Art-directing procedural vegetation in Houdini using a space colonization algorithm
Vegetation modelling plays a key role in shots composition. Achieving a believable and nature-like result has proven to be a tedious and time consuming task for artists. To overcome this issue we present a Houdini tool for trees modelling. Through specifying different parameters' values the tool will generate a variety of tree shapes. Tree structures are achieved using the space colonization algorithm by Runions et al (2007). Model parameters are directly mapped onto visual characteristics and offer an appropriate control over the silhouette and branching structure. This project shows that the toolset can produce a reasonable variety of trees.
