.avs into a subdirectory of Winamp/Plugins/avs, launch the visualizer in winamp via Right click -> visualization -> start/stop plugin, and then right click in the visualization window and select the preset in the subfolder you put it in.

I just got around to downloading Winamp 5 I'm really impressed with the capabilities that the AVS has now. Not to mention the player itself =)


 

How does it perform in the memory-hogging field? I'm still using ver2 simply because it works, and I don't need any extra's.

well... it'ns not that bad. My winamp 5 consumes 9.5 megs right now.
Turning on the (nice) slime visualisation increases it by 2 megs.

uhh... I like that ball...

man thats sweet. maybe you could add some ozone style to it? like adding a font which says "ozoneasylum" or use the oa colorsheme. just some ideas.
however, excellent work! love it

amazing!
so how did you get the raytracing code in there?
all by hand or did you use that winamp editor?

I have a gig of memory so I rarely worry about that. =) But Windows reports that my full version of winamp is taking 18.2 MB. Er, then I started a song and it jumped to 20 MB and then down to 11 MB. So, yeah, it's in the teens. =)

could use a reflective cylinder or sphere, around the scene, which would reflect and multiply the central sphere

A possibility, but probably not worth the work. Mostly I'm worried about recursion, since I'm not actually using functions here. Iteration isn't easy to do with this, either. Just the ray-sphere intersection is already a bit of a hassle. Control structures are difficult to work with in the AVS language.

adaptive sub sampling

There actually isn't any adaptive sampling; I tell the AVS a grid size to use (I used 70 x 70) and it does my raytracing algorithm for each spot on the grid, and interpolates between the values. You can reduce the grid size in the AVS editor and see how strange the sphere's edges become.

I don't think there's any way to do it without the AVS editor. But there was definitely some coding involved.

The idea is to render the textures to buffers, and then use dynamic movement transformations to sample from those textures depending on screen coordinates. The part I had to write was the raytracing algorithm to determine, from an (x,y) screen coordinate, what (u,v) texture coordinate should be drawn.

Then I had to do that twice, once for the sky texture and once for the plane texture.


 

Nice. Ill be adding it to my WinAmp :P

Edit: Not bad - Installed and looks awsome :P Nice job!
