i rebild it to :
see last post at :
http://libertybasic.nl/viewtopic.php?f=4&t=637
error :
- my polygons are not sorting
future :
- split this in modules
- OOP [ it wil not be compatible whit LB anymore ]

update :
- sorting is now right
code at :
http://libertybasic.nl/viewtopic.php?f=4&t=637
see :
[solved] opengl : rot cube
and :
openGL : avatar robot
error :
- if i move the robot in z direction
it [ partly ] disapeers somtimes

To make this work in LBB you must change open for graphics to open for window (in LBB graphics windows are buffered in memory, so they 'stick' without the use of flush, and OpenGL cannot render to a memory DC):
Code:open "Avatar : robot 1.0" for window as #m
This change isn't compatible with LB 4.04 because "when characterInput [key]" is rejected, so if you want to maintain compatibility you can do:
Code: if instr(Platform$, "LBB") then
open "Avatar : robot 1.0" for window as #m
else
open "Avatar : robot 1.0" for graphics as #m
end if

It's a good example of the speed benefit of LBB over LB.
When run on a 'widescreen' (16:9) display the aspect ratio isn't right (the minion is rather fat!) but my knowledge of OpenGL is not good enough to fix it.

Under the "[tmr]" branch you can decrease the first value in the two "call glScale" lines. You should be able to use DisplayWidth & DisplayHeight to calculate the correct ratio, if you are so inclined.
Code:call glScale 0.<change me>,0.3,0.3 |

update :
- right scale
error ? :
- the animation is a litle shaky
change the Code:
WindowWidth = DisplayWidth
WindowHeight = DisplayHeight
global winx , winy
winx = WindowWidth
winy = WindowHeight
Code:
[tmr]
scan
call glClear GL.COLOR.BUFFER.BIT or GL.DEPTH.BUFFER.BIT
call glLoadIdentity
call glTranslate .6,.3,0
call glScale 0.3*winy/winx,0.3,0.3
call glRotate angle , 0,1,0
call walk.man angle * 3 , 30
call minion
call glLoadIdentity
call glTranslate -.6,0,0
call glScale 0.3*winy/winx,0.3,0.3
call glRotate angle , 0,1,0
call robot
calldll #gdi32,"SwapBuffers" _
, MainDC as ulong _
, ret as long
angle = angle + 5
wait

update :
- scaled better
Code:
WindowWidth = DisplayWidth
WindowHeight = DisplayHeight
global winx , winy , winyx
winx = WindowWidth
winy = WindowHeight
winyx = winy / winx
Code:
[tmr]
scan
call glClear GL.COLOR.BUFFER.BIT or GL.DEPTH.BUFFER.BIT
call glLoadIdentity
call glScale winyx , 1 , 1
call glPushMatrix
call glTranslate .6,.3,0
call glScale 0.3,0.3,0.3
call glRotate angle , 0,1,0
call walk.man angle * 3 , 30
call minion
call glPopMatrix
call glPushMatrix
call glTranslate -.6,0,0
call glScale 0.3,0.3,0.3
call glRotate angle , 0,1,0
call robot
call glPopMatrix
calldll #gdi32,"SwapBuffers" _
, MainDC as ulong _
, ret as long
angle = angle + 5
wait

This shows the difference in speed between LBB and LB!
The figures crawl and stutter in LB, whereas in LBB they move quickly and smoothly.

I've not looked at the updated code, but it has improved the speed on LB and no longer stutters, although it is not showing as much on the screen (it's now just a sort of doughnut).
However, loading the code into LBB shows that it is still much quicker and smoother than LB. All credit to Richard Russell and BB4W.
