3D Reflection and 3DSelection

DarkDragon · Post by **DarkDragon** » Mon Sep 06, 2004 5:19 pm

Hey PBUsers:

I have new pureopengl examples for you. http://www.bradan.net/downloads/demo002.zip

There is a 3DSelection code(If you want to make an 3DEditor) and a Reflection(With stencilbuffer). Maybe I can make new tutorials after my next version of my 3DEngine for you.

Feedback please

it may be my card but are the reflections program seams super slow (how fast cube should it spin?) it moves hardly and jumps some times
i have a 9100 (hey don't laugh it can doom3 at avg 20 fps..)

Uhm, well, maybe your card doesn't support StencilBuffer really good. Have you checked a newer version of your card-driver?

@DarkDragon:
Runs fine here with WinXP / GeForceMX4 440

Especially liked the Reflections-Demo ... nice work.

Hi!

Nice example! Works well on my "Matrox Millenium G550 32MB DDR".

But I've got a question about the LoadTexture_() procedure. Why is every texture loaded with this procedure vertical turned? Is it possible to load it in the right way?

Thanks!

Regards,
Christian

Code: Select all

Procedure LoadTexture_(Filename.s, TexFilter.l) ; Returns the texture for an OpenGL application
  img = LoadImage(#PB_Any, Filename.s)
  Width.l=ImageWidth()
  Height.l=ImageHeight()
  Size.l=Width * Height
  
  Dim ImageData.b(Size*3)
  
  StartDrawing(ImageOutput())
  For Y=Height-1 To 0 Step -1
    For X=0 To Width-1
     
      Color = Point(X,Y)
      ImageData(i)=Red(Color)
      i+1
      ImageData(i)=Green(Color)
      i+1
      ImageData(i)=Blue(Color)
      i+1
    
    Next
  Next
  StopDrawing()
  
  glGenTextures_(1, @Tex) ;Textur speichern
  If TexFilter = 0 ;versch. Textur-Filter
    glBindTexture_($0DE1, Tex)
    glTexParameteri_($0DE1, $2800, $2600)
    glTexParameteri_($0DE1, $2801, $2600)
    glTexImage2D_($0DE1, 0, 6407, Width, Height, 0, 6407, $1401, @ImageData()) 
  ElseIf TexFilter = 1
    glBindTexture_($0DE1, Tex)
    glTexParameteri_($0DE1, $2800, $2601)
    glTexParameteri_($0DE1, $2801, $2601)
    glTexImage2D_($0DE1, 0, 6407, Width, Height, 0, 6407, $1401, @ImageData())
  ElseIf TexFilter = 2
    glBindTexture_($0DE1, Tex)
    glTexParameteri_($0DE1, $2800, $2601)
    glTexParameteri_($0DE1, $2801, $2701)
    gluBuild2DMipmaps_($0DE1, 3, Width, Height, 6407, $1401, @ImageData())
  EndIf
  FreeImage(img)
  ProcedureReturn Tex
EndProcedure

Then it should be right.

[EDIT] Sorry posted the old code.

@Dreglor:
I have no idea, why it doesn't work well at your computer.
