Member Function Documentation

bool rPoint::add_to_render	(	Scene *	scene,
		PrimitiveContext *	ptx
	)

overridevirtual

Adds the point to the render if it is beyond the near plane.

Apply perspective to the point.

Implements DD::Image::rPrimitive.

References DD::Image::Scene::add_clipped_render_primitive(), DD::Image::MatrixArray::matrix(), DD::Image::Matrix4::transform(), and DD::Image::VArray::w_normalize().

bool rPoint::intersect_scanline	(	float	y,
		int &	X,
		int &	R,
		VArray &	out,
		VArray &	du,
		VArray &	dv
	)		const

overridevirtual

Intersect the point with a scanline. Return whether it was successful and the left and right intersection vertices.

Implements DD::Image::rPrimitive.

References DD::Image::Box3::f().

float rPoint::trace ( Scene * scene )

overridevirtual

Not implemented yet.

Implements DD::Image::rPrimitive.

float rPoint::distance	(	float	x,
		float	y
	)		const

overridevirtual

Distance the given screen-space point is away from the object. Returns 0 or negative if inside the object.

Implements DD::Image::rPrimitive.

float rPoint::distance_squared	(	float	x,
		float	y
	)		const

overridevirtual

Square of the distance to the nearest edge the object in screen-space. Returns 0 or negative if inside the object.

Implements DD::Image::rPrimitive.

References DD::Image::Box3::d().
