Wavelet Turbulence for Fluid Simulation

Appearing in SIGGRAPH 2008.

We present a novel wavelet method for the simulation of fluids at high spatial resolution. The algorithm enables large- and small-scale detail to be edited separately, allowing high-resolution detail to be added as a post-processing step. Instead of solving the Navier-Stokes equations over a highly refined mesh, we use the wavelet decomposition of a low-resolution simulation to determine the location and energy characteristics of missing high-frequency components. We then synthesize these missing components using a novel incompressible turbulence function, and provide a method to maintain the temporal coherence of the resulting structures. There is no linear system to solve, so the method parallelizes trivially and requires only a few auxiliary arrays. The method guarantees that the new frequencies will not interfere with existing frequencies, allowing animators to set up a low resolution simulation quickly and later add details without changing the overall fluid motion.

R870 to spot 2000 shader processors?

[English]
A rumor claims that AMD is aiming for 2000 shader processors with the next high-end card, R870, which should also be a dual-GPU card, meaning 1000 shader processors in each of the 40nm RV870 GPUs.
[/English]
[French]
Une rumeur dit qu’AMD va placer 2000 shader-processors dans son futur haut de gamme, le R870, qui devrait être aussi bi-GPUs (donc 1000 shader-processors par GPU RV870).

3DVIA Challenge – Be the Top Modeler!

Do you think you have 3D modeling skills? 3DVIA is proud to announce its first 3DVIA Challenge – a special bi-monthly contest to prove which of our users has the best 3D modeling skills.

Every other week (or so), we’ll announce a new 3DVIA challenge asking you to submit your best work based upon a set list of guidelines. Each challenge will be different and will have you testing your 3D modeling skills against thousands of other modelers. For our first challenge, we start with a very popular content type on the site…military vehicles under the theme of ” The Military Might”.
