Detailed Description

A class containing helper functions for rendering geometry.

void Rocket::Core::GeometryUtilities::GenerateQuad	(	Vertex *	vertices,
		int *	indices,
		const Vector2f &	origin,
		const Vector2f &	dimensions,
		const Colourb &	colour,
		int	index_offset = `0`
	)			`[static]`

Generates a quad from a position, size and colour.

Parameters:

`[out]`	vertices	An array of at least four vertices that the generated vertex data will be written into.
`[out]`	indices	An array of at least six indices that the generated index data will be written into.
`[in]`	origin	The origin of the quad to generate.
`[in]`	dimensions	The dimensions of the quad to generate.
`[in]`	colour	The colour to be assigned to each of the quad's vertices.
`[in]`	index_offset	The offset to be added to the generated indices; this should be the number of vertices already in the array.

	)			`[static]`

Generates a quad from a position, size, colour and texture coordinates.

Parameters:

`[out]`	vertices	An array of at least four vertices that the generated vertex data will be written into.
`[out]`	indices	An array of at least six indices that the generated index data will be written into.
`[in]`	origin	The origin of the quad to generate.
`[in]`	dimensions	The dimensions of the quad to generate.
`[in]`	colour	The colour to be assigned to each of the quad's vertices.
`[in]`	top_left_texcoord	The texture coordinates at the top-left of the quad.
`[in]`	bottom_right_texcoord	The texture coordinates at the bottom-right of the quad.
`[in]`	index_offset	The offset to be added to the generated indices; this should be the number of vertices already in the array.
