Detailed Description

Does the bulk of the work that that the Mezzanine::LineGroup performs.

Mezzanine::LineGroup is a simple wrapper around this to perform precise low level interactions with Ogre, the rendering subsystem. This uses too much stuff from ogre to use publicly. so we need to hide it here in the Mezzanine::internal namespace.

const

How big would a circle need to be to encapsulate this.

This returns the radius the a circle would need to have to surround this line group.

Returns

This returns a real number which indicates the radius.

Definition at line 317 of file linegroup.cpp.

Ogre::SceneNode * Mezzanine::Internal::Line3D::GetNode

(

)

const

Retrieves the scene node that will be used to attach this object to the scenegraph.

Returns

Returns a pointer to this LineDatas scenenode.

Definition at line 323 of file linegroup.cpp.

Whole Mezzanine::Internal::Line3D::GetNumPoints

(

)

const

How many points are in this Line3D.

Returns

This returns the amount of points stored in this class.

Definition at line 220 of file linegroup.cpp.

const Vector3 & Mezzanine::Internal::Line3D::GetPoint

(

const Whole

Index)

const

Access a specific point by index.

Parameters

index

The index.

This really does just access the underlying vector.

Returns

This Returns the specific Vector3 requested.

Definition at line 213 of file linegroup.cpp.

Real Mezzanine::Internal::Line3D::getSquaredViewDepth

(

const Ogre::Camera *

Cam)

const

Not Used.

Parameters

Cam

Not Used

Returns

This returns a Real.

const Ogre::Quaternion Mezzanine::Internal::Line3D::getWorldOrientation ( void  ) const

protected

Gets how rotated this is currently.

Returns a quaternion with the rotation

Returns

Is a Ogre::Quaternion which stores the rotation information of this Line3D

Definition at line 328 of file linegroup.cpp.

const Ogre::Vector3 Mezzanine::Internal::Line3D::getWorldPosition ( void  ) const

protected

Get the position of this Line3d.

Returns

This returns a Ogre::Vector3 with the Position relative to the world Origin

Definition at line 333 of file linegroup.cpp.

void Mezzanine::Internal::Line3D::UpdatePoint	(	const Whole	Index,
		const Vector3 &	NewValue
	)

This changes a specific point.

This replaces a point specified by index with a new point.

Parameters

Index	The index of the point to replace.
NewValue	A point to replace the existing point with.

Definition at line 225 of file linegroup.cpp.
