Simple geometric IO | |
These functions write geometry to text files, one line per geometric primitive. Each line has the form “x y z” for points or “x y z r” for spheres. We can easily add general dimension support if requested.. Lines beginning with "#" are treated as comments. | |
| void | write_spheres (const Sphere3Ds &vs, base::TextOutput out) |
| Write a set of 3d spheres to a file. More... | |
| Sphere3Ds | read_spheres (base::TextInput input) |
| Read a set of 3d spheres from a file. More... | |
Vector Generators | |
These functions generate vector objects. Some of the methods, those with random in their name, generate a single vector chosen uniformly from the specified domain. Others, the cover methods, generate a set of points distributed (somewhat) evenly over the domain. | |
| template<int D> | |
| VectorD< D > | get_random_vector_in (const SphereD< D > &s) |
| Generate a random vector in a sphere with uniform density. | |

class IMP::algebra::SphereD< D >
Represent a sphere in D-dimensions.
- Note
- This class is a geometric primitive. Also, this class is not not initialized by its default constructor.

The function is currently pretty slow, especially in non-optimized builds. Complain if this bugs you. We might be able to do better, at least in 3D.
Creates at least the requested number of points.
- Note
- This predicates will produce guaranteed correct results if the CGAL library is available (the results will be unreliable if it is not).
