The geometric transformation must be used when you are building a custom mesh convex by convex (see the add_convex() function of mesh): it also defines the kind of convex (triangle, hexahedron, prism, etc..)
GT = gf_geotrans(string name)
General constructor for geotrans objects.

GT = gf_geotrans(string name)
The name argument contains the specification of the geometric transformation
as a string, which may be:
- GT_PK(n,k) :
Transformation on simplexes, dim n
, degree k
.
- GT_QK(n,k) :
Transformation on parallelepipeds, dim n
, degree k
.
- GT_PRISM(n,k) :
Transformation on prisms, dim n
, degree k
.
- GT_PRODUCT(A,B) :
Tensorial product of two transformations.
- GT_LINEAR_PRODUCT(geotrans gt1,geotrans gt2) :
Linear tensorial product of two transformations
