GLUT supports two types of font rendering: stroke fonts, meaning each
character is rendered as a set of line segments; and bitmap fonts, where each
character is a bitmap generated with
bitmap. Stroke fonts have the
advantage that because they are geometry, they can be arbitrarily scale and
rendered. Bitmap fonts are less flexible since they are rendered as bitmaps
but are usually faster than stroke fonts.
Render the string in the named font, without using any display lists. Rendering a nonexistent character has no effect.
If the font is a bitmap font,
renderString automatically sets the OpenGL
unpack pixel storage modes it needs appropriately and saves and restores
the previous modes before returning. The generated call to
bitmap will adjust the current raster
position based on the width of the string.
If the font is a stroke font,
translate is used to translate
the current model view matrix to advance the width of the string.
For a bitmap font, return the width in pixels of a string. For a stroke font, return the width in units. While the width of characters in a font may vary (though fixed width fonts do not vary), the maximum height characteristics of a particular font are fixed.
(freeglut only) For a bitmap font, return the maximum height of the characters in the given font measured in pixels. For a stroke font, return the width in units.
