reference/intuition spheres/ellipsoids #45

Closed hududed closed 2 years ago

hududed commented 2 years ago

not an issue but some questions. What's the rationale behind the +1 in diameter = (radius*2) + 1 in sphere generation? Is it just simplifying the for loop index? Also, how would one extend this to an ellipsoid?

Thanks for your questions! The origin point for sphere generation corresponds to a single voxel at the center of the sphere. The +1 in the diameter calculation makes the diameter in voxels an odd number so that there will always be a center voxel for the sphere.

Ellipsoid generation is very similar, and I have added an example ellipsoid generation function to the primitives file (#46).
