The growing performance depends strongly on the complexity of your scene. Please consider the possiblity of using simpler proxy geometry for the Ivy Generator. Thus, you have to triangulate your mesh before importing. The current release of the Ivy Generator supports only triangular faces. The import does not work properly - my scene looks somehow cluttered. The current release of the Ivy Generator contains only a basic instruction (see readme.txt).įuture releases will of course have a more detailed manual. Please, visit Is there a manual for this tool?

Here are precompiled versions for Win32, MacOS, and Linux including the source code of this project under the GNU General Public Licence. The ivy generator imports and exports obj+mtl files. This simple scheme reveals that the goal was not to provide a biological simulation of growing ivy but rather a simple approach to producing complex and convincing vegetation that adapts to an existing scene. The ivy grows from one single root following different forces: a primary growth direction (the weighted average of previous growth directions), a random influence, an adhesion force towards other objects, an up-vector imitating the phototropy of plants, and finally gravity. The result is a small tool allowing a virtual ivy to grow in your 3d world.

Fortunately I was able to implement a procedural system so that the ivy would grow by itself.

I was thinking of something complex, filled with vegetation - like trees overgrown with ivy. An Ivy Generator by Thomas Luft University of KonstanzĪ few months ago I was looking for a new sample scene to test watercolor renderings.
