Member Function Documentation

real_t PointShape::getIntersection	(	const Ray &	ray,
		SurfacePoint &	pt
	)			[virtual]

always returns an invalid intersection

Implements Intersectable.

Definition at line 25 of file PointShape.cpp.

bool PointShape::intersects	(	const Ray &	ray,
		real_t	tMax = INFINITY
	)			[virtual]

Returns:

false

Reimplemented from Intersectable.

Definition at line 29 of file PointShape.cpp.

void PointShape::init

(

)

[virtual]

Initializes this Transformable's world-space AABB, assuming a derived class has already filled in m_objSpaceAABB.

Reimplemented from Transformable.

Definition at line 18 of file PointShape.cpp.

void PointShape::preview

(

)

[virtual]

Display a crude OpenGL preview of this shape

Note:

Default implementation sets the ModelView matrix appropriately with respect to this Transformable's transformation

Reimplemented from Transformable.

Definition at line 42 of file PointShape.cpp.

bool PointShape::hasNormal

(

)

const [virtual]

Returns:

whether or not this Shape supports the concept of a geometric surface normal defined over its surface

Note:

default implementation returns true

Reimplemented from Shape.

Definition at line 52 of file PointShape.cpp.

virtual real_t PointShape::getSurfaceArea

(

)

[inline, virtual]

Returns:

the total surface area of this shape

Reimplemented from Shape.

Definition at line 48 of file PointShape.h.

void PointShape::_getUV

(

SurfacePoint &

pt

)

const [protected, virtual]

Implements Shape.

Definition at line 33 of file PointShape.cpp.

void PointShape::_getGeometricNormal

(

SurfacePoint &

pt

)

const [protected, virtual]

Implements Shape.

Definition at line 38 of file PointShape.cpp.
