使用繪制LIB代表3D對象asp.net C＃

Question

我目前正在研究3D裝箱問題，我想將其結果表示為圖像。

我將結果存儲為包裝對象列表，如下所示

public class LoadedPackage
{
     private PackingObject packingObject;
     private int xloc, yloc, zloc;
     private bool flipped = false;
}

public class PackingObject
{
     private int ID, checkerMaster, height, width, depth, number;
}

我想使用xloc，yloc，zloc和尺寸來一次繪制包裝1來構建圖像。 是否有某種圖像庫方法可以做到這一點，或者我將不得不使用openGL解決方案，對於一個簡單的圖像，這對我來說似乎有點過大了。

我正在考慮也許使用使用二維gdi lib的等距方法

Answer 1

最后，我選擇了等距方法，並向每個包中添加了一種方法，以將自身從3d坐標轉換為等距。 我希望以下代碼可以幫助處於類似困境的其他人！

等距立方體有6個點，因此我返回了6個點的數組。 實際上，我使用3個子方法來返回3個等距多邊形，以供GDI庫處理，但是為了得到這個答案，我將僅發布更通用的6點方法。
