About TurtleBlocks3D

Turtle Blocks 3D is an extension of Turtle Blocks into three dimensions. In addition to moving the turtle on a plane, the turtle can be moved in a three-dimensional Cartesian space.

All of the features from Turtle Blocks 2D are present in this version, along with some new ones.

This activity runs in Sugar and also in the GNOME desktop. To run it from GNOME, you will need to clone the repository and then run the executable turtleblocks-3d.py.

Save as wavefront .obj
Use this button to export 3D graphics to '.obj' format. We currently support points, lines, polygons, and color.

Load wavefront.obj
Use this button to import 3D graphics from the .obj file format (used by many 3D modeling tools). When you click the button, a "Choose an object" dialog pops up; from there, select an .obj file from the Sugar Journal or the filesystem.
