我有一个问题...是否可以仅对一个对象禁用 GL10.GL_DEPTH_TEST？在我的示例中，有一个带有 Alphashadow 纹理的 Groundplane，我想为我的 Carmodel 禁用 DEPTH_TEST 以伪造阴影。其他对象不应该禁用 DEPTH_TEST，所以我不会通过它们看到阴影。
这是一个屏幕截图（阴影没有完美地转换为它们的对象，但我想你会得到我的问题） https://dl.dropbox.com/u/18265107/special/screenshot.png

Anything you disable depth-test for will show on top of other stuff. You can choose to do, or not do, that for anything you like. However I don't think it will fix your shadows.
To achieve what you were wanting, disabling depth-test isn't enough, and you would need to render things in the right order:
- render the ground.
- render the car.
- render the shadows, with depth-test disabled.
- render the rest of the environment.
However this assumes the ground is flat, and that shadows don't cast onto other scene objects, which will probably look wrong.
