Detailed Description

Backend for font rendering. Loads true type fonts from a file.

Member Function Documentation

void FontRenderer::createText	(	const std::string &	text,
		const std::string &	fontName,
		Scene *	scene,
		Text *	textObj
	)

Creates a Text object with the specified string and font that is associated with fontName.

Parameters

	text	string to be drawn
	fontName	name associated with the desired font and size
	scene	provides canvas size
[out]	pointer	to creates Text object

void FontRenderer::loadFont	(	const std::string &	fontPath,
		const std::string &	fontName,
		int	pixelHeight
	)

Loads a true type font from fontPath. The font is associated with fontName. The resulting font can only be used with the specified size and should not be scaled. If different font sizes are required, this method should be called once per size. Uses the library FreeType to create bitmaps for each character in the set and packs them tightly into one GL texture by using the algorithm outlines on this website.

Parameters

fontPath	path of the true type font file, relative to the folder fonts/
fontName	name that will be associated with this font and size
pixelHeight	height of 'W' in pixels

void FontRenderer::render

(

Shader *

shader)

Test method to render a character map onscreen.
