I want to create some 3d objects for importing into Poser. I want to take a black and white image (e.g. a logo) and to extrude the shape. A simple example would be, for example, to convert a black square into a cube. And I want to do this semi-automatically, without the need to use the graphic as a template and then manually draw around it.
I would prefer to do this with cheap (or free) software; and have so far looked at Blender, Adobe Illustrator, Inkscape and AccuTrans 3d.
Accutrans3d appears to do be able to do simple graphics; but tends to crash when huge and complex shaped graphics are used.
Please. Can anyone suggest what software might be available for this task?
Many thanks.
