Uhm, coma has the same problem. And I have a white page, when I go to the resourcesite or to the pureprojectpage.

Really strange.. Could you put your website on another web server ? Well if it is not too much

Now there is the 9th tutorial: Particle effects. Download the glwrapper-library(PureArea) and my new PBOGL library(http://mitglied.lycos.de/dani008/downloads/pbogl.zip)

Excellent Dragon.

Please keep these tutorial coming. You have no idea how much they help me. For the only things I know about OpenGL are what you've taught me.
(Yes, I'm being serious)

Keep up the excellent work.

Wow, these are very good. Would you consider making a reflection tutorial?

DarkDragon · Post by **DarkDragon** » Tue May 25, 2004 12:03 pm

Uhm I didn't made anything with reflection in OpenGL.

But here is the next Tutorial: 10. NURBS-Terrain

You don't have the gl wrapper of traumatic installed

But you can use this:

Code: Select all

Procedure glFrustum(Left.f, Right.f, Bottom.f, Top.f, Near.f, Far.f)
  Dim Frustum_Matrix.f(3, 3)
  Frustum_Matrix(0, 0) = (2.0 * Near)/(Right-Left)
  Frustum_Matrix(1, 1) = (2.0 * Near)/(Top-Bottom)
  Frustum_Matrix(2, 0) = (Right+Left)/(Right-Left)
  Frustum_Matrix(2, 1) = (Top+Bottom)/(Top-Bottom)
  Frustum_Matrix(2, 2) = -1.0 * ((Far+Near)/(Far-Near))
  Frustum_Matrix(3, 2) = -1.0 * ((2.0*Far*Near)/(Far-Near))
  Frustum_Matrix(2, 3) = -1.0
  glMultMatrixf_(@Frustum_Matrix(0, 0))
EndProcedure

Procedure gluPerspective(Fov.f, Ratio.f, Near.f, Far.f)
  L_Dummy.f
  Fov = (Fov/180)*3.14159
  DefType.f Left, Right, Top, Bottom
  L_Dummy = Tan(Fov*0.5)
  L_Dummy * Near
  Top = L_Dummy
  Bottom = -L_Dummy
  Left = Bottom * Ratio
  Right = Top * Ratio
  glFrustum(Left, Right, Bottom, Top, Near, Far)
EndProcedure

DO you follow your tutorial ?

What do you mean? I don't work on it anymore, but nicolaus does maybe. I am working on my other project, but those tutorials are a bit buggy and just help to get into opengl.
