model_fit_plane()

Vector3< double > model_fit_plane

(

Bmodel *

model

)

Fits a plane through a model.

A plane is fit through the components and the normal calculated from:
    n•p = d
where n is the normal vector, p is a point in the plane, and d is the offset.
Only the first model is fit.

Parameters

*model

model structure.

Returns

Vector3<double> plane normal.

model_generate_from_plane_guide()

Bmodel * model_generate_from_plane_guide	(	Bmodel *	guide,
		double	separation,
		double	sigma
	)

Generates a plane model and fits a plane through it.

Parameters

*guide	model structure.
separation	separation between components for new model.
sigma	smoothness of model.

Returns

Bmodel* new model based on input model.

The principal axes of a planar model are calculated and a new plane model
generated with the given separation between components.
The components of the new model are then adjusted to fit the guide model.
