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.

Member Function Documentation

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

(

const Gradient &

g

)

color by gradient, using min/max of slab

void ColorBy	(	const Gradient &	g,
		float	minv,
		float	maxv
	)

color by gradient, using explicit min/max values

virtual void CustomPreRenderGL

(

bool

flag

)

[protected, virtual]

Reimplemented from GfxObj.

virtual void CustomRenderGL

(

RenderPass

pass

)

[virtual]

Reimplemented from GfxObj.

virtual void CustomRenderPov

(

PovState &

pov

)

[virtual]

get plane of slab

Reimplemented from GfxObj.

virtual geom::AlignedCuboid GetBoundingBox

(

bool

use_tf = true

)

const [virtual]

returns the bounding box of this object

The bounding box, i.e. the left-bottom-front and the right-top-back corner of the object, is obtained with this method. The single boolean parameter denotes whether to return local coordinates or global scene coordinates; global scene coordinates are local coordinates with the object's transformation (if present) applied. The default is false, i.e. return local coordinates.

Reimplemented from GfxObj.

virtual geom::Vec3 GetCenter

(

)

const [virtual]

get geometric center

Reimplemented from GfxObj.

geom::Plane GetPlane

(

)

const

void Rebuild

(

)

[protected]

void SetPlane

(

const geom::Plane &

p

)

set slab plane

Will force an update of the slab.
