xyz_from_q

compas_tno.algorithms.xyz_from_q(q, Pi, Xb, Ci, Cit, Cb, SPLU_D=None)

Calculate coordinates’s xyz the q’s.

Parameters:

qarray [m x 1]

Force densities of all edges.

Piarray [ni x 3]

External forces applied to the free vertices.

Xbarray [nb x 3]

Position of the fixed vertices.

Ciarray [m x ni]

Connectivity matrix on the free vertices

Citarray [ni x m]

Transpose of connectivity matrix on the free vertices

Cbarray [m x nb]

Connectivity matrix on the fixed vertices

SPLU_Dcallable, optional

Sparse LU decomposition of CitQCi to speed up optimisation, by default None

Returns:

Xfreearray [ni x 3]

x, y, z coordinates of the nodes
