A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point. This distance r is known as the radius of the sphere. The maximum straight distance through the sphere is known as the diameter of the sphere. It passes through the center and is thus twice the radius. In higher mathematics, a careful distinction is made between the sphere (a two-dimensional spherical surface embedded in three-dimensional Euclidean space) and the ball (the three-dimensional interior of a sphere). As defined in physics, a sphere is an object (usually idealized for the sake of simplicity) capable of colliding or stacking with other objects which occupy space. From Wikipedia under the

Q. I have a tetrahedral mesh of a sphere, if I increase the volume of the sphere, like by k, what would be the new coordinates of the vertices of tetradera in the sphere? (centroid of the sphere is fixed) Asked by Jery A - Mon Apr 27 00:30:47 2009 - - 1 Answers - 0 Comments A. volume of cube = (4/3) pi r ^ 3 Multiplying the volume by factor M would multiply the coordinates on the sphere by M^(1/3) Answered by Hk - Mon Apr 27 00:39:49 2009 From Yahoo Answer Search: "Sphere" |
