I've got a collection of 10000 - 1 spheres, and I need to find the ones farthest apart.
One simple way to do this is to simply compare all the spheres to each other and store the biggest distance, but this feels like a real resource hog of an algorithm...

Could you perhaps store these spheres in a BSP Tree ? If that's acceptable, then you could start by looking for nodes of the tree containing spheres which are furthest apart.

I want to draw many spheres (~100k) using OpenGL. So far, I'm doing something like
for (int i=0; i<pnum; i++){ glPushMatrix(); glTranslatef(bpos[i].x, bpos[i].y, bpos[i].z); glCallList(DListSPHERE); glPopMatrix(); }
Before using proper spheres, I used...

If you draw ~100k spheres, you might want to consider raycasting them instead of using polygon and a fragment shader to duplicate the effect of a rendered sphere without the actual sphere geometry.

I've seen well-textured balls, planets, and other spherical objects in couple of games, last time in UFO: aftermath. If you just splatter a texture into latitude/longditude as u and w -coordinates you'll get lots of ugly texture distortion to poles.
I...

If you're of the effects you are mentioning.
Lat/lon "spheres" distort by definition.
On a sphere without any poles that distort the texture.

You could then use.
If the resulting line segments intersect the spheres, if the distance is less, that means the spheres collide before this moment.
Location and end location of each sphere.

I have a box filled with (randomly generated) points. On these points i want to create spheres with a constant radius. I can do so by the 'create a sphere' method, but I can't select more than one point. Since I have over a hundred points in my box it...

The discovery of mysterious, blue, gelatinous spheres in an English backyard has captivated the imagination of scientists and the public alike. What the heck are the spheres? And where did they come from?
