class	visBase::CoinFloatVertexAttribList
class	visBase::GeomIndexedShape::ColorHandler
class	visBase::ColTabTextureChannel2RGBA
class	visBase::Coordinates
	A set of coordinates. The coordinates will be transformed by the transformation before given to Coin, and transformed back when doing a getPos. More...
class	visBase::CoordListAdapter
class	visBase::DataManager
class	visBase::DataObject
	DataObject is the base class off all objects that are used in Visualization and ought to be shared in visBase::DataManager. The DataManager owns all the objects and is thus the only one that is allowed to delete it. The destructors on the inherited classes should thus be protected. More...

class	visBase::HorizonSection
class	visBase::HorizonTileResolutionTesselator
	HorizonTileResolutionTesselator class is an independent usage for tesselating coordinates, normals and primitive set of horizon tiles. it is specifically for exporting horizon to Pdf3D in which the exported horizon has no relation with the existing displayed horizon in coordinates, normals and primitive set. thus we can export horizon into different resolution without influence current displayed horizon in the secne. note: the class doesn't do anything with texture.

	Scene manages all DataObjects and has some managing functions such as the selection management and variables that should be common for the whole scene. More...
class	visBase::SceneColTab
class	visBase::SelectionManager
	SelectionManager handles DataObject that can be selected. If an object can be selected, it has to register himself with regSelObject. At registration it has to give two objects, first of all, he gives the object that outside users will associate him with when they want to add their CB to detect his selection. More...

Detailed Description

Visualization - OpenSceneGraph-based tools.

All 3D visualization in OpendTect is OpenSceneGraph (OSG) based. As usual, the external package (i.e. OSG) is not visible to any object outside this module. This module can be seen as a layer on top of the OSG library. Compliant with the 'DIF' principle (Don't implement the future), the layer only contains those tools that are really used in OpendTect.

In the 3D visualization world you'll see that it is almost unavoidable that all objects will be managed by a centralized manager. That is DataManager.

The main classes for displaying scene objects are:

• TextureRect, for inlines, crosslines and timeslices.
• RandomTrack, for random lines.
• CubeView, for the volume viewer.
• Marker, for picks.
• HorizonSection, for Horizons.
• visBase::Well, for wells.
