Hello everyone~ I’m trying to render grass, but i find it is very hard to make it real… i found a sample called natrue scene from nvidia but it’s written in c++…does anybody has sample code in jogl + glsl? or a jogl version of nvidia nature scene?
If you want to do a demo, than nvidias nature demo is something to copy. If you want to have something else in your scene, you might want to think of a way to cheat (LOD etc).
Think about it. A small patch of grass is going to burn all the vertex and pixel fill rate you have even with “instancing”.
If this is something you are starting opengl with (sounds like it), its not the best way to get an introduction to opengl.
And finally have you checked out some 3d engines that may have “terrain” models available. Like the java Monkey Engine or its fork (ardor3d IIRC).
Try a nice image of grass with some particle effects for the smoke.
