Hi,

I've setup another little Proof of Concept project which implements DeleD's new datastructure. This datastructure provides us with topological information about the 3D objects, allowing us to perform more lowpolygon functions more easily. Like this: here's a cube with it's vertices bevelled.



More lowpoly stuff like merging faces and deleting vertices (hi hpesoj! Very Happy ) will be next!

The new structure is fast too and will also serve as a base for creating high-resolution objects. But that'll be a while. Wink Anyway, just to let you guys in on our progress here.

Wow. That looks awesome. Smile Keep up the good work and you'll have an app that no other app can compare too. Smile

Update: polygons are updated correctly too now.



The new structure is cool. Just have to get used to all this new info being available (and in need of updating when applying nifty little lowpoly commands). Wink

This is going to be one of the coolest and best "extras" in a while. Smile Cool

Small update: bevelling all vertices of the cube multiple times results in a smoothly rounded cube. Smile Note that for testing purposes each polygon has its own color here, so I can determine if all went well. Which is just my way of saying you're looking at programmer's art here. Cool



Next on my list: bevelling edges.

Update: connecting vertices has been implemented. Smile

Nice! Can't wait to test it out. Cool

Update: deleting vertices has been implemented (except for a few checks here and there though Wink).

Question: should the Delete Vertex function create new polygons as needed or just delete the vertex and that's it? For example, if you delete a vertex of a cube, should a triangular polygon using the vertices that are adjacent to the deleted vertex be created or not? Note that this does not apply in all cases (for example when a vertex is shared by just 2 edges).

Yes, that is a definite Smile. It'd be kind of like bevelling to the maximum amount (given that all the attached edges are the same length). People can delete the edges created if they don't want them.

Wouldn't deleting a vertice without filling it with a tri leave a hole?? Laughing (semi serious. I have no clue)

Yes, it would leave a hole indeed as you can see:



I think I will allow to user to specify whether or not to fill such holes with new polygons. Remember, DeleD is a generic modeller, not just a solid modeller. Wink

Update: deleting polygons while maintaining the integrity of the datastructure has been implemented.
