Detailed Description

A TerrainViewController for cylindrical terrains.

This subclass interprets the y0 field as a "longitude" inside the cylinder, and considers theta and phi as relative to the tangent plane at the (x0,y0) point.

Member Function Documentation

virtual double proland::CylinderViewController::getHeight

(

)

[virtual]

Returns the height of the camera above the z=0 surface.

Reimplemented from proland::TerrainViewController.

virtual void proland::CylinderViewController::move	(	vec3d &	oldp,
		vec3d &	p
	)			[virtual]

Moves the "look at" point so that "oldp" appears at the position of "p" on screen.

Parameters:

	oldp	a terrain point.
	p	another terrain point.

Reimplemented from proland::TerrainViewController.

virtual void proland::CylinderViewController::update

(

)

[virtual]

Sets the localToParent transform of the SceneNode associated with this TerrainViewController.

The transform is computed from the view parameters x0,y0,theta,phi and d.

Reimplemented from proland::TerrainViewController.
