An update to RhinoGrow is available here: http://www.camnewnham.com/rhinogrow
This update specifically is based around Octane - the ability to generate the scatter matrices without adding any geometry at all to the document - just creating a text document.
This capability will be greatly increased in the next update of Octane for Rhino, which removes the 10,000 limit for .csv files
Check the bottom of the page under heading "Running (Matrix Output)" for instruction/example
Example:
~108,000 blades of grass, each containing either 6 or 8 triangles (12 different blades distorted and oriented 9,000 times each) in a 2m*2m area.
~14mb on the hard drive to store the .csv files
~36mb v-ram used
This was to test individual blades - for best results (vram wise) you're best off making groups of 10-100 blades.
(Note, I'm just using flat diffuse materials - for best results use a realistic SSS material)
Good luck !
