I think it does render invisible walls. So with grayscale, you get transparence.

no, this version doesn't rendering invisible walls  :'(
it draw all the wall, and don't clean buffers (distance rendering was not here), so it look like there is translucent wall....


.... but, I work on the engine !
-distance rendering (some bugs still here ...)
-"wired aspect" -> if all work correctly, the user will can choose the display mode
-pass from 3000 bytes to 4000 ! 
-translucent walls (and true translucent...) 

(sorry, I can't upload the librairy rigth now  )

next step : textures !

si tu veux utiliser une appv pour stocker des spirites, il faudrait plus faire

GetCalc("appvA",40)->A
// j'ai l'adresse de l'appvar
[1111111111111111]->Pic0A
[2222222222222222]
[3333333333333333]
// on a pas besoin des autres pointeurs ( les pic0B,C) car Pic0B=(Pic0A+8) et Pic0C=(Pic0A+16)
// après on va copier les spirites dans l'appv
Copy(Pic0A,A,24)


et là, on aura une appv contenant tes spirites
après pour les utiliser, on fait :

GetCalc("appvA")->A
Pt-On(0,0,A)
Pt-On(8,0,A+8)
...

j'espère avoir été clair et surtout avoir bien compris ce que tu voulais faire

thank you. it work perfectly now ! 

we can't use with Disp EXP▶Tok ??

EDIT : sorry, I was confuse by the command list. With disp it says Disp EXP>Tok whereas with text it says Text PTR>Tok

Hey, what version of AXE do you use to compile this? I'm using 1.2.1a, and I'm getting black screens at different locations.

it's axe 1.2.1a. That strange you have black screen (can I see a screenshot please ?)
(errr.... don't forget that the plolygones are render with black shapes...)

Im not sure the calc has enough memory to constitute a z-buffer or s-buffer. The way i usually do it is to sort each polygon by average z-value if that helps.

The big problems of this methode I haven't succed to create a fast sort routine ; and because I just can't sort it by the way I render things.
That's why I was looking for something else.
(and as I have understand of s-buffer, it's not taken so memory (but maybe I'm wrong))

I succed to reapet this error 6 or 7 time on an emu. 

It's look like it's a problem with a low memory situation. (RAM=10000 octets, ROM=12000 o and compiling a 5000 o prog)

And when it start to compile and there will be this error,  press ON during the comp will throw the error. 

This really a strange bug....

Sorry when i say 6-dof i meant '6-degrees of freedom' as in you can reliably move in all directions in 3d space.

ok. Basically I can do it but I haven't implemented this yet.

I'm talking syntax and what do the functions do... I know how to USE the library, just not how to program with it.

And here we are. The new library.

There is 4 important function.
GpGet() : handle the getkey
arguments : none
return : none

-rotation y axis [<-],[->]
-rotation x axis [del], [mode]
-zoom/dezoom [F1],[F5]
-up/down [F2],[F4]
-go forward/ [up],[down]

GpBegin(FLAG) : init the declaration of vertices
arguments : FLAG
choose between
GPQUADRI : the next vertices will be traited as an rectangle (need 4*nb poly vertices)
GPTRIANGLE : " as a triangle     (need 3*nb poly vertices)
return : none

GpVertex(X,Z,Y) : define a vertex
arguments : the position of the vertex
return : none

GpEnd() : finish the declaration of vertices and draw with black shape (you will can change this in the future)
if the number of the vertices is not good compare with the FLAG, return directly without drawing anything
arguments : none
return : none

If you look at the librairy, you will see many other functions. (GpRotated, GpPerpective,GpFace)
there are useless for the moment, so please don't use them !

The librairy use L1, compilated it does 4507 octets (big I know, but I am working on) and use pic1.

must use with axe 1.2.1a, (do to the 13 characters long and #ExprOn)

here an example prog :

.TEST
prgmGPLIB
While 1
GpBegin(GPTRIANGLE)
GpVertex(0,-10,0
GpVertex(0,10,0
GpVertex(20,10,0

GpVertex(20,-10,0
GpVertex(20,10,0
GpVertex(0,-10,0

GpEnd()

DispgraphClrDraw
Repeat getkey(0)
End
GpGet()
EndIf getkey(15)
Return

(I know this is slow but it's in 6MgHz  )

for the moment, I didn't upload the last version ; but when I've done that,you download it and add at the begin of the programme

.GTEST
prgmGLIB
...
your code here
...

and you can use the function provide by the library. (describe in the readme)
(all of this make me thought that I must post the file  ; but many function is not finish)
