OpenGL or Driver Troubles?

OpenGL
1

Hi,

im working on a openGL-project and have some troubles with the visualisation of my project. On my Computer everything looks fine, but on my Laptop something gets wrong. See here:

Thats the right one (on my PC):

and the bad one (on my laptop):

It´s 1:1 the same source code. And i dont know whats the problem.
Here some information about my systems:

Hope someone can help me.

Thx and regards!

I think you have given us everything except the useful information!, eg OpenGL version and profile used by your application.
Do you detect and use extensions? How, and which are reported on each platform?
What about OpenGL version? Does your app rely upon some specific minimum version?

The biggest problem is this one:

Intel(R) HD Graphics Family

…as Intel is notoriously bad with OpenGL.

3

I dont know how to check the openG-Version. I found just some unserious tools which i dont want to install. I use Windows7. Isn´t there another Method to check it?
Btw: I use the OpenTK - GameWindow.

4

I dont know how to check the openG-Version.

Here is easy way (assuming compatibility profile which most likely what you are using)


std::cout << "
" << glGetString(GL_VERSION)
          << "
" << glGetString(GL_EXTENSIONS)
          << "
" << glGetString(GL_VENDOR);
5

i never used c++. what should i (#include) to can use these methods?

glGetString(…)

thx

6

Just printf the strings returned by each glGetString call.

7

I used this code:

/*************************************************************/ 
#include "StdAfx.h"
#include <stdio.h> 
#include <windows.h> 
#include <GL\gl.h> 
/*************************************************************/ 
#pragma comment(lib, "opengl32.lib") 
/*************************************************************/ 
int main() 
{ 
    printf("OpenGL Check
"); 
    printf("
OpenGL Version: %s
", glGetString(GL_VERSION)); 
    printf("	glGetError: %x
", glGetError()); 
    printf("OpenGL Extensionen: %s
", glGetString(GL_EXTENSIONS)); 
    printf("	glGetError: %x
", glGetError()); 

    getchar(); 

    return(0); 
} 
/*************************************************************/

and got the following result:

OpenGL Check

OpenGL Version: (null)
glGetError: 502
OpenGL Extension: (null)
glGetError: 502

8

You’re supposed to initialize OpenGL and get a valid context before calling GL functions.

9

Is it that hard to show how? As more as this is no software i want to write and profit from it, just want to check my troubles.

thx

10

… show how?

Didn’t you write the OpenGL program that you’re talking about? You must already have some library, code, or whatever that you use to create and manage that OpenGL window. Indeed, you could just hack your current code to dump those strings into a file once your OpenGL window finished opening.

So, did you write that application or not?

11

In OpenTK you should be able to get this data with the function OpenTK.Graphics.OpenGL.GL.GetString.

Just call it somewhere after you initialized your gamewindow and output the results.

12

Thx a lot!

I thought OpenGL will be updated automatically by Windows-Update, but i got no one?

GL_VERSION: 3.0.0 - Build 8.15.10.2353

Looks like you’ve got a newer Intel chipset.

I thought OpenGL will be updated automatically by Windows-Update, but i got no one?

Different hardware supports different version of OpenGL. Specifically: OpenGL 4.x has tessellation, random image write support and a number of other goodies. Intel GPU’s do not have any of these capabilities, so regardless of how new the drivers are, that hardware does not have that ability, thus it cannot report GL 4.x. [As a side note, GeForce 8xxx, 9xxx, 1xx, 2xx and 3xx also cannot support GL 4.x, but their drivers are regularly updated by NVIDIA].

My usual bet is that the Intel GPU and driver combination is what is causing your issues, but … sometimes it pays to not jump the gun.

Check got GL errors (glGetError), if an error comes up, pinpoint what GL call(s) generate the error(s).

Also, check that your shaders successfully compiled and linked on the laptop.

hi,

first thanks for your answer.
I want to remember that i use OpenTK-GameWindow. In my Programm i dont get a error, dont know why, but when you install OpenTK, u will get the OpenTK-Sample Browser. In the Sample OpenGL->Picking, thats what i implemented and what cause my problem, i get always the Error “Error at Swapbuffers: InvalidEnum”

    }
}

So the Error occure in the OnRenderFrame() when SwapBuffers() is called.

As u can see the Shader is commented and not used, so i dont use it, too. Because im a beginner in OpenGL-Programming. Could it be that thats the problem?
