glGetString(GL_VERSION) returns "2.1" and glGetString(GL_SHADING_LANGUAGE_VERSION) returns "1.20" This is what Apple's app, "OpenGL Driver...

thank you so much.:D I tried your code with an image and it worked. But I need to read a video stream frame by frame, process the frames ( eliminate...

Try to find out what driver version you have and change the version to match. Try glGetString(GL_VERSION) If you want or need to stay with version...

Well, it doesn't complain anymore :) But still, nothing shows up... I have never tried using shaders before, so I have no idea, where something...

hi, its hard to give you more hints without seeing the code. if you send me a priv-msg with the code i will change it for you so you see the...

Try changing "in" to "varying" and leave the version the same.

You need to describe a bit more. What sort of map - a terrain, a sensor value map, what are its coordinate system? What exactly is you OpenGL...

That didn't solve it. :( Now I get this error instead: "version '320' is not supported" The tutorial I'm reading uses version 1.50, but that does...

Edit: It doesn't seem to want me to add pictures, so if anyone could help me out with that, that would be great.

This is not a C++ forum; this is an OpenGL forum. Your questions show that you don't understand the language very well. So please go back to learning...

Wow, there is not even a single reply for this? Anyway, to clarify the problem, I have a position sensor by which x, y, and z are provided. The 2D...

You have set your version as 1.2 before "in" was valid. Change your version to 320

When I try using glimg::Dimensions dims = ImageSet->glimg::ImageSet::GetDimensions(); after I have loaded the image into an image set and...

Was, past tense. 1) I debugged, submitted patches, or otherwise precipitated them fixing things. 2) I found out they are a strictly hobbyist...

I find it odd that you are having trouble with building ClanLib on Linux. ClanLib started off being Linux only. In its beginnings it was mostly a...

Thank you for your response! I was using glFrustum(-320,320,-(WHEIGHT/2),WHEIGHT/2,-1000,1000);, but nothing was rendering. Using the glGetError()...

The fact that you say that proves that you don't know what it is. Because they're not the same thing. To clarify, `.` is used to access members of...

So I found it through some searching, and it appears to be a postfix expression. I'm sorry to waste your time with such a basic question. I have only...

hi, the Orthographic Projection may be the probem. Because of its nature you will never get a object as close to the camera as with a Perspective...

Same on Cygwin/Windows. Shall I repost this elsewhere?

*cough* : "in debug only" Why? You're not going to catch more errors that way; it just makes the coding of the feature more difficult....

You have asked about a very basic C++ concept, something you'd learn in any Introduction to C++ book. So... get such a book and read it. You'll...

Try "OpenGL 4.0 Shading Language Cookbook" e-book

I think you missed my point. If I have a vertex buffer with If I draw this buffer with GL_LINES I will get a red line from vertices 1,2 and a...

I think it's an awesome idea, but instead of starting at a random location and going sequentially from there I'd suggest that each uniform location...
