Constructor & Destructor Documentation

Track::EditAssist::VertexRotationHandle::VertexRotationHandle ( std::size_t  vertex_id,
Direction  direction = DIR_FORWARD 

Create for indicating a direction at a vertex.

vertex_id The name of the vertex to associate with.
direction The direction to indicate.

Definition at line 31 of file VertexRotationHandle.cpp.

Member Function Documentation

void Track::EditAssist::VertexRotationHandle::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.

Reimplemented from Track::EditAssist::RotationHandle.

Definition at line 116 of file VertexRotationHandle.cpp.

boost::shared_ptr< Document::DocumentDelta > Track::EditAssist::VertexRotationHandle::make_delta ( btVector3  position  )  const [virtual]

Make a DocumentDelta performing the rotation.

The rotation is picked to keep the angle as close as it can be to its current value while moving the VertexRotationHandle to the requested position.

position The desired new location of the vertex. This should have been generated by Snap().
shared pointer to a new DocumentDelta that rotates the associated vertex to the most appropriate angle.

In 180 degree case use another handle's direction?

Implements Track::EditAssist::Dragable.

Definition at line 38 of file VertexRotationHandle.cpp.

void Track::EditAssist::VertexRotationHandle::update_angle ( btQuaternion  angle  ) 

Update the angle of the vertex.

This must be called for make_delta() to work. This will automatically update the position to reflect the angle, centre, and length.

angle The new angle of the vertex.

Definition at line 106 of file VertexRotationHandle.cpp.
