Javascript 增量循环

Question

我正在使用 Isomer JS 库创建 3d 网格，需要帮助找出增量循环的逻辑。这是代码笔:

Javascript:

function draw() {
    var iso = new Isomer(document.getElementById("grid"));

    var Shape = Isomer.Shape;
    var Point = Isomer.Point;
    var Path = Isomer.Path;
    var Color = Isomer.Color;
    var cube = Shape.Prism(Point.ORIGIN);
    var white = new Color(255, 255, 255, 0.4);

    makeGrid(8, 8, 0, new Color(100, 100, 100, 0.6));

    for (x = 0; x < 8; x++) {
        iso.add(Shape.Prism(new Point(x, 0, 0), 1, 1, .5), white);
    }

    // GridMaker
    function makeGrid(xSize, ySize, zHeight, gridColor) {
        for (x = 0; x < xSize + 1; x++) {
            iso.add(new Path([
            new Point(x, 0, zHeight),
            new Point(x, xSize, zHeight),
            new Point(x, 0, zHeight)
            ]), gridColor);
        }
        for (y = 0; y < ySize + 1; y++) {
            iso.add(new Path([
            new Point(0, y, zHeight),
            new Point(ySize, y, zHeight),
            new Point(0, y, zHeight)
            ]), gridColor);
        }
    }
}

此代码片段创建实心 block :

for (x = 0; x < 8; x++) {
            iso.add(Shape.Prism(new Point(x, 0, 0), 1, 1, .5), white);
        }

new Point() 值按顺序排列:x、y、z。每第 8 次迭代后，我需要 y 值增加 1，这将开始将 block 放置在新行上。这也应该发生 8 次，有效地填充网格。

function draw() {
    var iso = new Isomer(document.getElementById("grid"));

    var Shape = Isomer.Shape;
    var Point = Isomer.Point;
    var Path = Isomer.Path;
    var Color = Isomer.Color;
    var cube = Shape.Prism(Point.ORIGIN);
    var white = new Color(255, 255, 255, 0.4);

    makeGrid(8, 8, 0, new Color(100, 100, 100, 0.6));

    for (x = 0; x < 8; x++) {
      for (y = 0; y < 8; y++) {
        iso.add(Shape.Prism(new Point(x, y, 0), 1, 1, .5), white);
      }
    }

    // GridMaker
    function makeGrid(xSize, ySize, zHeight, gridColor) {
        for (x = 0; x < xSize + 1; x++) {
            iso.add(new Path([
            new Point(x, 0, zHeight),
            new Point(x, xSize, zHeight),
            new Point(x, 0, zHeight)
            ]), gridColor);
        }
        for (y = 0; y < ySize + 1; y++) {
            iso.add(new Path([
            new Point(0, y, zHeight),
            new Point(ySize, y, zHeight),
            new Point(0, y, zHeight)
            ]), gridColor);
        }
    }
}
