3D Canvas is a real-time, 3D-modeling and -animation tool that incorporates a drag-and-drop approach. Complex models can be constructed from simple 3D primitives or created using 3D Canvas´s object-building tools. Creating an animated scene is as simple as positioning the objects within your scene for each point in time in your animation. 3D Canvas will ensure the resulting animation runs smoothly.
CoCreate OneSpace Modeling Personal Edition (PE) is the world's first free 3D CAD software which follows a Dynamic Modeling based approach. Easily downloaded from the Web, it offers the power of standard CoCreate OneSpace Modeling 3D CAD system allowing you to create assemblies up to 60 parts. This software stands apart from any other CAD system you may have tried or are currently using. Built on a history-free foundation, this Dynamic Modeling based 3D CAD software helps you design products, create associative drawings and analyze design ideas quickly — it's like getting Microsoft Office-like productivity from a CAD system.
Ayam is a free 3D modelling environment for the RenderMan interface.
* RIB (RenderMan Interface Bytestream) export and import.
* Support for NURBS curves and (trimmed) NURBS surfaces, Boxes, Quadrics (Sphere, Disk, Cylinder, Cone, Hyperboloid, Paraboloid, and Torus), CSG, MetaBalls, Patch Meshes, Polygonal Meshes, and Subdivision Surfaces.
Blender, the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback.
Blender has proven to be an extremely fast and versatile design instrument. The software has a personal touch, offering a unique approach to the world of Three Dimensions. Use it to create TV commercials, to make technical visualizations, business graphics, to do some morphing, or design user interfaces. You can easy build and manage complex environments. The renderer is versatile and extremely fast. All basic animation principles (curves & keys) are well implemented.
Google SketchUp is a 3D modeling software tool that’s easy to learn, simple to use, and lets you place your models in Google Earth. Are you remodeling a kitchen, landscaping your back yard or adding a deck to your home? Google SketchUp makes it faster, easier and a lot more fun. From simple to complex, from conceptual to realistic, Google SketchUp helps you see your vision before you build it.
