alright, I have implemented the code, but nothing is displaying...
Initialization
// -- Create FBO
//Create Rendering buffer
glGenRenderbuffersEXT(1, &flamesFBODepth); // Create render buffer
glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, flamesFBODepth); // Bind the render buffer
glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT, GL_DEPTH_COMPONENT, sw, sh);
glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_RENDERBUFFER_EXT, flamesFBODepth);
//Create Texture
glGenTextures(1, &flamesFBOTexture);
glBindTexture(GL_TEXTURE_2D, flamesFBOTexture);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, sw, sh, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
//FBO
glGenFramebuffersEXT(1, &flamesFBO);
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, flamesFBO);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT, GL_TEXTURE_2D, flamesFBOTexture, 0);
glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_RENDERBUFFER_EXT, flamesFBODepth);
//Check if it was successfully created
GLenum status = glCheckFramebufferStatusEXT(GL_FRAMEBUFFER_EXT);
if (status != GL_FRAMEBUFFER_COMPLETE_EXT)
return false;
//Unbind...
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0);
glBindTexture(GL_TEXTURE_2D, 0);
glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, 0);
Before I draw stuff that I'd like to go to my FBO
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, flamesFBO);
glPushAttrib(GL_VIEWPORT_BIT | GL_ENABLE_BIT);
glClearColor (1.0f, 0.0f, 0.0f, 1.0f);
glLoadIdentity();
Then its my rendering code, then
glPopAttrib();
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0);
Afterwards, when I want to render the FBO to the screen...
glBindTexture(GL_TEXTURE_2D, flamesFBOTexture);
glBegin(GL_QUADS);
glTexCoord2f(0.0f, 0.0f);
glVertex3f(-1.0f, -1.0f, 0.0f); // Bottom Left
glTexCoord2f(0.0f, 1.0f);
glVertex3f(-1.0f, 1.0f, 0.0f); // Top Left
glTexCoord2f(1.0f, 1.0f);
glVertex3f(1.0f, 1.0f, 0.0f); // Top Right
glTexCoord2f(1.0f, 0.0f);
glVertex3f(1.0f, -1.0f, 0.0f); // Bottom Right
glEnd();
glBindTexture(GL_TEXTURE_2D, 0);
And nothing appears (hooray :|)... Any ideas as to what I'm doing wrong?
