The graph screen is L6, so it should be as simple as something like this:
!If GetCalc("Pic0",768)→P
.Not enough RAM
End
Copy(L₆,P,768)
Actually that's kinda wrong, since TI-OS pics are 756 bytes. how do i recall pic 0 on the screen?
sorry i am kind of new at this..
All you have to do is to access TI-OS's Pic0 with GetCalc and copy it back to L 6 (remember it's 756 bytes this time) : GetCalc("Pic0")→A
Copy(A,L6,756)
DispGraph

Actually the graph screen is L 6, aka plotSScreen. All you have to do to save it in a var is to create for example a 768-bytes appvar (plotSScreen is 768 bytes large) and copy L 6 to it. The proper way to do this would be : :GetCalc("appvSAVEDIMG",768)→A
:Return!If A // quits if the appvar couldn't be created
:Copy(L6,A) // optimized version, copies 768 bytes from A to L6

Wow, that's quite a bunch of sorry events  Despite that, it's good to see some progress on Rogue

Ask TheMachine02 for that

I think _parseInp would make the work, but I'm not sure how to use it with a string though. It executes Basic programs from a given address.

Wa  is it plain basic ? (although I guess yeah since no one has hacked the Prime yet afaik)

It looks soooooo good  will you make an ASM lib out of XLib functions ? EDIT : 1000th post ! EDIT 2 : does my sig fit the rules like this ?

Polyhedras, not polygons  and yeah, I guess that's enough but I see a way to do more, so why not trying

I generated the vertices with a For loop and a bunch of cos/sin. As-is, it's not possible to draw anything else than convex polyhedras, but I'm working on it.

Bump,
Here you go, animated screenshot (7 FPS) !

Then you'd use something like that :.alpha = int(color / 32768)
red = int(color / 1024) % 32
green = int(color / 32) % 32
blue = color % 32l
Alpha is now the 15th bit of the color, red is the 10th to 14th bits, green is the 5th to 9th bit and blue the 0th to 4th bit. You can also build a color this way :color = (alpha % 2) * 32768 + (red % 32) * 1024 + (green % 32) * 32 + (blue % 32)Assuming % is the modulo operator.

IIRC, the HP Prime's screen uses 16-bits colors (R5G6B5 format), so you can't access colors separately unless you use bitwise operators (and, or, not) and bit shifting. I don't think HP basic permits you to do that.

Sorunome : thanks Tr1p1ea : ow ow no by 3D vectors I mean vectors with 3 coordinates that's all I explained in the first post the three functions I have so far. DJ_O : oh okay I'll take care of that

No, but it'll add new features to the axiom. One usage of the vectors-related functions is the backface culling, which is a technique to dynamically remove backfacing 3D polygons. For example, in a convex polyhedra, at most 50% of the faces are visible from any viewing angle ; backface culling will then discard at least 50% of the faces, removing at least 50% of the calculations.
