Re: RPi4 Problem drawing GL_POINTS anyone?

Paddy, did you set the point size?
If I don't set it I don't see anything.

Free Pascal but it's very similar.

Code: Select all

glPointSize(3.0);
  glBegin(GL_POINTS); 
  glVertex3f(10.0,15.0,0.0);
  glEnd();
GL_POINTS, GL_LINES and GL_TRIANGLES tested and working on a Pi4.

Re: Something I'd like to see.

So it is worth RPT (not RPF) producing and licensing hardware aimed at other markets. So we might see RISC-V SoC PCBs one day? er, kidding, a little ;) Assuming you guys have free time from designing CM's, Pi5, Pi6 etc ;) How much of the BCM2711 was RPT's and how much was BCM's effort? 70/30, 50/50...

Yep, CM's is a different market. Hopefully PCIe makes it to CM's. CM's would make a good core for DIY laptops? Could it led to more options than just PiTop things. since WD never made a go of it.

You might have to wait until there are some 64bit OS's for the Pi4.

If you are on Raspbian Buster, it includes STK version 0.9.3 in the repos, presumably built to use the GL renderer.
