ABSTRACT
For all intents and purposes, the world we live in is three dimensional. Therefore, if we want to construct a realistic computer model of it, the model should be in three dimensions. Geometry is the foundation on which computer graphics and specifically 3D computer graphics, which is utilized in VR, is based. As we alluded to in Chapter 5, we can create a virtual world by storing the locations and properties of primitive shapes. Indeed, the production of the photorealistic images necessary for VR is fundamentally determined by the intersection of straight lines with these primitive shapes.
