Detailed Description

The basis class for camera models.

Camera describes the projection type of the view. Usual projection are planar, perspective and fish-eye. If you want to render an image taken with an EOS 100, you have to create a corresponding Camera.

Function Documentation

virtual void Camera::eval	(	vec2 &	uv,
		ray &	r
	)			[pure virtual, inherited]

Creates a ray from uv coordinates.

Parameters:

	uv	the parameter for ray parametrization
	r	the resulting ray

virtual void Camera::evaln	(	int	n,
		vec2 *	uvs,
		ray *	rays
	)			[pure virtual, inherited]

Creates n rays from uv coordinates.

Parameters:

	n	the number of elements
	uvs	the parameter array for ray parametrization
	rays	the resulting rays array

virtual bool Camera::initialize	(	vec3 &	position,
		vec3 &	target,
		vec3 &	vertical,
		float	iar
	)			[pure virtual, inherited]

Intilialize the Camera given the view point informations.

Parameters:

	pos	the view position
	tri	the trihedron of the view
