No mipmapping. -TexParameter is mostly implemented, supports texcoord wrap modes, and only linear for both min and mag, or nearest for both min and mag filtering. -Texture names are implemented, but bad. - -Frame buffer and render buffers are not implemented. - -Depth and stencil are implemented, but not tested. -Blending seems to work. -Colorbuffer supports RGBA_8888 and RGB_565. - -Vertex buffer objects are implemented. -Some GL_TRIANGLES and GL_TRIANGLE_STRIPS modes for glDrawArrays and glDrawElements are implemented, but vertex order is probably wrong so culling is disabled. - -Basic apps should work, and some libhwui should work, except for frame buffer operations, which will cause exit. |
