3D 外观 2D 绘图的适当转换 (Java) [英] Appropriate Transformation for 3D-looking 2D drawing (Java)

问题描述

我正在寻找适当的转换，使 2D 图像看起来像 3D 绘图.如果我在一张纸上用平行线画一条道路"，然后将页面顶部向远离你的方向倾斜，让道路看起来消失在远处，这就是我要找的.

我正在使用 Java 并且想要一个合适的 API/库.我不相信AffineTransformation"能做到这一点.

解决方案

您不想要 AffineTransformation，因为它会始终保留平行线，这不是您在这里想要的.

幸运的是，Java Advanced Imaging API (javax.media.jai) 正是您想要的，其形式为 PerspectiveTransform 类(单击该链接获取文档).

I'm looking for the appropriate transformation to make a 2D image look like a 3D drawing. If I draw a "road" with parallel lines on a sheet of paper, and then tilt the top of the page away from you, so that the road appears to be disappearing into the distance is what I am looking for.

I'm using Java and would like an appropriate API/library. I don't believe "AffineTransformation" accomplishes this.

解决方案

You don't want an AffineTransformation, as that will always preserve parallel lines, which isn't what you want here.

Luckily the Java Advanced Imaging API (javax.media.jai) has exactly what you want, in the shape of the PerspectiveTransform class (click that link for docs).
