Frame Buffer Objects

OpenGL OpenGL: Basic Coding

I am attempting to use Frame Buffer Objects. I start with:

GLuint fbo;
glGenFramebuffersEXT(1, &fbo);

The variable frame is unchanged by the above code. This seems like it should be pretty straight forward. Please help.

When you say “the variable frame is unchanged” you mean that the value doesn’t change?

As you don’t initialized the variable with another value, who knows, it could be using the same value. You could try to use the frame buffer object, and if it doesn’t works, start to be concerned.

Anyway, the spec has several examples:

Sorry, the variable fbo is unchanged.
and
glIsFramebufferEXT(fbo) returns false

Do you have a context bound?
