I've got a working implementation of 4d and 1d bezier curve font generator, however I'm not sure how to now transition into actually making text. As of right now I create my font by clicking and dragging control vertices on the screen, once I have a few curves aligned I designate it as a letter and save the font. But I'm not sure what coordinate system to use to make sure that I can scale the existing curves to any size? I'm thinking to have the letter sit in like a canonical box with -1 to 1 in both x and y, but then how do I re normalize the curves and still have the ability to plot points directly on screen? As of right now the control vertices are in viewport space of [0 to screen dimention], so when I plot a point I just take the client mouse coordinates. But if I choose to project the final letter to -1 to 1 space, I can only do so once I draw all the curves for that letter as I need the bounding box of all the curves. So what is the right way to approach this?
This is probably a bit convoluted, the point of the question is how do I transition from font editor to actual font. Do I have to unproject the curves when I open them in font editor and duplicate as working copies and only bake the final normalized letter into the font when I'm done editing it or else how would I do it at runtime?
