Maths Week 2 Research Task

So, for todays & last Thursdays lesson we've had to research different types of numbers such as Natural Numbers, Square Numbers etc., and how they are used in the Animation, Games & VFX industry. 

Natural Numbers

  • Are a part of the number system from 1 to infinity. 
  • They don't include zero or negative numbers as well as fractions & decimals. Only positive integers.
  • Examples include 1, 2, 3 ,4....
Natural Numbers can be used in Games Design to display the amount of something is in a game. For example, Natural Numbers are used in health-bars to display the game character's health. This makes it easier for the player to see.




Rational and Irrational Numbers

  • Rational Numbers are numbers that can be in the form of a fraction that is just integers. 
  • It can also be any number which is predictable and we know where that number starts and ends.  
  • However, there are types of decimals in Rational Numbers. 
5/4 = 1.25 (Terminating Decimals)       2/3 = 0.66666666.... (recurring decimals)

  • To note, a number can be irrational if it can't be written as a fraction that is just integers.
  • Irrational Numbers doesn't terminate or recur for example, 3.14159
Prime Numbers
  • Can be greater than one
  • It can't be a product of 2 smaller numbers
  • 2, 3, 5 ,7, 11, 13, 17, 19
Prime Numbers are used, heavily in Encryption & Random Number Generators. It can also be used in digital art, too.

Square Numbers
  • Product of an integer with itself example;
1 x 1 = 1,  2 X 2 = 4, 3 X 3 = 9, 
  • It used to calculating area & volume
Pi
  • Is the Ratio of a circle's circumference, to it's diameter. 3.14159.
  • It's an irrational number. 
Eulers Numbers e
  • Another type of irrational numbers

Sculpting in Blender

-

Sculpting in Blender In Blender, our teacher showed us the sculpting tab. The Sculpting Tab in Blender is used to sculpt meshes, mainly for making realistic human models or for adding details to food models like odd crevices to a doughnut. Before getting used to Blender's Sculpting Tab, we messed around with many of the sculpting tools such as the inflate, etc., And then, for a little task, we had to have two cube meshes in the viewport. Then, I renamed both meshes, one naming "cube_low" and the other "cube_high". Then I selected mesh "cube_high", added in a Sub-Surf Modifier, and added loop cuts and brought them right to the original edges of the cube mesh. The reason why this was done is because, when applying a Sub-Surf modifier to a cube, it deforms it, making it look like an odd cylinder. So, adding loop cuts and bringing them, really tight to the original edges of the cube, can bring back it's shape. Once all that's done, I applied the su

TARDIS Compositing Project

  TARDIS Compositing Project Plan/Idea I've seen several renders of people compositing their TARDIS models on shots from various models from Doctor Who, even on-set photos. I sometimes see TARDIS composite renders in other movies, such as Bladerunner 2049 .  I wanted to do something a little different by taking actual photos of Leicester City Centre, and composite my TARDIS 3d model in those photos instead. I asked my friend, Bhadir ( bhadir.jpg on Instagram), who is a photographer and he is able to help me out with this project. Unfortunately, he is studying in London but, when he's able to come to Leicester, we'll be able to take some photos of the city centre. Bhadir has advised me to consider doing a "recce" (reconnaissance), which means surveying the area to get a good idea of what the it is, how we could take the photo, etc,. from my understanding and I do agree with him. As I'm not fully clear on how a reconnaissance is done for photography, I'll

Chase Yourself Project

  Chase Yourself Project For this project, I've been asked, by my VFX teacher, to film  a short film. The project is called "Chase Yourself".  See "Chase Yourself Documents" Blog for evidence of the Tasks done. In this project, the film is about you chasing yourself. And I'd like to think of this is a way of testing our knowledge in filming, composition & editing. Task 1 - Pre-Production Documents Pre-Production is a way of planning your short film, before actually filming it. These consists of;  Treatment Plan- A way of setting out, what your short film will be like, who'll be featured in it, the basic plot, who's the targeted audience etc, Gantt Chart - A sheet to schedule each section of a project. For example you fill in with blocks when you'll be filming etc., Location Scouting - Is essential when filming. You must find & research an area suitable for your film & write the pros & cons of said location & do a risk assessme
