*This is for the CE* (At least, I programmed it for and on the CE)

I've been working on this little sub-project (It's part of a larger thing), but have hit a roadblock. I need to be able to fill in the sides with a single color, and I need it to be somewhat fast. It should also cover up the edges that should be on the back. I'm thinking to use flood fill, but that is not exactly a fast way of doing it. I split the code into several programs for ease-of-development.

Sets the current object being drawn to a cube.

prgmOBJCUBE

Sets the current object to a triangular prism

prgmOBJTRIP

Sets the current object to a tetrahedron

prgmOBJTETR

Lets you move independently of the object.

prgmMOVE

Scaling, used for ‘movement’ on the z axis.

prgmSCALE3D

Translates the object, but interferes with rotation.

prgmTRANSL8

Draws the object.

prgmDRAW3D

Helpful info:

[A] is the list of Vertices, and [B] is the list of edges. A ‘1’ in [B] would correspond to the first row/vertex, a ‘2’ for the second, and so on.

Rotates, in 3 dimensions.

prgmROTATE:

Renders, and lets you interact:

prgmRENDER3D

Renders and slowly rotates the object (I’m really inspired by gLib's screenshots)

prgmROTATE3D

With my luck, I missed a program, but I need help

Most of the changes would be in DRAW3D, presumably, as that is where everything (so far) is drawn.

Controls (for RENDER3D):

Use the numberpad to rotate. 8 and 2 rotate on the ‘y’ axis, 4 and 6 rotate on the ‘x’ axis.

Use [2nd] to zoom in, [alpha] to zoom out (move closer and further)

Use [prgm] to move up, [sin] to move left, [tan] to move right, and [)] to move down.

I think that’s it.

EDIT: No it isn't.

Instructions to run:

Press these exact buttons:

[zoom][6][zoom][5][prgm]

Then you can run the program (either RENDER3D or ROTATE3D). Be sure to change prgmOBJ to the selected shape before running!
