HA4 Task 6 – Constraints

What constraints are involved in working within a 3D environment - polygon count, file size and rendering 

HA4 Task 6 – Constraints

Polygon count

Polygons are used in computer graphics to compose images that are three-dimensional in appearance and are usually but not always triangular, polygons arise when an object's surface is modelled or vertices are selected and the object is rendered in a wire frame model. This is quicker to display than a shaded model and this means that the polygons are a stage in computer animation. The polygon count refers to the number of polygons being rendered per frame.

File size 

File size measures the size of a computer file. Typically it is measured in bytes with an SI prefix. The actual amount of disk space consumed by the file depends on the file system. The maximum file size a file system supports depends on the number of bits reserved to store size information and the total size of the file system. For example, with FATWA, the size of one file cannot be equal or larger than 4 GB.

Rendering time

Real-time rendering is one of the interactive areas of computer graphics, it means creating synthetic images fast enough on the computer so that the viewer can interact with a virtual environment. The most common place to find real-time rendering is in video games. The rate at which images are displayed is measured in frames per second or Hertz. The frame rate is the measurement of how quickly an imaging device produces unique consecutive images.
