Anyone knows that demo? I am quite impressed, but there''s one thing that doesn''t get out of my mind: How the heck do they blur the lines out from the center when they draw the wireframe cubes? I just don''t get how to do that.
Anyone got an idea?

Hi,
I downloaded the demo, but it doesn''t wanna run here. Could you upload a screenshot or something of the effect ?

Sure. I uploaded two shots of the effect here:

So, anyone knows how to do that in realtime?

They may have used an accumulation buffer. Basically, they draw the scene to a backbuffer each frame, without clearing the buffer first. Instead, the color of each pixel in the buffer is faded over a numer of frames to match the background color, before the new frame is drawn. This gives a nice motionblur effect, but it''s pretty slow. OpenGL supports accumulation buffers, not sure about Direct3d.

It doesn''t fade as frames pass by and it''s NOT a motion blur effect. Rather it blurs lines as they get farther away from the center...

Hi,
yeah, that looks pretty cool, but I don''t know how this could be done. Why not just ask Ile or someone else of the Aardbei-dudes ?

Hi,
I guess I found the solution. Just render each frame to a offscreen-surface and then use this surface as the texture again. Now you gotta render some polys to the screen and play around with the uv-coords and it should work. I didn''t try it yet, but in theory it should work.
