Task 6 – Constraints

There are three constraining subjects that 3D artists must take into account when it comes to 3D related things, these three constraints are the polygon count, file size and the rendering time.

Polygon Count
Creating 3D models in 3D development softwares like Blender, MAYA, 3D Studio Max etc. The models that are created are basically made up of polygons and for a polygon to create a basic 3D model it joins together which then creates a polygon mesh. But polygon count is more important than you think. The polygon count is the total amount of polygons within the 3D model and during the process of modelling the object the processor in the computer calculates the position of each of the vertex and polygons as the process proceeds.

This means that the more polygons you have the heavier the toll it will have on the processor making it slower. It's much more important for games because for movies can be rendered out but then the polygons will all have been pre-rendered where if it was in a game the player can freely look where they wish in which the hardware must render the polygons depending on where the character looks.

File Size
This is also quite and important topic because most games are put on disks with a limited storage capacity which means that they will have to compress everything that the game needs into a single disk however because games are becoming more and more advanced in graphics and gameplay they companies have decided to start putting them in two disks instead of one as the game has a huge amount of information in it so it's impossible to just put it in one disk.

This is one of the reasons why game graphics are much better in computers than consoles like the Xbox and the PlayStation because through computer people can download and install all the information needed for the game where as for consoles there is the restriction of needing the right consoles for certain games. But this doesn't mean that the PC versions are free of restraints because of how large things can be due to the computers hardware having to read all of the information included which could also take a toll on your CPU.

Rendering time
The rendering time solely depends on the length and the size of the created model in question the production, the rendering times can vary from second to minutes and even days in extreme cases.
Smaller and more amateur animations and rendered images of models may only take a matter of seconds or minutes to render and save but for big professional companies like Dreamworks and Pixar who work with such complex and realistic animations that are usually about and more long, the time that it would take for them to render could be very long it won't be in a matter of minutes or days it could take months or even years, but this all depends computers processor speed, so the better the processor the faster it would take for things to render out.

Most professional companies have computers that are made just for rendering complex and realistic animations. Rendering isn't just implemented into the production of models and animations but also when viewing such things. Real time 3D  applies 3D project and objects in a 3D software which then displays it on the screen as fast as possible which all depends on the machine or the systems performance. This is a type of rendering which is referred to as "real time" because the computer then attempts to make the render without the delay time at each of the transformation.
