Is opengl 4.1 backwards compatible with 3.2

However, modern GPUs and their features have diverged from this pipeline, and support of these previous versions of OpenGL are for supporting current applications. This pipeline was the basis of many versions of OpenGL and expanded in many ways, and is still available for use. The other point of a fixed-function pipeline is that the order of operations was always the same that is, you cant reorder the sequence operations occur.

That version of OpenGL implemented whats called a fixed-function pipeline, which means that all of the operations that OpenGL supported were fully-defined, and an application could only modify their operation by changing a set of input values (like colors or positions). The initial version of OpenGL was announced in July of 1994. In this modern world of OpenGL, all applications will need to provide shaders, and as such, providing some perspective on how the pipeline evolved and its phases will be illustrative. Instead, well concentrate on showing how we can implement those techniques on a modern, shader-based graphics pipeline. If youre familiar with previous versions of OpenGL, or other rasterization-based graphics pipelines that may have included fixed-function processing, we wont be covering those techniques. In fact most of this course will discuss shaders and the operations they support. In these modern versions of OpenGL (which we defined as versions starting with version 3.1), OpenGL applications are shader based. This course concentrates on the latest versions of OpenGL specifically OpenGL 4.1. While OpenGL has been around for close to 20 years, a lot of changes have occurred in that time. Generally, this is controlled by the windowing system on whatever platform you are working on. However, in order for OpenGL to be able to render, it needs a window to draw into. That means that the part of your application that draws can be platform independent. Additionally, the OpenGL API is window and operating system independent. With it, you can create interactive applications that render high-quality color images composed of 3D geometric objects and images. OpenGL is a library of function calls for doing computer graphics.
