Projections So far, transformations were used to position objects in a scene or to move them in animations. For the representation of a three-dimensional scene on a flat computer screen a projection to the two-dimensional plane is required. Such projections can also be described in terms of geometric transformations. For the representation of a three-dimensional […]
In the previous topic, objects of the virtual world were constructed with elementary geometric shapes like boxes, spheres, cylinders and cones. These simple shapes are not sufficient to model surfaces of more complex objects. This topic introduces a variety of techniques for modelling three-dimensional objects and their surfaces. Three-Dimensional Objects and Their Surfaces Before discussing […]
