   Creating 3D oval meshes
  Does anybody have an alogorithm to make these? I have methods for making spheres but now I need to make an oval shape that derrives it's height, width and length from the bounding box of a mesh and I have no idea where to start.   
  Not sure if this is what you're going for, but you could always create a sphere and use a matrix to scale it to the needed size in any direction. If nothing else, it's a starting point.   ;  This might help:http://mathworld.wolfram.com/Ellipsoid.htmlhttp://en.wikipedia.org/wiki/Ellipsoid;  I would just use D3DXCreateSphere and run a scaling matrix over it.Dave   ;  The scaling matrix sounds the best to me :) Ellipsoid math is just so confusing.I found those ellipsoid math forumla web pages yesterday and ugh, my head wanted to explode.I've started writing new additions to the sphere code I have so getting to keep the code would be a huge bonus.Thankyou for the input guys.
