Model BRL-CAD logo in BRL-CADBRL-CAD

Status: ClosedTime to complete: 100 hrs Mentors: Kesha Shah, DeepakTags: modeling, logo, CAD, design, 3d

The BRL-CAD Logo depicts two interlocked nodes. Modeling the new Logo in BRL-CAD in CSG (without NURBS, without polygons) requires some careful arrangement, but can provide an attractive three dimensional rendering that we can use for a number of purposes..

The output of this task will be a .g file of BRL-CAD logo and a rendered image. The two segments you model MUST be two or more regions hinged together (you can have center pins or not, you decide). This is your opportunity as an artist and 3D magician to come up with an interesting yet faithful interpretation.

Note that there are other logo modeling tasks and yours must start from scratch and be completely original. If we get a hint that yours was based off of or used measurements from some other model, you will be barred.

This command run within MGED should help give you an interesting render:

Congratulations, this task has been completed successfully.

Thanks Michael! Interesting design you came up with there that kind of mirrors the gap between the two pieces on the artistic version. If you render it with ambient occlusion enabled, you even get a nice darkened shadowing effect. Hope you take on some of our other modeling tasks! There are quite a few that will be added later this week.

If you want to get a head start, there will be tasks to model the word "BRL-CAD" in a variety of ways, and to add optical effects for fancy rendering.

Thanks! I was going to render the model with ambient occlusion, but that option alone seemed to cause rt to fail. I'm gonna guess it has to do with the fact that I'm running it in Windows, so I'll make sure to run in a different environment in the future and hope I don't run into the same bug.

And thanks for the information! I'll make sure to look out for those tasks.
