more gears, fast

4 gears

I updated the involute (curved teeth), helical gear generation procedure to use Extrusion rather than IndexedFaceSets. Extrusion automatically supports the back and front faces of the gears, and a smooth appearance by producing a mesh with points shared by triangles. So the logo code could be streamlined and therefore is now much faster generating gears.

Palm tree

This is a simple design and visualisation of a palm tree.  The palm leaves are borrowed from a previous blog. The new part is the tree trunk, which is an EXTRUSION object. Before the inclusion of EXTRUSION in VRMath2 Editor, tree stems or branches may be just cylinders. Using EXTRUSION, more irregular tree trunks can be achieved.

Extrusion star

This is another test of using EXTRUSION object, perhaps a much easier test than previously on gears. In one of the Challenges, I was hoping some one can use simple geometry of pentagon to create a 3D star. It turned out EXTRUSION can achieve this quite easily.

Extrusion helical gears

I recently just included Extrusion object into VRMath2 Editor and started to experiment its applications in creating 3D objects. It is quite easy to use Extrusion to create Spur Gears, but here I am showing how it can be used to created Helical Gears.

general smoothness

smooth gear

Getting gears to appear smooth by explicitly assigning indices to the generated facets got me thinking in more detail of how to accomplish this result in general, for any facets drawn in face mode by turtle graphics.
