Media Files==== Plant rendering notes and links ==== (Let me know if this needs to be moved - dg) === Offline rendering === == xfrog == Greenworks organic software: [[http://www.xfrogdownloads.com/]] == gen3 == script for blender > http://www.geocities.com.nyud.net:8080/bgen3/ == Harry Potter 3 - Whomping willow == Done entirely with implicit surfaces to deal with the [[http://en.wikipedia.org/wiki/Fillet_(mechanics)|filleting]] problem. {{http://www.pawfal.org/dave/images/whomp2.jpg}} Very slow to compute, of course - though it might be possible to use some implicit surface mesh calculation, especially if it can be done offline occasionally, and procedurally skinned to a skeleton. === Online rendering === == Autumn == One of my lsystem attempts in fluxus - a very stylistic approach (all right angles). Trees are built out of cube primitives for an artificial life simulation, in isometric projection: {{http://farm4.static.flickr.com/3003/2663638019_4de6239b37.jpg?v=0}} The cubes approach was too slow (for my old graphics card in 2004) I needed to be able to spawn hundreds of trees at a time - they were evolving using mutation errors of data encoded in seeds the trees dropped (and playing music as they grew). I later moved to using camera facing geometry (sprites), textured with faked normals to make them shade according to the lighting to appear cylindrical. With a bit of texturing it looked like this: {{http://farm4.static.flickr.com/3167/2663638025_4b412b3d04.jpg?v=0}} This worked well, and I could render more trees at an acceptable framerate. It might be a good technique for background mass foliage - or low level of detail for distant plants... I think you can do the face forward calculation in a hardware shader these days.
