are GL_TEXTURE_EXTERNAL_OES texture2D coordinates normalized or no?

Question

I understand that most textures are normalized except GL_TEXTURE_RECTANGLE.

However, I can't find information on GL_TEXTURE_EXTERNAL_OES. Are the coordinates normalized or in the range of [0, imageWidth], [0, imageHeight]?

I would also appreciate if you mention where you got the information from. I couldn't find it on khronos website.

Answer 1

They use normalized texture coordinates. You can address them with texture coordinates in the range [0.0, 1.0]. While it might have been nice to point that out in the extension spec, they probably thought it was not necessary because it's just like all other textures in OpenGL ES.
