Detailed Description

Render slice of 3d image.

A slab is a planar slice through a 3D map. Its orientation is defined by a plane. The value range and coloring of the slab can be adjusted with the ColorBy() methods.

Definition at line 46 of file map_slab.hh.

void ColorBy	(	const Color &	c1,
		const Color &	c2
	)

color by interpolating between two colors with min/max of slab

void ColorBy	(	const Color &	c1,
		const Color &	c2,
		float	minv,
		float	maxv
	)

color by interpolating between two colors with explicit min and max values

void ColorBy

virtual geom::AlignedCuboid GetBoundingBox

(

)

const [virtual]

returns the left-bottom-front and the right-top-back corner that encompasses all graphical elements in this object

the bounding box is in local coordinates. to obtain the coordinates in the scene, multiply the bounding box by the object's transformation matrix.

Reimplemented from GfxObj.

virtual geom::Vec3 GetCenter

[protected]

void SetPlane

(

const geom::Plane &

p

)

set slab plane

Will force an update of the slab.
