Model BRL-CAD logo in BRL-CADBRL-CAD
Status: ClosedTime to complete: 72 hrs Mentors: SeanTags:

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, ideally 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.

You are encouraged to discuss and share progress with the developers for interactive feedback.

Ajeet, this is looking good, but you haven't joined the two links together.  The black and pink links need to be put into or made into a region (see the 'r' command) and then those two regions need to be joined together into a single group (see the 'g' command).


Looking at your model, they currently overlap each other, which won't work.  The black and pink portions need to link with each other or otherwise not have any overlaps (run "rtcheck" command). Ask questions if you get confused as this is a difficult concept for most new modelers.

You're method for just subtracting all of shape2.s from shape1.s is not ideal, but it is a technically realistic solution.  Overall, this is a nice model that hopefully someone will be able to build upon.
