V3DCamera()

V3DCamera::V3DCamera	(	const sf::Vector3f &	pos,
		float	zNear = 0.1f,
		float	zFar = 500.0f
	)

Parameters

Member Function Documentation

BoxInView()

virtual bool V3DCamera::BoxInView ( sf::Vector3f  p, sf::Vector3f  min, sf::Vector3f  max  )

virtual

Parameters

p	Centre Position of Box.
min	Lowest values in the box (possibly negative).
max	Highest values in the box.

Returns

True if box is in view.

LookAt()

void V3DCamera::LookAt

(

const sf::Vector3f &

pos

)

Parameters

pos	The target position for the camera to look at.

Orientation()

glm::mat4 V3DCamera::Orientation

(

)

const

Returns

Calculated the rotation matrix.

PointInView()

virtual bool V3DCamera::PointInView ( sf::Vector3f  p )

virtual

Parameters

p	Position of 3D Point.

Returns

True if

ProjectionMatrix()

virtual glm::mat4 V3DCamera::ProjectionMatrix ( ) const

pure virtual

Returns

The calculated Projection Matrix of the Camera.
