When looking at my blog stats, the most popular post by far is the old Ripple effect I did some time ago, which was based on an old demoscene trick. For a while, I’ve wanted to do a more physically correct version based on shallow water equations. Since the watercolour effect I did was based…
The last 2 months, I’ve been investing 99% of my free time into the next iteration of Farbe, turning it into a real Flex-based image editing tool simulating natural media. Although there’s nothing of the application itself that I can show yet, today I created another small proof of concept for it that I can…
Something I’ve been thinking about doing for a long time is imitating real artistic media, in particular watercolours. Not because I’m an avid watercolour painter (last time I’ve touched them was in kindergarten), but because I think it’s an interesting dynamic. Since it is mainly fluid dynamics, the idea resurfaced after my previous fluid sims.…
If you’ve played any video games the past few years, you’ve definately seen the HDR (High Dynamic Range) effect. Creating a more brilliant colour spectrum, it’s both popular in photography and 3D rendering. In games it typically enhances the brighter areas and makes light spill over into darker areas (the so called light blooming effect).…
The third pass at smoke/fluids simulation again looks quite different from the previous two attempts, but this time it’s stable both when keeping still as while moving. Not surprisingly, as the current approach is more like Stam‘s fluid solver. The downside is that it’s much less processor-friendly: every new step (adding forces, diffusion, advection, updating boundaries, …)…
