在OpenGL ES 2.0在Android上黑色文物 [英] Black Artifacts on Android in OpenGL ES 2

问题描述

我有一个在iOS，Android的运行一个OpenGL ES 2 code碱基，并在PC上通过的PowerVR仿真库。

I have an OpenGL ES 2 code base that runs on iOS, Android, and on PC via the PowerVR emulation libraries.

当我运行在LG擎天柱摹LGE971这code，我看到我的模型黑色工件：

When I run this code on an LG Optimus G LGE971, I see black artifacts on my model:

我的第一反应是，近裁剪平面可能是问题，但由于这些文物仅出现在选择的设备，我不认为这是问题。什么导致此任何其他的想法？

My first reaction was that the near clipping plane might be the issue, but because these artifacts appear on only select devices, I do not believe that is the issue. Any other ideas on what might be causing this?

此外，这不是很好捕获在上面的图片，但文物是不是静态的 - 他们走动作为模型旋转等

Also, this isn't captured well in the above image, but the artifacts are not static -- they move around as the model rotates, etc.

推荐答案

该问题已得到修复。我用固定的问题

The issue has been fixed. I fixed the issue by using

glTexImage2D()

与空的缓冲区，当我建立了我的mipmap水平，然后用

with NULL for the buffer when I set up my mipmap levels, and then using

glTexSubImage2D()

上传纹理数据到每个级别时

when uploading the texture data into each level.
