FTGL 2.0
11 March 2003
TODO:
FUTURE:
- select face ie italic, bold etc
- Multiple sizes
- Optimise performance and mem usage.
- Use the Freetype Cache mechanism. FTC_xxx
- Handle non western scripts.
- Multiple Masters
- String Cache or string chunks
- Provide an interface to access the point data for outlines and
polygon meshes. Part way there with new vectoriser.
- Have a look at improving the algorthm for making curves. Maybe a
distance metric might be the way to go so that rather than having
5 polylines (0.2 step) for every curve, adjust the fineness for
the length of the curve. But then you should also test the angle
of the tangents as well.
Jed's new bezier stuff.
- Guard classes - vectoriser
- Template methods
- Move the init code out of the glyph constructors into an init
function so that they can return errors.
BUGS:
- FTExtrdGlyph - Some glyph contours are 'wound' in reverse causing
the 'sides' of the extrusions to be culled. First fix only half
worked. When calculating the winding using the summed area I need
to use the outside contour only. How do I know it's an outside
contour? A workaround is to disable face culling.
- FTGLTextureFonts can't be used inside display lists. This because the
glGet call to check the current texture id can't be used in a display
list. It is only a valid call when the list is compiled and is ignore after
that.
- Advance/Kerning is screwed up for really small point sizes eg 2 point.
This is because I'm trying to use FT_Vector which is integer based.
I will probably have to make my own struct with floats.
This might be fixed in 1.41
- The texture co-ords in the Texture Font may be wrong for non
scalable fonts.
