After a frustrating day of having the Emulator render lines strangely, and then discovering that my G1 renders them exactly as I expect, I am left to wonder how to test OpenGL (using GLSurfaceView).
Is the emulator sufficient to test code for correctness? I ask because I experienced the following on the emulator, but not on the G1, all using Ortho projection. 1) Line width depending on length! I drew a series of lines, most fairly short but several with endpoints close to the edge of the fixed- point number range. The long lines were rendered as wide. The short lines were rendered as 1 pixel wide. 2) Lines exploding to fill the whole screen when not appropriate to the scale (double the scale, line goes from 1/10th screen width to filling screen (or more). 3) Lines not appearing at all if horizontal. Is the emulator a correct openGL implementation? If I see problems on the emulator, am I likely to see them on some hardware platforms? Can I use my G1 as a reference platform? Or do I need a whole slew of phones to verify that an openGl app (scientific graphics, not animated) works across all platforms? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
