I will most likely archive this code since it did not lead to anything that would be useful in a production environment. This is just a truetype parser/vector graphics renderer built using OpenGL and C++. Most of the code is very hacky since I was just experimenting with this concept, but I got it to a point where it could parse some TTF fonts and display the fonts using a custom shader (albeit with a lot of lag).
I based a lot of the parsing off of Sean Barrett's Truetype parser. The rendering was based off of a research paper that I found talking about how to render fonts using the bezier curve data directly. The way I stored the bezier curve data in binary was formatted like this:
| Data Type | Name |
|---|---|
| uint32 | numGlyphs |
| uint32[numGlyphs] | offsets |
| Glyph[numGlyphs] | Glyphs |
| Data Type | Name |
|---|---|
| numContours | uint16 // If numContours is 0, this glyph is empty and the next glyph starts immediately after |
| contourEnds[numContours] | uint16 |
| numPoints | uint16 |
| flags[numPoints] | uint16 |
| xCoords[numPoints] | int16 |
| yCoords[numPoints] | int16 |
Where the Main File is the overall structure of the binary data, and the Glyph Data is how each glyph structure in the Glyph array was formatted. I may update this README with more information about how this process worked in more depth in the future.
