Q - question

Creeping plants for 3D objects.

A - answer If you want to generate 3D creepers for your buildings or other objects from CAD applications, you can use the free Windows utility Ivy Generator [url verified 6/2007].

This "Ivy generator" asks for several parameters and generates a climbing plant rambling over walls and other surfaces of the loaded 3D model (building, construction, statue, etc.). It generates vegetation with stalks and leafs - including attached materials for rendering.

After loading of your 3D scene (building) double click in the scene to place the ivy root and press Grow. You can stop the growth anytime and press Birth to generate the 3D model (mesh).

Ivy rendering

The input and output formats of the Ivy Generator program are .OBJ files. OBJ files can be directly processed e.g. in Autodesk 3ds max or Autodesk Maya. You can use external tools to convert .OBJ files to/from DWG (e.g. for AutoCAD) - some are even free - e.g. VIP Tip.
