Inheritance diagram for mudbox::Picker:

Detailed Description

Picker objects are used as part of the map extraction process, to find points on one mesh that most closely correspond to points on another. This is used for creating displacement maps, normal maps, color maps, etc.

If you need to control the algorithm by which points are picked from a vector, you can override this class in a plug-in, and replace Mudbox's version, which is in the plugin called "BTreePicker". To create your own:

1. Write a plug-in that defines your own class derived from Picker.

2. Delete the existing BTreePicker plugin, and copy yours into the plug-in folder.

On OSX, this plugin is found in the Mudbox 2010 package, under Contents>MacOS>plugins. On the PC, it is found in the work dir folder, under "plugins"

virtual const mudbox::ClassDesc* mudbox::Picker::RuntimeClass ( void ) const [inline, virtual]

Reimplemented from mudbox::TreeNode.

    virtual void SetMesh(

const mudbox::ClassDesc* mudbox::Picker::StaticClass ( void ) [static]

Reimplemented from mudbox::TreeNode.

mudbox::Node* mudbox::Picker::CreateInstances ( unsigned int iCount = 1 ) [static]

Reimplemented from mudbox::TreeNode.

virtual void mudbox::Picker::SetMesh ( Mesh * m_pMesh ) [virtual]

Parameters:

m_pMesh

[in] Specify the mesh from which SurfacePoints can be picked

virtual bool mudbox::Picker::Pick	(	const Vector &	vLocalStart,
		const Vector &	vLocalEnd,
		bool	bBothSides,
		SurfacePoint &	cResult,
		float	fTarget = `0.5f`
	)	`[virtual]`

Parameters:

vLocalStart	[in] Start point of the picking vector, in object space
vLocalEnd	[in] End point of the picking vector, in object space
bBothSides	[in] If true, allow the mesh to be picked from either side (front or back of faces)
cResult	[out] The calculated SurfacePoint
fTarget	[in] This value, ranging from 0 to 1, represents a position on the line between vLocalStart and vLocalEnd. If there are multiple selection points, the one closes to this value is returned.
