Sokol-zig update: new framebuffer module for old-school CPU rendering

floooh · August 1, 2026, 10:37am

Minor sokol-zig update: @nurpax has contributed a bindings PR and new Zig sample for the sokol_framebuffer.h header. This basically lets you do VGA Mode13h style CPU rendering with just a few lines of zig code.

To run the new sample (on macOS, Linux or Windows):

git clone https://github.com/floooh/sokol-zig && cd sokol-zig
zig build run-framebuffer

Source code:

github.com/floooh/sokol-zig

examples/framebuffer.zig

master

//------------------------------------------------------------------------------
//  framebuffer.zig
//
//  Render into a CPU framebuffer and blit to window.
//------------------------------------------------------------------------------
const std = @import("std");

const sokol = @import("sokol");
const slog = sokol.log;
const sg = sokol.gfx;
const sapp = sokol.app;
const sglue = sokol.glue;
const sfb = sokol.framebuffer;
const print = @import("std").debug.print;

const state = struct {
    var pass_action: sg.PassAction = .{};
    var fb: sfb.Framebuffer = .{};
    var pixels: [240][320]u32 = undefined;
};

Many thanks @nurpax !
