android - openGl ES 2.0 上的反射层

Question

如何在 OpenGL ES 2.0 中制作反射地板，在其中我将看到对象的反射：球体、立方体等。我看到的一切都是桌面的 OpenGL 示例。

Answer 1

Reflections are typically done with a technique called render to texture. You render your initial scene to an FBO with an attached texture, then use that texture to render the reflection image onto a quad in the final scene. I think this article with help:
