3D Model Maker lets you create virtual 3D models in your computer. You can create anything your imagination can think of. (Not limited to simple cubes or blocks like some apps!) It uses meshes of polygons just like they used in Toy Story.It uses the 3DS file format which is compatible with lots of professional software like Autodesk 3D Studio, Maya, AutoCAD and Blender. This means you can create your models on the move on your tablet or PC and import them later into the 3D package of your choice.Use tools like "extrude", "subdivide", "smooth", "pull" and many more to create your 3D objects. Move the individual vertices around or move select multiple vertices with the box select tool.Paint the faces different colors. Rotate the 3D shapes at any angle or choose from a list of views. »

DeleD is a 3D modeler and level-editor combined into one. It focuses at game development and is specifically designed to create static objects/worlds. Other areas in which you can put DeleD to good use are, for example, educational services, webdesign, prototyping and image creation.
