Documentation

This is a class of simple surfaces. The surface is made up polygons.

DVsurface()

Default constructor, makes an empty surface.

DVsurface(LCVMarray<int> &nn, LCVMarray_2D<float> &v, LCVMarray<int> &en, LCVMarray_2D<int> &p)

Constructor with 4 LCVM arrays. nn -- array of node numbers v -- array of nodes en -- array of element numbers p -- array of polygons nn and v must have the same size. Each node in v must have the same number of components. en and p must have the same size. nn must be sorted (increasing).

DVsurface(LCVMarray<int> &nn, LCVMarray_2D<float> &v, LCVMarray_2D<float> &nv, LCVMarray<int> &en, LCVMarray_2D<int> &p)

Constructor with 5 LCVM arrays. nn -- array of node numbers v -- array of nodes nv -- array of normal vectors en -- array of element numbers p -- array of polygons nn, v, and nv must have the same size. Each node in v must have the same number of components. each normal vector in nv must have 3 components. Usually nv are unit vectors. en and p must have the same size. nn must be sorted (increasing).

Destructor

DVsurface& set_data()

Set data to empty surface.

DVsurface& set_data( LCVMarray<int> &nn, LCVMarray_2D<float> &v, LCVMarray<int> &en, LCVMarray_2D<int> &p )

Set data with 4 LCVM arrays. nn -- array of node numbers v -- array of nodes en -- array of element numbers p -- array of polygons nn and v must have the same size. Each node in v must have the same number of components. en and p must have the same size. nn must be sorted (increasing).

DVsurface& set_data(LCVMarray<int> &nn, LCVMarray_2D<float> &v, LCVMarray_2D<float> &nv, LCVMarray<int> &en, LCVMarray_2D<int> &p)

Set data with 5 LCVM arrays. nn -- array of node numbers v -- array of nodes nv -- array of normal vectors en -- array of element numbers p -- array of polygons nn, v, and nv must have the same size. Each node in v must have the same number of components. each normal vector in nv must have 3 components. Usually nv are unit vectors. en and p must have the same size. nn must be sorted (increasing).
