Add support for BRep

[dakerfp]

Add support for handling BRep objects.

[pboyer]

A non-trivial request! I've started work on this in the topo branch working from Marti Mantyla's fantastic book, "Introduction to Solid Modeling".

I've already finished BRep splitting, volume/area calcs, tessellation and the core data structures (Face, HalfEdge, Solid). Almost done with booleans... In the first incarnation this will only support planar faces and I'll expand from there.

I removed this from 2.0.0 (upcoming) because it wasn't ready to go yet. I think I might create a separate project to do this, and keep verb focused on NURBS.

Are there any updates on the status of BRep support?

[pboyer]

@jmwright Thanks for asking!

Presently, I'm focused on making verb's NURBS algorithms a lot faster for 2.1.0.

You can find the current state of the BRep work in the topo branch:

https://github.com/pboyer/verb/tree/topo/src/verb/topo

Thus far, I've focused on polyhedral (i.e. planar-faced BReps). I obviously welcome pull requests.

At this point, I think BReps won't come until 3.0.0, which probably won't surface any earlier than Q3 2016.

@pboyer Thanks for the update!

@pboyer Do you announce your releases anywhere?

[pboyer]

@jmwright Usually on twitter. My handle is @ptrbyr.

Hi any updates on this?

[pboyer]

Not really, but I've got some more free time lately. Maybe it's time to revisit the brep stuff. :D

[stellanhaglund]

That would be quite nice! :)

To be able to let verb read in say a stepfile would it mean that there has to be a solution in verb for all the actions that might be applied in that file?

I think its the tessalation i need the most, is there much missing to use that?

Does the book you mention cover tesselation?

Hi again, I'm interested in tesselation of brep and nurbs to polygons, do you know a good reference where I can learn this? I bought the book from martti mäntylä but I doesn't seem to cover the tesselation part?
