Local to global coordinate system
Jan 08, 2014 Converting from global to local coordinates (and vice versa) Vertax 2: Local Axis 1 is aligned with the longitudinal axis of the beam, from node 1 to node 2. Axis 2 is perpendicular to Axis 1 and parallel to the XZ plane, so the Y axis is in effect treated as vertical. Axis 3 completes the orthogonal systemTo properly understand the difference between global and local axis and their use you should be first conversant with the topic transformation of coordinate system local to global coordinate system
Where (x, y) are the local coordinates of the global point (X, Y) and \theta is the orientation of the local system relative to the global system. 1 Answer 1. This transformation can be described as the multiplication of a vector by a matrix. This matrix is a rotation matrix scaled by (X, Y).
Convert two vectors in global coordinates into two vectors in global coordinates using the global2local function. Then convert them back to local coordinates using the local2global function. Start with two vectors in global coordinates, (0, 1, 0) and (1, 1, 1). The local coordinate origins are (1, 5, 2) and (4, 5, 7). Global coordinate system in STARTPROF and positive directions of forces, moments, linear displacement and rotation angles. Local Coordinate System. Support loads, node displacement, expansion joint deformation and internal forces can be model in local coordinates, Xm, Ym, Zm, connected to element axes (fig. 2).local to global coordinate system The global coordinate system describes the arena in which your radar or sonar simulation takes place. Within this arena, you can place radar or sonar transmitters and receivers, and targets. These objects can be either stationary and moving. You specify the location and motion of these objects in global coordinates.
