Oct 1, 2016 at 1:57 comment added Stephane Hockenhull Technically you can draw rectangles using glClear as well but that's not what it is for. But yes, the main difference between GLES1 and 2 is that 2 requires you to provide shaders. GLES1 was either running on a truly fixed pipeline GPU or the drivers created the shaders for you according to the lights, textures, and other settings.
Oct 1, 2016 at 1:46 comment added Unheilig You're right; I guess I was reading between materials that were both GLES1 and GLES2 and got mixed up. Just a quick question, so in the GLES1 era with fixed pipeline, developers could draw only using the glDraw* functions? Thanks.
