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.
Judy O. Share. Oct 7, 2015. Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, mass is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active stars. This is a balanced equation for a fusion reaction:
