The primitives are distributed uniformly across two dimensions but not across the third. In general then would uniform grids be implemented as a 2d grid rather than a 3d grid?

I am also curious about the z axis, maybe we can make it non-uniform?

@atarng Yes, and amazingly it's done in real time! See this link

@aylu, @Isaaz: Yeah, in fact you could do a hybrid. Use a 2D regular grid for XY, and then within each regular grid node store a pointer to a BVH. Lots of possibilities.
Is this grass field rendered?
