Web25 de ago. de 2016 · This article discusses how to improve OpenGL* performance by swapping Frame Buffer Objects (FBO) instead of using a single FBO and swapping surfaces. Swapping is useful when making multiple changes to a rendered image, such as switching color, depth, or stencil attachments. The recommendation is to use dedicated … WebThese attachments are literally just normal OpenGL 2D textures, and so may be accessed as such. So you could, for example, render one frame into an FBO, and then use that FBO’s colour attachment as a texture in the next frame’s rendering!

WebFramebuffer object. The frame buffer object architecture (FBO) is an extension to OpenGL for doing flexible off-screen rendering, including rendering to a texture. By capturing images that would normally be drawn to the screen, it can be used to implement a large variety of image filters, and post-processing effects.
