Method Summary

float	getHeight() Returns the height, in units, of the volume this orthographic camera views.
Mat4f	getProjectionMatrix() Returns the projection matrix associated with this camera's parameters.
protected Vec3f	getRayStartPoint(Vec2f point, Vec3f unprojectedPoint) Computes the start point of a ray for picking, given a point in normalized screen coordinates ((0, 0) to (1, 1)) and a 3D point which that point unprojects to.
float	getWidth() Returns the width, in units, of the volume this orthographic camera views, assuming the camera's currently-set aspect ratio.
float	getWidth(float aspectRatio) Returns the width, in units, of the volume this orthographic camera views, assuming the passed-in aspect ratio.
void	render(GLRenderAction action) Support for the built-in GLRenderAction.
void	setHeight(float height) Sets the height, in units, of the volume this orthographic camera views.

Constructor Detail

OrthographicCamera

public OrthographicCamera()

Method Detail

getProjectionMatrix

public Mat4f getProjectionMatrix()

Description copied from class: Camera

Returns the projection matrix associated with this camera's parameters.

Specified by:

getProjectionMatrix in class Camera

setHeight

public void setHeight(float height)

Sets the height, in units, of the volume this orthographic camera views. The default height is 2.0 units.

getHeight

public float getHeight()

Returns the height, in units, of the volume this orthographic camera views.

getWidth

public float getWidth(float aspectRatio)

Returns the width, in units, of the volume this orthographic camera views, assuming the passed-in aspect ratio.

getWidth

public float getWidth()

Returns the width, in units, of the volume this orthographic camera views, assuming the camera's currently-set aspect ratio.

getRayStartPoint

protected Vec3f getRayStartPoint(Vec2f point,
                                 Vec3f unprojectedPoint)

Description copied from class: Camera

Computes the start point of a ray for picking, given a point in normalized screen coordinates ((0, 0) to (1, 1)) and a 3D point which that point unprojects to.

Specified by:

getRayStartPoint in class Camera

render

public void render(GLRenderAction action)

Description copied from class: Node

Support for the built-in GLRenderAction. Note that supplying virtual methods in Node subclasses to support various actions is not required due to the framework supporting action methods, but for built-in actions it may make it simpler.

Overrides:
