Leadwerks Gets Balls

The subject of spheres in 3D World Studio has been one of great levity (see here and here) around the Leadwerks community. I spent today finally implementing a CSG sphere primitive. This is a little different from creating a conventional triangle mesh sphere because each face is a single polygon with either three or four sides. Here's my scratch paper that got me through this process:

I'll spare you the mathematics and get right to the good stuff:

This completes the basic primitives, which include boxes, cylinders, cones, wedges, and now spheres. Tomorrow I will get started on compound primitives (arch and tube) as well as smoothing groups.

 

Let the hilarities ensue in the comments below. sleep.png

Just love to see that scratch paper... I have a bunch of those my self smile.png. Also I'm happy to see that your papers ends up in something useful. Mine usually only ends up in the trashcan.

Great! I love to see a new news about 3DWS in LE3D. If I could possibly make a suggestion (of course if this not be a problem) ring torus would be very useful basic (or compound) shape. For example: his severed parts in conjunction with the cylinders are the perfect elements to create pipes and complex pipelines. As we all know, old rusted pipes are very important part of all dark underground tunnels ;-)

I was thinking of having a cylinder and a bend option, but maybe one of the interns can implement a torus like that, too. I can already tell people will use this for some fairly complex modeling.
