Detailed Description

Geometric entity.

This class is used to describe geometric elements. Geometry is used by Object to draw complex objects with differents shapes and materials.

The geometry is described by its location in the local space of its parent entity, but this entity is mainly an Object instance.

The main purpose of a Geometry is to compute hits between itself and some euclidian in the global space referential.

Constructor & Destructor Documentation

Geometry() [1/3]

rt::Geometry::Geometry

(

Entity *

parent = 0

)

Main constructor.

Parameters

parent

The parent entity of the geometry. To be able to draw the geometry during the render, this parent must be an Object.

Geometry() [2/3]

rt::Geometry::Geometry	(	const vector &	pos,
		Entity *	parent = 0
	)

Make a new geometry from its position and parent.

Parameters

pos	The location of the geometry in its parent local space.
parent	The parent entity of the geometry. To be able to draw the geometry during the render, this parent must be an Object.

Geometry() [3/3]

rt::Geometry::Geometry	(	double	x,
		double	y,
		double	z,
		Entity *	parent = 0
	)

Make a new geometry from its position and parent.

Parameters

x	Position of the geometry along x-axis.
y	Position of the geometry along y-axis.
z	Position of the geometry along z-axis.
parent	The parent entity of the geometry. To be able to draw the geometry during the render, this parent must be an Object.

Member Function Documentation

hits()

virtual std::vector<rt::hit> rt::Geometry::hits ( const euclidian &  e ) const

pure virtual

Compute hits between a Geometry and an euclidian.

Parameters

e	An euclidian in the global space referential.

Returns

A list of hit. If no hit occurs, the list is empty.

Implemented in rt::Sphere, rt::Plan, and rt::Mesh.

uv()

virtual vector rt::Geometry::uv ( const element &  ) const

pure virtual

UV-map a surface element on a texture.

Returns

The surface element coordinate on a texture for the UV-mapping.

Implemented in rt::Sphere, rt::Plan, and rt::Mesh.
