This was a video regarding the basics of the fundamentals of how 3D computer graphics work. The video broke down into three parts which emphasized vertex points, polygons, and lighting. It further emphasized how 3D graphics are basically made up of shapes and lighting and these two elements specifically. The video also mentions 3D Geometry, vertex points, vertices, vectors, polygons, polygonal meshes, normal, lighting, shading, and texture maps.
The first point that the video mentions is shapes. When vertex points come together to create shapes by connecting them, polygons and triangles are created. The video emphasizes how important triangles are in 3D graphics. In addition, everything in computer graphics are created by these points and vertexes especially in things such as computer games and animations as well.
As said before lighting is a huge part of 3D graphics. Lighting is important because its what makes 2D object and visuals appear to have 3D features. In addition to lighting, normals are required. Lighting normal's in 3D programs are altered depending on the object and adjust automatically thereafter. When the light is behind the object the object will appear to be dark, which changes how the object looks and appears in a 3D space.
This gave me a lot of perspective on 3D graphics that I have never thought or been exposed to before. It was crazy seeing how these small features skew our visual perception of 3D graphics. It is also really cool to see the breakdown of something that we almost take for granted in our highly modernized and technologically advanced age.
