Module type Gg.P

Implemented by all point types.

type t

The type for points.

val dim : int

dim is the dimension of points of type t.

type mh

The type for matrices representing linear transformations of homogenous dim space.

Constructors, accessors and constants

val o : t

o is the point whose coordinates are all zero.


val mid : t -> t -> t

mid p q is the mid point (p + q)/2.

val tr : mh -> t -> t

tr m p is the affine transform in homogenous dim space of the point p by m.

Note. Since m is supposed to be affine the function ignores the last row of m. p is treated as a finite point (its last coordinate in homogenous space is 1).
