WebHá 2 dias · I have a OpenGL progream where I want to achieve a pixelated look. To do that I've read that you can use the framebuffer to render the scene in a lower resolution then copy over the data with glBlitNamedFramebuffer to a higher resolution.

The Default Framebuffer is the Framebuffer that OpenGL is created with. It is created along with the OpenGL Context. Like Framebuffer Objects, the default framebuffer is a series of images. Unlike FBOs, one of these images usually represents what you actually see on some part of your screen. WebExample. Framebuffer is a type of buffer which stores color values, depth and stencil information of pixels in memory. When you draw something in OpenGL the output is stored in the default framebuffer and then you actually see the color values of this buffer on screen. You can also make your own framebuffer which can be used for a lot of cool … dvc with gitlab
