Constructor & Destructor Documentation

Menge::SceneGraph::Shape::Shape	(	float	r,
		float	g,
		float	b,
		GLenum	s = `GL_FILL`
	)

inline

Constructor with color and drawing style.

Parameters

r	The red component of the shape's color (in the range [0, 1]).
g	The green component of the shape's color (in the range [0, 1]).
b	The blue component of the shape's color (in the range [0, 1]).
s	OpenGL render style: GL_FILL, GL_LINE, or GL_POINT.

void Menge::SceneGraph::Shape::setColor ( const Vector3 & vec )

inline

Set the shape color from a vector.

Parameters

vec	The rgb color, where each channel lies in the range [0, 1].

void Menge::SceneGraph::Shape::setColor	(	float	r,
		float	g,
		float	b
	)

inline

Set the shape color from three separate values.

Parameters

r	The red component of the shape's color (in the range [0, 1]).
g	The green component of the shape's color (in the range [0, 1]).
b	The blue component of the shape's color (in the range [0, 1]).

void Menge::SceneGraph::Shape::setStyle ( GLenum style )

inline

Set the shape's render style.

Parameters

style The desired render style. Should be one of GL_FILL, GL_LINE, or GL_POINT.
