I am trying the example code found in the HP Prime help section, but I am getting an insufficient memory error. I am using 614 KB out of my 256 MB Flash.

Syntax: FILLPOLY_P([G], {coordinates...} or [Coordinates], Color, [Alpha])

Fills the polygon specified by the provided pixel coordinates using the color provided.
If Alpha (0 to 255) is provided, the polygon is drawn with trensparency.

Example: FILLPOLY_P([(20,20),(120,120),(150,20),(180,150),(50,100)], #FF, 128)

Does the calc literally have to be empty in order to use 3D functions?

I just used the example code

Ok I tried this and no longer get the error, but nothing happens at all.

They really need to fix their help so that it provides working examples. (I mean, I went on-calc, selected FILLPOLY_P and pressed the Help key and this is what I got )

It might be a typo, though.


It works now and thanks for the help!

And wow the function even supports alpha transparency...

EXPORT POLYFADE()
BEGIN
DIMGROB_P(G1,320,240);
DIMGROB_P(G2,320,240);
BLIT_P(G1,G0);
WHILE 1 DO
FOR Z FROM 0 TO 255 STEP 1 DO
BLIT_P(G2,G1);
FILLPOLY_P(G2,{{0,0},{320,0},{320,240},{0,240}}, #FF0000, Z);
FILLPOLY_P(G2,{{Z,Z},{320,0},{320-Z,240-Z},{0,240}}, #00FFFF, Z);
BLIT_P(G0,G2);
WAIT(.25);
END;
END;
END;Now we have over 9000 possibilities!

Judging by the speed (which is the same on a real calc), don't expect Super Mario 64 or Minecraft, though (although I bet that calling every polygon in a single list might be faster, considering Tim Wessman had an entire wireframe 3D graph with polygons rotating at 20 FPS. I'll have to try with a larger list)

Wow, that's looking awesome

I have Tapatalk on mobile so I can't see ratings from there.

Also I tried this with a longer list and it didn't make a speed difference. I assume that complex shapes might be pretty fast if done from a single call. I need to investigate on the Triangle command, though, after seeing that Tim Wessman's 3D thing was done in a single call and ran at 20 FPS.

I thought that the current firmware was the only one with FILLPOLY support? (the first firmware didn't have triangle/polygon commands)

For me, in the current firmware (version 2013 11 25 Rev 5447), on a real calculator it runs as fast as in the screenshot above (smoother, actually, since the GIF is capped at 30 images per second). If I use multiple FILLPOLY_P commands in one loop, however, it starts being a bit slower (not super slow, though).
