So here it is, new demo is out! It’s called Taxesss from Nothing and it was released at Mainparty this year. This demo started as an idea from my good friend and work colleague, ps, who usually watches my experiments in first hand. After watching some of the stuff you can see in my vimeo account, he came out with this piece for a grindcore jazz track from The Lost Gorbachevs. After handing him all the sources, he started building the demo while i was working on my own idea. Well, it turns out Taxesss is out and has been quite well accepted by the alternative parties, and my own project is still waiting to come out.. Hope you enjoy this piece.

You can download the demos from scene.org.

One more ‘hmm’ series experiment.

Motion Blur as a Post Processing Effect.

This is based on an article from GPU Gems 3, which basically takes the motion for each pixel and computes a velocity from the difference with the previous position to sample the rendered scene texture and compute the final color. It works only for camera movement, meaning, if the camera does not move but you have a moving/rotating object in front of you the effect won’t apply.

This two videos shows camera lookat point motion, meaning it randomly looks at different points every second, and the second video shows a camera spinning around a sphere objectwith increasing velocity to reach a maximum blur state. Both are using camera motion as i stated it’s important, anyway, it should give an idea of the effect.

Here is a new experiment. This time Terrain rendering and Countless blades of waving grass.

The terrain is an heightmap loaded from an image and it is textured on gpu based on simple rules like height, slope and steep.

The grass is based on the article “Rendering Countless Blades of Waving Grass” from GPU gems. The animation is per-object, a sin/cos wave makes it flow with the wind.

After getting MD5 files (Doom 3) to load correctly i wanted to make something simple and nice to show the world, so i came up with this. I think i have dreamt of this before.
