Constructor & Destructor Documentation

glttf::Tesselator::Tesselator	(	Vectorizer &	vectorizer,
		int	windingRule
	)

Create a new tesselator and tesselate.

Create a new GLU tesselator, tesselate the vectorizer's contours, deallocate all used memory, and destroy the GLU tesselator.

Parameters:

	vectorizer	the vectorizer which has the countours to be tesselated
	windingRule	the winding rule of the glyph (glyph->outline.flags)

Exceptions:

std::runtime_error

if there's not enough memory for the tesselation, a GLU tesselator can't be created or there is a tesselation error.

Draw the tesselated result.

Parameters:
