iTracer CAD 3D modeling
Fabio Policarpo has introduced iTracer, an iPhone app allowing 3D modeling and rendering, according to Architosh. Using many tools found in full-blown modeling software, designs are modeled in two dimensions with a curve editor, allowing tuning and addition of vertices. Extrusion and revolution surfaces can be used for 3D modeling. Scaling, panning, rotating, or translating adjustments are made with the multi-touch interface.
The integrated material editor offers refraction, opacity, self illumination, and diffuse or specular components. Shadows can be cast from different light sources, with recognition of transparency. Procedural objects are supported for quicker rendering and added accuracy. The 3D renderings can be built from any viewpoint, and saved to the phone memory for future reference.
iTracer for the iPhone is availabe from iTunes for $4, with any future updates included for free. The developer is already planning on improving the camera, adding photo backgrounds that reflect/refract through objects, and an undo system.
