GPUerror – propagation of error on a GPU revealing colorful structure in volume

By serendipity this visual computing experiment led to a visualization of colorful structures that evolve from the parallel propagation of errors on a graphics processing unit (GPU). We wanted to transfer color values in subsequent volume slices using an OpenCL … Continue reading

DxParticleSound – FFT Particle Sound Spectrum

This experiments deals with music visualization. The goal was to create as many concentric circles with radius and different color that represented a specific musical frequency, from the lowest frequency (radius = 0, color = blue) at the highest frequency … Continue reading

CUDA experiment II – cell grid kernel

Experimental application in C# using CUDA for parallel computation. The grid is quite small sized, but the GPU does it’s work: 512×512 pixels are computed by a cell formula that calculates the difference between the average neighborhood and the current cell’s value. Continue reading

CUDA experiment I – sinus kernel

Experimental application in C# using CUDA for parallel computation. The grid is quite small sized, but the GPU does it’s work: 512×512 pixels are calculated by various sinus functions that use their output as input while cycling through time. Continue reading
