3d pico-8 code example

Example 1: pico 8 3d tutorial

var rotateZ3D = function(theta) {
    var sin_t = sin(theta);
    var cos_t = cos(theta);
    
    for (var n = 0; n < nodes.length; n++) {
        var node = nodes[n];
        var x = node[0];
        var y = node[1];
        node[0] = x * cos_t - y * sin_t;
        node[1] = y * cos_t + x * sin_t;
    }
};
