Description :
General function for querying information about geometric transformations objects.
Command list :
d = gf_geotrans_get(geotrans GT, 'dim')Get the dimension of the geotrans.
This is the dimension of the source space, i.e. the dimension of the reference convex.
b = gf_geotrans_get(geotrans GT, 'is_linear')Return 0 if the geotrans is not linear.
n = gf_geotrans_get(geotrans GT, 'nbpts')Return the number of points of the geotrans.
P = gf_geotrans_get(geotrans GT, 'pts')Return the reference convex points of the geotrans.
The points are stored in the columns of the output matrix.
N = gf_geotrans_get(geotrans GT, 'normals')Get the normals for each face of the reference convex of the geotrans.
The normals are stored in the columns of the output matrix.
Pt = gf_geotrans_get(geotrans GT, 'transform',mat G, mat Pr)Apply the geotrans to a set of points.
<literal>G</literal> is the set of vertices of the real convex, <literal>Pr</literal> is the set of points (in the reference convex) that are to be transformed. The corresponding set of points in the real convex is returned.
s = gf_geotrans_get(geotrans GT, 'char')Output a (unique) string representation of the geotrans.
This can be used to perform comparisons between two different geotrans objects.
gf_geotrans_get(geotrans GT, 'display')displays a short summary for a geotrans object.
