How Mesh Generation Can Enhance Design Process

Simulation Technique With CFD Meshing

Design With 3D Mesh Generation Software

Finally got this working! This is what I had to go through:

Split the hexagons into islands

Find the islands’ edges (including holes)

Find which of the edges is the outer one (easy, the longest one) 

Group outer edges with their holes (had to use Shamos-Hoey algorithm for line intersection to see if holes were really inside of the outer edge)

Order the edges correctly (outer edge is counter-clockwise and holes are clockwise)

And finally I used PolyPartition to triangulate every island and turned the result into a mesh.

6 steps are not that bad, but I had so trouble with every single one of them @_@. Even PolyPartition, which completely saved me from having to do the actual triangulation, has an awful documentation. I’m considering sending a pull request to update the docs but I gotta get over my anxiety first :p

Main Development Tools and Interfaces

The HUB Studio team uses technologies normally used by game developers, to create interactive modeling systems that present scientific data and scenarios... for users to experiment with a range of variables and see the consequences of their decisions.

In the case of FUTURE FRUIT, we have created a 3D Interactive modeling system for the creation of new fruits based on fruit development biology.

Yanko Oliveira’s Procedural Characters

Let’s get technical. You might remember Yanko Oliveira’s procedurally generated fairy chess, X, a Game of Y Z. Since then, Yanko’s been blogging about some procedural generation projects, including about the chess game and the thing I’m here to talk about this week: generating seamless character meshes.

A demon summoning prototype needs procedurally generated demons to summon, so Yanko has been working on procedurally generated characters. After a first pass in part one to generate the basic mesh and shader, there was a problem getting the modular mash pieces to join seamlessly. Yanko’s got a solution for that now, with a good walkthrough of the thought process that lead there and some Unity code illustrating some of the details.

Of course, now Yanko’s got to figure out how to rig and animate the characters. If you want to follow along, find some ideas for generating your own 3D characters, or have some suggestions for Yanko, I suggest you check it out:

ProcJam is coming, and that probably means that there are a bunch of you who are trying to figure out how to create meshes in Unity from scratch. 

Well, this video should help with that. While it is specifically focused on extruding a shape along a spline to create a new mesh, many of the technical details are important considerations for creating any mesh in Unity.

This stuff is also useful for people who aren’t using Unity, though some of the technical details will be different if you use, say, a right-handed environment.
