Particle Based

Caoimhe McCarthy

This pproject demonstrates the generation of a Houdini Digital Asset for ivy growth. This procedural tool can generate a variety of different scenes based on user defined parameter values. The ivy is generated using a sort of particle based method first introduced in 1985 by Reeves and Blau (1985). Using this as the basis for the growth algorithm, the HDA also simulates external tropisms such as gravitropism and phototropism. Along with the ability to automatically generate ivy, this tool allows the user the more stylistic approach of drawing ivy directly onto the environment geometry. This highly art-directable procedural tool demonstrates an easy way to generate climbing ivy.
