 | | New Primitive - 1-8t0102 1/8 torus, 1-inner Radius, 2-outer radius [DAT]
|
|
Hello, Here is a new proposed primitive. It has an inner radius of 1 ldu, and an outer radius of 2 ldu. I have a spreadsheet that made this, so I can generate just about any size needed for a standard 16 point circle. I have been working on a (...)

However, if there is a general feeling that a sphere primitive with an even distibution of triangles is a far better option, I'm prepaired to withdraw my submission (made August 22th) in favour for a 4 decimal places version the primitive (...)
