OpenGL - (31. March 2007)

About

This part of my page is dedicated to the various OpenGL demos and tutorials I wrote over the last few years, which cover different aspects of OpenGL ranging from simple stuff (like basic render-to-texture) to more advanced things like OpenGL shaders. Some of the demos and tutorials are rather old but still contain useful information for beginners, so I still maintain them overe here at my new page.

  • OpenGL demos
    Various demos for this 3D graphics API. Ranging from very basic stuff over some exotic things (like Truform) over to more advanced demos using shaders. Many of them also include full sources
  • OpenGL tutorials
    Over the years I’ve written a lot of tutorials that mostly center around OpenGl. Some of them are very old but still contain information that can be usefull for beginners.

Hi Sascha! Thanks for your Newton Delphi Play Ground, it’s very interesting. Now I’m waiting for your tutorial, but would you answer this simple question? How to delete a dynamic object that was created at run time only? Thank you very much for your answer.

Saluton,
Ich wollte mal ein Spiel ausprobieren.
Leider bricht es beim Starten immer zusammen.
Was kann die Ursache sein?

10:21:00 – TGame->LoadSettings->Loading game settings
10:21:05 – [OpenGL] Vendor = NVIDIA Corporation
10:21:05 – [OpenGL] Renderer = GeForce Go 7300/PCI/SSE2/3DNOW!
10:21:05 – [OpenGL] Version = 2.0.1
10:21:05 – [OpenGL] Extension “GL_SGIS_generate_mipmap” supported
10:21:05 – [OpenGL] Extension “GL_ARB_texture_compression” supported

Bitte poste das nächste mal auf der richtigen Seite, also direkt bei Projekt “W”. Wenn das Spiel nicht läuft, und du aktuelle OpenGL-Treiber installiert hast, dann liegts wohl daran dass die Grafikkarte zu schwach ist, bzw. ihr einige Features fehlen. Eine GeForce 7300Go ist relativ schwach, ich denke ihr fehlen entweder ein paar wichtige OpenGL-Funktionen oder sie hat zu wenig Videospeicher. Ansonsten probier mal bitte die “Keine Shader”-Verknüpfung.
