opengl - Writing to a GL_TEXTURE_3D

Question

I have a GL_TEXTURE_3D of size 16x16x6 and I write to it in a compute shader, however I can only seem to write to the values where z=0. If I attempt to call imageStore with any coordinate where z!=0 the value doesn't appear in the texture.

What could be causing this problem?

最有可能的是，您已将 3D 纹理与设置为 false 的 layered 参数绑定。检查手册页：https ://www.opengl.org/sdk/docs/man/html/glBindImageTexture.xhtml

绑定 3D 纹理时，必须使用 layered 参数，否则只能写入一层（很可能是第 0 层）。
