NAME
model2view_lu - convert model xyz to view coordinates (local units)

SYNOPSIS
DESCRIPTION
The model2view_lu command converts a 3D model-space point (in local units) into 3D view-space coordinates (also in local units). The three arguments x y z are model-space coordinates expressed in the database’s local units.
The conversion pipeline: the input is scaled from local to base units, transformed by the gv_model2view matrix to get normalized view-space coordinates, then scaled by gv_scale × base2local to produce local-unit view-space coordinates. The result is a space-separated 3-element vector.
This differs from m2v_point, which works in normalized view space rather than local-unit view space.
The inverse operation is view2model_lu.
EXAMPLES
Example 1. Convert the model origin to local-unit view coordinates
mged> model2view_lu 0 0 0
Returns the view-space position of the model origin in local units. The result reflects the current view rotation and zoom level.
Example 2. Convert an off-origin model point
mged> model2view_lu 100 0 0
Returns the local-unit view-space coordinates of the model point 100 units along the X axis.
