Detailed Description

A camera with perspective projection (composite node).

See Camera base class for further information.

Initial parameters:

• vertical field of view: 60 deg
  
• near distance: 0.01
  
• far distance: 1000.0

Constructor & Destructor Documentation

PerspectiveCamera()

scg::PerspectiveCamera::PerspectiveCamera

(

)

Constructor.

~PerspectiveCamera()

virtual scg::PerspectiveCamera::~PerspectiveCamera ( )

virtual

Destructor.

Member Function Documentation

create()

static PerspectiveCameraSP scg::PerspectiveCamera::create ( )

static

Create shared pointer.

Examples

scg3_table_scene_example.cpp.

init()

void scg::PerspectiveCamera::init	(	GLfloat	fovyDeg,
		GLfloat	near,
		GLfloat	far
	)

Initialize perspective projection. Aspect ratio is determined in updateProjection() from current viewport dimensions.

Parameters

fovyDeg	vertical field of view angle (degrees)
near	near distance
far	far distance

updateProjection()

virtual void scg::PerspectiveCamera::updateProjection ( )

virtual

Update projection matrix from current viewport dimensions, called by Renderer::render() (or derived class) if window has been resized.

Implements scg::Camera.
