What are the steps necessary to render my scene to a Framebuffer Object(FBO) and then render that FBO to the screen?

Question

I\'ve got a fairly complicated scene with many GL_POINTS that I need to render. The scene will be largely static, so I\'d like to render it to a Framebuffer Object and then

Answer 1

Here is alternative example which does not require textures:

// copy framebuffer
if(fboUsed)
{
    glBindFramebuffer(GL_READ_FRAMEBUFFER, fboId);
    glBindFramebuffer(GL_DRAW_FRAMEBUFFER, 0);
    glBlitFramebuffer(0, 0, TEXTURE_WIDTH, TEXTURE_HEIGHT,
                      0, 0, screenWidth, screenHeight,
                      GL_COLOR_BUFFER_BIT,
                      GL_LINEAR);
    glBindFramebuffer(GL_READ_FRAMEBUFFER, 0);
 }

Replace variables in blit with your own.

Apperently frame buffer 0 is front buffer. fboId is your frame buffer number.
