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.

Where to get TurtleBlocks3D

The TurtleBlocks3D activity is available for download from the Sugar Activity Library: TurtleBlocks3D

The source code is available here.

Toolbars

In this section you will find the description of those toolbar items that are unique features of the 3D version of Turtle Blocks. For information about other toolbar items, please refer to Turtle Blocks wiki page.

You can save the 3D objects you create in TurtleBlocks3D as .obj files and you can load .obj files generated from other programs, such as Blender.

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.

Example .obj

It is 3D, So you can also choose where to look from, With the Camera-position option you can choose top, front, left, right, top-left and top-right camera positions!

Turtle Palette

These blocks are used to control the movements of the turtle.

forward: move turtle forward
back: move turtle backward
clean: clear the screen and position the turtle in the center of the screen, pen down, color red, heading 0
left: rotate turtle counterclockwise
right: rotate turtle clockwise
set xyz: set turtle's x,y,z position (0,0,0) is the center of the screen *
set camera xyz: set camera's x,y,z position *
set heading: set turtle heading
set roll: set turtle's roll *
set pitch: set turtle's pitch *
xcor: holds current x-coordinate value of the turtle (can be used in place of a number block)
ycor: holds current y-coordinate value of the turtle (can be used in place of a number block)
zcor: holds current z-coordinate value of the turtle (can be used in place of a number block) *
get heading: heading: holds current heading value of the turtle
get roll: heading: holds current roll value of the turtle (can be used in place of a number block) *
get pitch: heading: holds current pitch value of the turtle (can be used in place of a number block) *

Items marked with * are the options that only exist in Turtle Blocks 3D.

Modifying TurtleBlocks3D

We plan to add texture mapping.
Rewrite a JS Version of the activity
