Totally Tubular

Today I implemented the last two compound primitives. Tubes are the same as in 3D World Studio, with parameters for the number of segments and thickness. Since the Leadwerks3D editor supports smooth groups, another new compound primitive has been added. A torus is a "donut" shape. These can be used to make curved pipes and other things. Here are the two compound primitives, side by side:
Smooth groups and new primitives in Leadwerks3D allow you to create new kinds of geometry which were traditionally not possible with CSG editing:
An interesting case occurs when a torus' cross-sectional radius exceeds the radius of the ring. At this point the shape folds in on itself, eventually degenerating into a sphere. To prevent this from occurring, the creation function automatically adjusts the cross-sectional radius, as shown in the image below:
