Model a C using BRL-CADBRL-CAD
Status: ClosedTime to complete:
48 hrs
Mentors: Sean
Create an uppercase letter "C" geometry model using BRL-CAD. You can use the mged or archer geometry editor tools or write a script. The model should be roughly 1000mm tall, about 500mm wide, and about 100mm deep. Create it using CSG or other methods, but it cannot be an imported model, polygonal mesh (BOT, NMG), or extruded bitmap (EBM). It should be free of modeling errors (no overlaps, run "rtcheck" to verify). It should have interesting shader properties set (suggest stack+plastic+texture), default shader will not be accepted. Provide the .g geometry file and a 1024x1024 rendering at a "ae 35 25" view to show what it looks like. References:

As you are notified that the initial deadline has just passed and you have only 24 hours to submit your work, I would suggest in case of any trouble you can ask questions here or on our IRC channel. Our IRC address: irc://freenode/brlcad
Best of luck :)

One of the mentors has sent this task back for more work. Talk to the mentor(s) assigned to this task to satisfy the requirements needed to complete this task, submit your work again and mark the task as complete once you re-submit your work.
So that's an interesting combination of colors on the checker shader, but you can't see the shape. Try using the stack shader with checker and plastic.

Hopefully this is better. Certainly easier to see. Let me know if you would prefer any other changes.
That's still flat. Note that the order you stack shaders matters. You stacked plastic before checker. You need to stack it after.
Assuming you fix that, the next problem is the shape. That doesn't exactly look like a C. A C isn't just half a circle cut in half.

Reworked the model, changed the orientation of the model, and changed the order in which the shaders were applied. Let me know if any further changes should be made.
Thanks,

That's looking much better but you went from too much cut out of the C to too little. Look at the C's in the font on this page even (your "Changes..." for example). Notice how the C is cut around 1:30 and 5:30 on the face of a clock and cut at an angle. You can edit the arb8 you're subtracting from the C and raise/lower the top/bottom face and then move the outside two edges to get a different angle.

Very nice work javamonn! Took a few revisions, but that looks great now.
