Detailed Description

A ControlPoint that stays a fixed distance from another point.

The distance doesn't really mean anything, but the direction does.

void Track::EditAssist::RotationHandle::draw

(

)

const [virtual]

Draw the control point for the editor.

May draw additional lines to show bounds or to indicate what it relates to.

Uses OpenGL commands. It expects the modelview matrix to translate points from world space. Point and line primitives may be drawn. After calling, the current OpenGL colour could be anything.

Implements Track::EditAssist::ControlPoint.

Reimplemented in Track::EditAssist::VertexRotationHandle.

Definition at line 85 of file RotationHandle.cpp.

void Track::EditAssist::RotationHandle::set_centre

(

btVector3

new_centre

)

Set the point where the RotationHandle moves around.

Definition at line 137 of file RotationHandle.cpp.

void Track::EditAssist::RotationHandle::set_length

(

btScalar

new_length

)

Set the distance between the centre point and the control point.

This does not affect the direction.

Definition at line 132 of file RotationHandle.cpp.

void Track::EditAssist::RotationHandle::snap	(	btVector3 &	position,
		btVector3	normal
	)			const [virtual]

Snap a position to a valid location.

If the position is outside of the allowed radius, it is moved to the nearest position on the circle around the normal. If it is less than the allowed radius, it is moved along normal until it reaches the sphere.

Parameters:

	position	position to adjust.
	normal	unit vector pointing into the user's view.

Reimplemented from Track::EditAssist::Dragable.
