Detailed Description
Abstract base class for geometry slice plots.
Provides functionality to select a slice of geometry along axes at any mesh level in any direction. The direction is selected with view and level in integer (mesh count) level. Provides the child class with permutated coordinate indexes. The first coordinate (index vb[0]) will be used for the horizontal axis of the plot, the second coordinate (index vb[1]) for the vertical axis and the third coordinate (index vb[2]) for the level. In three dimensions all the views are possible. In two dimensions, only VIEW_XY and VIEW_YX are possible. Here there is no separate redial index, Y is used instead.

Member Function Documentation
| virtual void Graph3D::get_bbox | ( | double | bbox[4] | ) | [pure virtual] |
Get bounding box of drawable.
Returns the bounding box of the drawable in array bbox in order xmin, ymin, xmax, ymax.
Implements Graph.
Implemented in EqPotGraph, FieldGraph, MeshGraph, ParticleGraph, and SolidGraph.
| virtual void Graph3D::plot | ( | cairo_t * | cairo, | |
| const Coordmapper * | cm, | |||
| const double | range[4] | |||
| ) | [pure virtual] |
Plot drawable with cairo.
Plot the drawable using cairo and coordinate mapper cm. The visible range of plot is given in array range in order xmin, ymin, xmax, ymax.
Implements Graph.
Implemented in EqPotGraph, FieldGraph, MeshGraph, ParticleGraph, and SolidGraph.
| void Graph3D::set_view | ( | view_e | view, | |
| int | level | |||
| ) | [inline] |
Set the view of 3D drawable.
Sets view direction to view and the view level to level.
