我正试图利用Gisport3D建立一个2-Side窗口。但当时我对规模有些麻烦。

                <!-- Here Here Here Here Here  -->
            <Image Source="i:\tempa\tm.png" Width="534" Height="458" />

我希望这一形象与来源形象完全相同。

既无特定价值,也无“托阿”作用。

我如何能够得到我想要的东西?

Answer 1

我的3d项知识有限,人们也许可以更好地回答这个问题,但在3d环境下,物体的大小取决于许多东西。 3d发动机在装满时就考虑到所有障碍。树立形象只是其中的一部分。

也许会试图用照相机播放节目,或增加图像翻译。
