所以这是我的非常简单的光线跟踪器的视口类。

public sealed class ViewPort
{
    public readonly Rectangle3D Rectangle;

    public readonly int Width;
    public readonly int Height;

    public Bitmap Image { get; private set; }

    public ViewPort(Rectangle3D rec, int width, int height)
    {
        this.Rectangle = rec;

        this.Width = width;
        this.Height = height;

        this.Image = new Bitmap(this.Width, this.Height);
    }

    public bool TryRecord(Ray ray)
    {
        Point3D cross;
        if (this.Rectangle.Intersect(ray, out cross))
        {
            this.Image.SetPixel(cross...,ray.Light);
        }
        else
        {
            return false;
        }
    }
}

好的,现在如何将三维点映射到二维图像?非常感谢帮助。谢谢。

像往常一样,最好是看看Scratchapixel.com,它详细解释了所有这些概念。我肯定会在网上进行一些搜索,指出这个惊人的资源:
