Hi there,

Just wanted to let you all know about the implementation of CSG routines in DeleD. I've written a technical design and created a environment to test it. I'm using a wall-like cube with a cylinder to test the union, intersection and subtraction (carve) operators. All polygons have unique colors to see how they line up. Here are the initial results:





I'm happy to report that this proof of concept is a fact. Smile There's still lots of things to do, like designing a GUI, removing memoryleaks, getting uv-coords into the whole thing, importing all of it into DeleD itself etc etc. But... this is a good start. Smile

Great progress! Is the test object quads and tris or only tris? If quads, i wonder how the difference mesh (and eventual UV mapping) will hold up after conversion to all tris (as required by .mesh and some other formats)?

This is going to be great.

The test objects are made of quads. After applying CSG, most quads are split resulting in tris and multisided polygons. I still have to get UV coords into all this meaning that when a polygon gets split, I need to calculate new UV coords for all material-layers as used by the polygon. So lots of work to be done yet...

I still think i will use inset & extrude,a lot less polys Wink
(but a great adition to DeleD Very Happy )

Inset and extrude are great, but can only be applied in a certain number of cases. How about pushing a cube through a cylinder? Could that be done with inset and extrude? Wink

I've imported my CSG routines into DeleD, implemented a userinterface (right under the Low Polygon commands) and got the whole thing working now. Here's a wall-like cube with 2 cubes and a cylinder subtracted from it + another cube united with it. Smile



I still have to work on a number of things but sofar it's looking promising. Very Happy

Btw, the whole geometry was made in less than a minute. Dave, are you up to a challenge? Wink

I notice that this is implemented in DeledPRO 1.22 in the screenshot.
Is this going to be a PRO only feature ?

cheers

Union = LITE
Union, Subtract, Intersect = PRO Smile
