Topologic is a simple renderer for certain higher-dimensional geometric primitives and some regular 3D shapes. The idea is to make it easy for students of certain higher-dimensional maths and physics topics to visualize the typical primitives in those fields and get a grasp for the topic.
Instavue extracts the Instaviz diagrams from the user's iPhone or iPod Touch backups. The user can then choose to print the diagrams or export them to any of these vector and bitmap formats: BMP, EPS, GIF, Graphviz, JPEG, PNG, PostScript, SVG, TIFF, Visio VDX, or VML. Mac users can also export to these additional formats: JPEG2000, OpenEXR, Photoshop, PDF, Quickdraw, Silicon Graphics or TGA. Windows users can also export to the EMF (Enhanced Metafile) format.
