soy.scenes.Planar

[ArcRiley]

This class will inherit from soy.scenes.Scene and add a ODE collision plane rendered as a large plane of the same size. It is important to note that the plane is a part of the scene itself, not a body.

The plane faces up in the direction of scene gravity, or in the Y axis if no gravity is used, and will have a size parameter accepting two elements.

The center of the plane will always be (0,0,0) unless a simple property allows otherwise.

The plane will have a .material property for changing the material. A second property may allow the texcoords to be something other that (0.0,0.0,1.0,1.0).

The plane will be a poly grid (triangles, quads, etc) such that specularity and other effects work as expected.

Lastly, a simple example should be written to render spheres on it with one of the spheres controlled by the keyboard, or a similarly basic example of how a plane works.

visual mockup

[ArcRiley]

Here is a mockup for one possible way to render the plane.

In this mockup, 1024 triangle units are rendered with only 16 tri's.

Likewise, 4096 would be rendered with only 19 tri's, 16384 with only 22, 65536 with only 25, 262144 with only 28 tri's, and a whopping 1048576 (> 1 million) with only 31. This pattern can continue to render billions of triangle units with less than 50 triangles.

Obviously the larger triangles (further out) should be rendered first.

Done for Beta-3, but could use some work: * Correct Tex-coord generation * Optimize Vertex / Face generation ( Some Verticies could be used more than once) * Implement Bumpmapping * Allow 'Earthquakes' to be applied
