Sorry for the delay. I hope to submit more, but haven’t had time.
One of the students at SCAD(Michael Raleigh: Check out his video) had asked me about alternative ways to grow plants against geometry. There are multiple ways to approach this, but I had suggested using particles to create curves to interact with the geometry. Then off the particle curves L-systems could be instanced or what have you. This led me to create a sample file that illustrates multiple ways to create particle curves/trails.
The file is somewhat a tutorial, so be sure to middle mouse button over nodes to read the comments. Comments may also be read by opening them. Right click on the node and select “Edit Comment” to bring up the editor(easier to read that way).
