New raytraced shadows demo
Monday, August 30, 2004 | Permalink

Another demo to waste your precious time on.
Kicking around those balls, oh man, that's hours of fun!

Enjoy!

2004-08-31: The demo should now work properly on nVidia cards too.

Another amazing demo by humus!

Oh man, those raytraced shadows and environment looks awesome, And kicking around the balls is quite fun. it's also fun to watch the ball's shadows dance around the floor/wall, and watch every shadow cast back upon the object casting the shadow and onto it's environment, but these are soft shadows not ugly hard. ^_^

Also I did notice that little visible light source in the room.

Keep up the good work, Humus!

Oh, and I get 60FPS solid @ 1024x768.

For some reason I'm getting no shadow from the balls on the floor or the walls.

nice, 110 fps throughout

is it really raytraced, though? is that what softshadowing means? i don't think it does...

No shadows on my 5950 either. ATI whore!

This is only really meant for simple objects such as spheres. It doesn't apply to complex models. I'm thinking of writing a raytracing demo for more complex shapes, but it will likely be slower than shadow mapping and stencil shadows and still only be hard shadows.

Spiff,
set desktop bitdepth to 32 or use fullscreen.

iztok,
being raytraced have nothing to do with soft shadows. It's raytraced because it takes a list of objects and computes visibility by checking whether the line from the fragment to the light intersects a sphere.
