Download Opengl 2.0

Phynix · 2010-03-19T10:20:23

Where can I download opengl 2.0 or later? The opengl that came with vc++ was version 1.1, and for some reason i couldn't find it on the opengl website.

This may be another simple question, but it's not working again:

Once again, it's not working. I put the code:

string prnt="FPS: %2i | %2i | Room: "+map.currentRoom().getName();
if(glewIsSupported("GL_VERSION_2_0"))glewsupported=true;
if(glewsupported)prnt.append(" glew: supported");
else prnt.append(" glew: not supported");
glPrint(prnt.c_str(), FPS.count, FPS.frames);

And it fails. I am using the same tests as in my console application, except this time from a win32 application. The code above is in my render function, and thus gets called every frame after the window is created. Do I need to somehow link the window to glew?

When you say "it fails", what do you mean? Runtime error, compile error? Nothing printed? IS glPrint from NeHe, in which case did you BuildFont?

Sorry for the confusion. By 'fails,' I just meant that it said glewsupported is false. I created the window and all, just as Brother Bob advised, but it isn't returning true when i call the glewIsSupported function.

Maybe obvious... Did you upgrade your video drivers ?

You need to make sure the right GL version is there in order to use GLSL.
You need 2.0 minimum.
Check with glGetString(GL_VERSION)

float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);

Yes, I did update the most recent video drivers from nVidia, and it says that I have version 3.2.0 when I call glGetString(GL_VERSION). What I'm thinking is that like Brother Bob said, I think it's a problem with linking the context somehow; I would think it's linked since it displays an opengl scene, but it says I don't have support for it.

Since GL 3.2 is > 2.0, you have support for it.

V-man: Yes, I realize I have support for it. The question I have is why it says that I don't have support for it. I would like to know what exactly is wrong with my code, and why wgl says that I don't have support for it.

Are you saying glewIsSupported("GL_VERSION_2_0") returns false?

Maybe update GLEW.
I use GLEW but I don't use glewIsSupported. I never had problems.
