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 !  ;D
-translucent walls (and true translucent...)  ;D

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

next step : textures !

It still doesn't draw lines whose endpoints are offscreen. Are you planning on changing that or should I stop pestering you about it? :P

That's a little bit my fault really... Axe needs proper line clipping still, it's just a pain to get right and optimized.

yes, I planing to change that ; but I need first to optimize the engine itself (and after I will see for this)
However, it's true that doing a very optimized clipping line routine is a little hard...

Looks pretty cool. How fast is it when rendering an entire room of, let's say... 10 walls (including exit)?

Yeah, it's looking pretty cool!
And that is 42 frames per second, right? ;)

According to the screenie, I would say more like 4.2 or 5 :P

it's the FOV use to render.

no, for the frame, it's more 10fps (the screenshot is more slow than the real calc  :P)

BIG UPDATE    :w00t:

-new command
-syntax command have change
-full support for 3,4 greyscale lvl and blck and white
-some very basic lightning stuff
-sorry no texture  :-\

List of command
-special command :
must be the first thing after the axe header, and they all must be here
-0/1->°LightOn    toggle on/off the lightning engine (save weight if you don't need it)

-0/1->°GBW
-0/1->°G3GreyLVL
-0/1->°G4GreyLVL     one of these three command must be on, and only one : choose the mode of display

-commands :
-GInit(FLAG)
init the declaration of vertex
FLAG is °GTRIANGLE or °GQUADRI

-GVertex(X,Z,Y)
define a vertex
draw when there is 3,or 4 vertices defines, depend on the FLAG option

-THE GEND() FUNCTION HAS BEEN REMOVE

-GRestoreID(NB_OF_FACE)
restore the list use for GDrawArray

-GSortID(ADD,NB_OF_FACE)
sort the faces  depending of the distance from the point in ADD and the pos of camera
ADD have the following format :
Data(X,Z,Y,X2,Z2,Y2 ...

-GDrawArray(ADD,NB_OF_FACE)
draw an array of vertex who have the following format :
Data(Norm,COLOR
Data(X,Z,Y
....
The number of vertex depend of the FLAG use to init
you can skip the second parameter if you have used GSortID() just before
color is all the following FLAG+ the flag °GLAMBERT, if you want to use light


FLAG->GColor
set the current face color

FLAG is :
in B&W mode
°GWHITE
°GBLACK

in 3GreyScale LVL
°GWHITE
°GGREY
°GBLACK

in 4 greyscales LVL
°GWHITE
°GGREY30
°GGREY60
°GBLACK

in all mode :
°GTWHITE   (wired aspect)

to use a light:
before the main loop put :
-1->{°GLIGHT}^r
in or before :
X->{°GLIGHT+3}
where x is the norm of the light

after, before the vertices def., you place GCalcLight(NORM_OF_FACE)->GColor at the place of FLAG->GColor
or use °GLAMBERT Flag if you use GDrawArray()

-GGetkey()
handle all the getkey


next step :
-Light at the same time than a Color definition (add the two)
-Texture

and two screenshot, B&W mode; 3 GreyLVL Mode, the  lib (ver 0.1) and the example prog  (note that I temporaly remove the Splash screen)

Why isn't it simply 2/3/4->°Grays ? That would prevent one from making a mistake and be easier to read. ;)
Other than that, this thingy looks very nice. Keep up the good work. :thumbsup:
Good luck with textures. You'll probably have a hard time with them, as you'll have to work on a sprite deformation routine and this might affect performance greatly.
