Does anyone know if it is possible to use NPOT textures on Android's OpenGL ES renderer?
回答1:
Yes, for OpenGL ES 2.0, NPOT textures are supported in the core specification with some limitations in wrap modes, and 3D textures. The limitations are lifted when using the GL_OES_texture_npot extension.
For OpenGL ES 1.x, there is no extension to support NPOT textures.

It appears that Froyo does has a NPOT implementation for OpenglES 1.1. However, so far I can not get UI to displace with proper aspectio. I think Froyo has issue with this implemenation, based on a quick review of the code. Gingerbread has updated a better design like Apple's method, but I can get Gingerbread to work yet. I am having very hard time making Android to work for HW ES 1.1 that needed NPOT work-around. Has any one out there got NPOT to work with HW Opengl 1.1 with Froyo/Gingerbread ?
