StrandTree - Ice Procedural Tree Generator

Strand TreeAuthor: Fabricio Chamon
Updated April 2014 with a fix by Hans Adrian for Softimage 2014+. Strand Tree is a set of ICE compound nodes that allow the creation of plants and trees. See the author site / the si-community discussion for documentation, example scenes and videos.

Emitters: Emit Branches, Emit Leaves Grow Control: Even distribution grow, Random distribution grow Modifiers: Modify Branch Color by Iteration, Modify Branch Width by Iteration, Modify Particle Size by Iteration, Modify Value by Iteration, Modify Value by Normalized Strand Segment Debug: Debug Iteration Strand Effects: Deform Tree by Curve, Surface Grow Rendering: Tree Visibility Options, Use Geometry Branches Presets: Basic Tree, Pine Tree

Hans' interesting explanation for the Softimage 2014 fix: [..] I moved the »set data« node to outside of »Add point« node on creation. This is because whenever there is a »Add point« node, the custom attribute stored in points may be reset. This was the case with »self.__strandTree_NumBranchesPerIteration«, which was reset to 0. It caused division by 0 in »Even Distribution Grow« node and thus the whole compound does not work. To work around this, we need to set the custom attributes in per Object context, instead, so that those attributes will not reset when there is another »Add point« node.

Available: Softimage ICE Procedural Tree Generator, ICE Procedural Tree - Surface Grow and Tree simulation - wip.

I think this is a case resolved on the mailing list.
