Member Function Documentation

render()

bool render ( )

overridevirtual

Render the view.

Implements GlView.

type()

Type type ( ) const

overridevirtual

Return view type as 2D or 3D slice.

Implements GlView.

setOrthoSliceRefPos()

void setOrthoSliceRefPos

(

double

pos

)

Updates reference position so that the given slice will be at pos (in curve coordinates).

The position will be automatically restricted so that no ortho slice leaves the curves.

Parameters

pos	new slice pos

moveOrthoSlicePos()

void moveOrthoSlicePos

(

double

dp

)

Move the reference position by a certain amount (in world coordinates).

Parameters

dp	amount to move

removeOrthoSlice()

void removeOrthoSlice

(

int

slice

)

Remove the given orthogonal slice.

Parameters

slice

slice id

setOrthoSliceOffset()

void setOrthoSliceOffset	(	int	slice,
		double	offset )

Set the slice offset in world coordinates.

Parameters

slice	slice id
offset	new slice offset

orthoSliceOffset()

double orthoSliceOffset

(

int

slice

)

Get the slice offset in world coordinates.

Parameters

slice

slice id

Returns

slice offset
