To do this, we utilize an item known as a viewport. A viewport is a shape (usually a rectangle but can be any shape) that is drawn into paper space. Think of them as a TV screen. Inserting a viewport into paper spaces places a camera into model space.
Nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high-powered atomic bonds between particles found within a nucleus.
Originally Answered: What is the difference between nuclear fusion and fission? Nuclear fission is the process of the dividing of an atomâs nucleus into 2 (or, theoretically, more) smaller nuclei. The process can occur spontaneously or (as in nuclear reactors) when a neutron strikes the nucleus and causes an instability that results in the fission.
