Member Function Documentation

QuickRayIntersection()

override bool PGENLib.Sphere.QuickRayIntersection ( Ray  ray )

virtual

Determine whether a ray hits the shape or not

Parameters

ray

Returns

Exceptions

NotImplementedException

Reimplemented from PGENLib.Shape.

RayIntersection()

override? HitRecord PGENLib.Sphere.RayIntersection ( Ray  ray )

virtual

Compute the intersection between a ray and the shape.

Parameters

ray

Returns

Returns a HitRecord, or Null if the ray doesn't hit the sphere.

Reimplemented from PGENLib.Shape.

SphereNormal()

Normal PGENLib.Sphere.SphereNormal	(	Point	point,
		Vec	dir
	)

Computes the normal in the intersection point of a ray and the surface of a unit sphere. The normal has always the opposite direction with respect to a given Ray.

Parameters

point	Type Point
dir	Type Vec

Returns

Normal

SpherePointToUv()

Vec2d PGENLib.Sphere.SpherePointToUv

(

Point

point

)

Convert the 3D intersection point into a 2D point, of coordinates (u,v).

Parameters

point

Returns

Vec2d
