Detailed Description

A class which represents a Perspective camera in the scene.

This type of camera is designed to mimic the way the human eye sees. It is the most common projection mode used for rendering a 3D scene.

Member Function Documentation

fastArcTan()

float Perspective::fastArcTan ( float  value )

staticprivate

Helper method that calculates the inverse tangent function. This is an approximate algorithm from this source .

Parameters

value

The value to calculate the arc tangent.

Returns

The principal arc tangent of a value, in the interval [-pi/2,+pi/2] radians.

generateRay()

Ray Perspective::generateRay ( float  u, float  v, float  deviationU, float  deviationV  ) const

finalvirtual

Generates a ray with the origin in the camera.

Parameters

u	u = x / width
v	v = y / height
deviationU	deviationU = [-0.5F / width, 0.5F / width]
deviationV	deviationV = [-0.5F / height, 0.5F / height]

Returns

The new generated ray.

Implements MobileRT::Camera.
