Jose, the author of the images and videos above, explains in his blog:
project arose from a conversation with my friend Gino, who is currently working on Medical Visualization, about the difficulty for an artist to create growing structures such as veins -let alone animate them- and how to make them look organic, and therefore irregular and adapted to the surrounding they grow upon.
I decided to tackle the problem, and the first approach that came to my mind were L-Systems, which have proven useful for modelling vegetation. There are two restrictions, however, which discouraged me from taking this approach:
- We should be able to bind the growing of the structures to a surface, and therefore the growth needs to be context aware.
- We need to be able to direct the growth by specifying the areas the structure is allowed to occupy.
Doing some research I ended up taking the approach described in the paper Modeling trees with a space colonization algorithm, listed in Algorithmic Botany, which perfectly suits the aforementioned requirements.
