Index of values

add v1 v2 returns v1 + v2.

Angles (orientation) of the bones.

Solves a upper triangular system.

Split a movement into small steps of length epsilon.

The directed bones (source, destination, length).

dist_from_point o v p gives the disance between the point p and the line o + k * v.

Applies the constraints.

gauss m b transforms m and b such that m is upper triangular, without changing the set of solutions of m*X=b.

Metaballs smoothness depends on the grid_step.

Parse the skel, starting from the root, in order to get the new bones, topologicaly sorted.

move () returns true if the move is finished.

nearly_zero f tells whether f should be neglected or not.

Get the norm.

Normalize.

Conversion from a rough constraint to a precise one.

print_sys m b displays the system m * x = b in a very verbose way.

print_sys_silhouette m b does as print_sys m b but is more visual.

Scalar product.

solve a b solves any system -- at least it tries.

Get the square of the norm.

sub v1 v2 returns v1 - v2.
