Animation is motion a round us, the movement of object, animals and human in sequence. Usually, the process when motion occurs from one point to another defying gravity or to alter space with time to create a state of illusion. Animation covers a variety of motion like particles animation, character animation, object animation and so on. As an animator there are various elements and principles that are supposed to be considered like timing, anticipation, etc. believe in making a better animation involves a factor various mathematics. Here I will talk about trigonometry and how it is involved in animation. An ancient Greek astronomer and mathematician called Hipparchus. Hipparchus was the first to introduced trigonometry as part of a major…show more content…
For a proper use of this theory, “ Each object in a 3D application consists of polygons. Every polygon has a vector that is perpendicular to the plane that contains the polygon.” (Akram) A better use of this theory is always used in 3D animation software like Maya. When shading and lightening, it’s necessary if possible to calculate the angle at which light rays reaches a plane geometry and the placement of camera. In these applications every plane geometry has a normal on its face or surface. As these normals are the orientation of the in real world. Since the angle of which the light rays reaches the plane may be different from the plane to the camera in a 3D space it is necessary to consider how it will translates in 3D space. This information is not only used geometry, shaders but found in managing key frames when animating, modeling, and surface illumination. It solves more about vertices and problem geometry avoiding cranky objects. It proves more on how objects in 3D space relates to reality. A good reason why trigonometry is an important factor to consider when working 3D animation packages is that just like the how the real world works with the application of angles and triangles that occupies space, distance and time is the same way as it works in these application. It also help the better understanding of how geometry is formed, can be used to make better objects since proper calculations will give better animations. Lastly when accurate
