Still a lot to go, but got some very basic per vertex lightning to go. The state machine for materials and lights in GL ES 1.0 CL is surprisingly complex (given the use-case) and I'm cheating heavily here. But We have to start somewhere. There's also some severe underflow/overflow problem that I need to address.

Finally, combined the texture mapping, the lighting and the colour interpolation. I feel like this is a good proof-of-concept to stop and start reading the specs more seriously, as well as investigating what other people have done in this space, so I can learn from them. This is also a good time to start adding tests and documentation, testing on real hardware and cleaning up the code. I'm here for the long run :) #screenshotsaturday #opengl

Now, with textures on a regular Pi #Pico (non-W), running on top of Apache #NuttX #RTOS You could say now that Apache NuttX kinda, sorta, almost, but-not-really supports #OpenGL ES 1.0 CL (albeit in a very incomplete form). There are some bugs with the colour and lighting interpolation, so while it's computed, the contribution towards the final fragment were discarded. Also, the display is a different one, ST7735S-based, since it play nicer with NuttX.

@floe Yep, based on my previous work (https://bitbang.social/@montyontherun/112938143172176814) but now improved and following as much as possible the GL ES 1.0 CL specification. Currently, the only other software implementation I'm aware of is the Mesa3D, but theirs convert from fixed-point to float internally. (Let me be clear that I have the uttermost respect and admiration for their work - and I help there from time to time) edit: spelling

With a bit more work, extended the same computation to also handle the colour interpolation

...which won't obey glDisableClientState(GL_COLOR_ARRAY); for now :)

Between diapers and bottles, I managed to get it running on the Pi Pico W (with a ST7789-based) display.

@natofe @itsfoss it was a serious discussion on the dev list. FreeDOS has (I think) two package managers (one for 16 bit and another for 32 bit machines).
