I am currently using windows vista and I am trying to learn the opengl api. This has confused me though about how to use opengl in windows. My confusion is opengl.org said its not as bad as everyone predicted ,but it also says that it supports 1.4 but currently they are on 2.1. At the same time all tutorials posted on websites and books seem to incorporate 2.1 ideas in windows even though it does not support it. How is this? Can you use the 2.1 tutorials and documentation with windows?
