3D printing

[Joshua Hunt]

Hello! I am new to the coding language and was wondering if there was away to 3D print what I/students code. I looked in the discussion but I have not seen anything so I apologize if I missed something

[Shriram Krishnamurthi]

Sorry, what does "3D print" mean?

Being able to model and then use a 3D printer to print the object out

Ah, I see. That's not something Pyret is designed for right now.

As Shriram said, Pyret (and wescheme.org) doesn't do 3d graphics, so it doesn't produce anything you could 3d print.

This fall I am going to try applying circles of evaluation to doing *simple* 3d graphics in Scheme using an environment called libfive Studio.

https://libfive.com/examples/

Where this code:

difference(

difference(sphere(9),

torus(8, 5, [0, 0, 0])),

cylinder(2, 20, [0,0,-10]))

Produces this bead (difference "subtracts" the second shape from the first):

Which can be exported as an .stl file and printed.

There are also Python bindings, so theoretically an easy transition from Pyret.

This is not an official Bootstrap project, and a spectacular faceplant is quite possible, but I'll let the team know if it works and share the materials (I still have to write up all the contracts, etc).

I see thank you for the help. Is this a something you may add in the future?

We have no real plans for it. It's a really niche thing, and people are likely to want to use specialized 3D-printing tools instead. To be honest it's a bit difficult for me to see what Pyret really has to contribute here!

[Tom Hoffman]

Just to be clear -- the distinction is between 2d and 3d graphics, not printing as such.  

Pyret generates 2d graphics, and you can print those out in a 2d (regular, paper) printer.

If you have a program or programming environment that outputs 3d graphics in a standard format, you should be able to use a slicer which works with your printer to create 3d prints.
