Re: [Flightgear-devel] Shader based random trees and improved random objects

Congratulations - it looks fabulous. This is likely based on vertex shaders. This leads me to the question: Does OpenGL offer a software based vertex shading branch like DirectX does? This would allow you to use the same shader code for hardware accelerated trees and - at a reduced level - for sof

Stuart's trees (with Tim's help) are very cool. Here's one more video before I'm done playing with them for the night ... http://www.youtube.com/watch?v=d_VPtzexsg0 Curt. On Jan 22, 2008 7:09 PM, Curtis Olson wrote: > On Jan 22, 2008 7:09 PM, Georg Vollnhals wrote: > > > THIS is incredible.

[Flightgear-devel] Shader based random trees and improved random objects

Hi All, I've been working on a shader-based approach to creating random trees with help from Tim Moore. Here's a screenshot of what I've managed to achieve so far: http://www.nanjika.co.uk/flightgear/forest.jpg A patch which includes both the shader trees and improvements to the random object p
