void D3element::Add ( PD3element el )

virtual void D3element::correctNorm	(	double	x0,
		double	y0,
		double	z0
	)		`[virtual]`

Uses ray-shooting to determine the norm and should only be used for externally imported geometrical figures.

From Point (x0, y0, z0) Rays are being shot towards the object in order to determine in which direction the normal vector of each surface is pointing. Generally, all normal vectors can point either to the inside of the object or to the outside of the object. We should make sure that all normal vectors are pointing in the same direction!

A blue color on each outside-surface indicates a correct norm, which means that all normal Vectors are pointing in the same direction. The ions that fly by the electrodes see only the outside-surfaces of the electrodes. If an outside-surface has an incorrect norm, the ion will not be influenced correctly by the surface. This means that all outside-surfaces should be blue!

A red color on at least one outside-surface indicates that at least one normal vector is pointing in a different direction than the others. In this case we need to modify the parameters x0/y0/z0.

Important for the "shooting point" (x0,y0,z0): It must not be in the same plane as one of the surfaces!! Furthermore it must not be inside a geometrical figure!! Otherwise the Ray-Shooting method will not work properly.

Parameters:

x0	x-coordinate of the shooting-point
y0	y-coordinate of the shooting-point
z0	z-coordinate of the shooting-point

virtual void D3element::refine ( double length ) [virtual]

Refines a geometrical figure.

This means that the original geometrical object will be filled with smaller versions of itself. Works good with cubic objects.

Does not work good with other objects like cylinders etc..?? //x

The parameter length determines the size of the smaller objects.

Example: Cube with sides (1x1x1) and parameter length 0.1 => 10 small cubes will be fit along each side, so the cube will then contain 10*10*10=1000 small cubes.

Press ctrl+w to see the lattice model and get an impression of the refinement. Press ctrl+r to see the original model again

Parameters:

length size of the smaller objects that fill up the incident object
