    • Project mention: Writing a TrueType font renderer | news.ycombinator.com | 2024-01-01

    I have a small TTF implementation that's in the neighborhood of that size and is open source. It's part of my canvas_ity single-header library [0] that's around 2300 LOC / 36 KB object size and implements a C++ version of most of the 2D HTML5 canvas spec [1].

    The core implementation of the TTF parsing and drawing is in L1526-L1846 with another small bit at L3205-L3274 of src/canvas_ity.hpp.

    It's something of a toy implementation that only supports western left-to-right text, and doesn't do any hinting at all, nor kerning, nor shaping. But it's enough to draw a basic "Hello world!" using any typical TTF file.

    The test suite in test/test.cpp L84-304 embeds a few custom Base64-encoded TTF files. They're small and only have a few glyphs but they do exercise a number of interesting edge cases in the OpenType TTF spec [2]. Have a look at the HTML5 port of the test suite at test/test.html in different browsers to see how their canvas implementations render those fonts.

    • Project mention: 3d typography - Javascriptorium 6/6 (link in the comments) | /r/creativecoding | 2023-05-11

    C++ and OpenGL are used behind the scenes so the pipeline is optimal. I can't think of another combination to make it run faster than it is now (by the way, it runs on the desktop, on mobile devices, and on the browser, without modifying a single line of code, thanks to the chronotext-cross framework.)
