Function Documentation

glDrawText()

std::pair< double, double > mrpt::opengl::internal::glDrawText	(	const std::string &	text,
		std::vector< mrpt::opengl::TTriangle > &	tris,
		std::vector< mrpt::math::TPoint3Df > &	lines,
		TEXT_STYLE	style = NICE,
		double	spacing = 1.5,
		double	kerning = 0.1
	)

renders a string in GL using the current settings.

Font coordinates are +X along the line and +Y along the up direction of glyphs. The origin is at the top baseline at the left of the first character. Characters have a maximum size of 1. linefeed is interpreted as a new line and the start is offset in -Y direction by spacing . Individual characters are separated by kerning + plus their individual with.

Parameters

text	string to be rendered, unknown characters are replaced with '?'
style	rendering style
spacing	distance between individual text lines
kerning	distance between characters

Appends to {tris,lines} the entities representing a given text including a pose and scale transformation.

It calls glDrawText() and appends its results to the provided buffers.
