upload done
You can download it from the links I give you yesterday

thx!

hebdemnobad · 4-Feb-2014 19:20:34

guys let me know if you can see the text in this scene....sometimes it renders grey, sometimes white, but at least it renders:

hi !

I've tried several time and always got the same result.

did you update Scol and openspace3d to the last release ? (I put the new one online yesterday)

I updated the voyager but not os3d.

arkeon · 4-Feb-2014 19:29:59

You can update it
it will only replace files from the OS3D setup not yours.
(save only modified plugITs if you have some)

hebdemnobad · 4-Feb-2014 19:33:55

arkeon are you seeing grey or white lettering?

Yes this time I will make sure to save my code.;)

I did some tests (in 3D and in 2d graphic with a CompBitmap), i get the same result than hebdemnobad.
Maybe a hardware support not supported by the CG or the driver ?

hebdemnobad, try to change the background color of the 3d scene and/or the ambient light. Same result ?
In my tests, the rendering changes ...

arkeon · 4-Feb-2014 21:48:11

the original problem was also on compbitmaps.

and I've debugged with a simple draw on compbitmap with a background container.
I didn't saw the problem at all since I've corrected the bitmap8 palette

iri can you send me yours tests so I could try to reproduce it with this ones

iri · 4-Feb-2014 21:57:25

In fact, the "system (!)" background seems to set in a transparency mode (hardware support, driver, ...).

For code, i deleted them, i had just written them quickly.
If our friend can try too, we'll see better and reproduces easier this problem.

Yes I'll try that.

Here the code I used for the test.
Does it make the same problem you mention ?

fun getStringSize2(font, txtList, w, h)=
  if txtList == nil then [w+1 h]
  else let txtList -> [first next] in
       let _GETstringSize font first -> [nw nh] in
         getStringSize2 font next (if nw>w then nw else w) (nh+h)
  ;;

fun getStringSize(font, str)= getStringSize2 font (lineextr str) 0 0;;

fun drawBitmap(cont, font, text, wsize, tsize)=
  let wsize -> [texWidth texHeight] in
  let tsize -> [tw th] in
  let _FILLbitmap (_CRbitmap _channel texWidth texHeight) 0xffffff -> bmpRgb in
  let _FILLbitmap8 (_CRbitmap8 _channel texWidth texHeight) 0x00 -> bmp8 in
  (
    _DRAWtext bmpRgb font (texWidth / 2) (texHeight / 2) - (th / 2) TD_CENTER 0x000000 text;
    _DRAWtext8 bmp8 font (texWidth / 2) (texHeight / 2) - (th / 2) TD_CENTER 0xff text;
    
    let _CRalphaBitmap _channel bmpRgb bmp8 nil nil -> abmp in
	(
      _CRcompBitmap _channel cont nil [0 0] OBJ_ENABLE OBJ_CONTAINER_ALLEVENTS abmp 0 0 texWidth texHeight;
    
	  //bitmaps copied in alpha bitmap so we can destroy them
	  _DSbitmap bmpRgb;
	  _DSbitmap8 bmp8;
	  
	  abmp;
	);
  );;
 
 
fun main()=	
  _showconsole;
  let _CRfont _channel 12 0 0 "Lucida Console" -> font in
  let [10 10] -> [xmargin ymargin] in
  let "Arkeon and Iri help me all the time!" -> text in
  let getStringSize font text -> [tw th] in //text height
  let [(tw + (xmargin * 2)) (th + (ymargin * 2))] -> [texWidth texHeight] in
  let _CRcontainerFromObjWin _channel nil 10 10 texWidth texHeight CO_NOCAPTION 0x0000ff "" -> cont in
  (
    let drawBitmap cont font text [texWidth texHeight] [tw th] -> abmp in
	(

Here is the same scene with a blue background....the text renders as light gray:

arkeon · 12-Feb-2014 17:32:32

hmm

did the transparency change or is it always the same on restarts ?

This can be because of the texture resolution and graphic conversion loosing precision.

try this :
- create a larger and squared texture like 512x512
- set the font larger with the bold flag

sometimes the text appears white, but most of the time it is grey. i will follow your suggestions. here is my code, I think it tracks yours more or less:

typeof widget_font= ObjFont;;
typeof message=  MessageBox;;
typeof my_widget= SO3_WIDGET;; 
typeof abitmap = AlphaBitmap;;


fun deleteOb(inst, param)=
  let (V3DgetDefaultViewport (V3DgetSessionView c3dXsession)) -> viewportstr in
    V3DremoveWidgetControl viewportstr my_widget;
  
  SO3WidgetDestroy my_widget;
  _DSalphaBitmap abitmap;
  0;;
fun drawBitmap(text, wsize, tsize)=
  let wsize -> [texWidth texHeight] in
  let tsize -> [tw th] in
  let _FILLbitmap (_CRbitmap _channel texWidth texHeight) 0xffffff -> bmpRgb in
  let _FILLbitmap8 (_CRbitmap8 _channel texWidth texHeight) 0x00 -> bmp8 in
  (
    let _CRalphaBitmap _channel bmpRgb bmp8 nil nil -> abmp in
    let _GETalphaBitmaps abmp -> [rgb alpha] in
    (
      _DRAWtext rgb widget_font (texWidth / 2) (texHeight / 2) - (th / 2) TD_CENTER 0xffffff text;
      _DRAWtext8 alpha widget_font (texWidth / 2) (texHeight / 2) - (th / 2) TD_CENTER 0xff text;
      SO3BitmapWidgetBlitAlpha my_widget abmp;
      set abitmap = abmp;
    );
    
    //bitmaps copied in alpha bitmap so we can destroy them
    _DSbitmap bmpRgb;
    _DSbitmap8 bmp8;
  );
  0;;

lol ^^ this is my fault, in the example I set the text color to 0xff
so it build a 0xff0000 color only red, in grey this correspond to 85 not 255

just replace 0xff to 0xffffff

ok i will try this

hebdemnobad · 13-Feb-2014 18:41:13

yest it works!!!!
http://ifam.net/openspace/widgetworksbl … index.html

an academic/technical question....but if you are painting into a 8bit bitmap, why do you need a full color of 0xffffff?

arkeon · 13-Feb-2014 18:42:12

good question ^^ we have to ask microsoft since this use the drawtext function ^^

Yes I think I did that but the rest of the current code wasn't working and I forgot that.

hello collleagues:

something in 1.6.4 broke the multiplayer script. the os3d editor checks the code fine on start up, but if I run the scene, the voyager crashes. Arkeon I am emailing you the log. Iri let me know if you want to see it.

fwiw here are the last few lines of the log:
