OUDF103- Deformers

Create deformer > Nonlinear = Bend, Flair, Sine, Squash, Twist and wave.

– To practice using the deformers create a polygon primitive cube. Create > polygon primitive > cube

– Extend the cube in the in the channels box and add 20 subdivitions

-Then go to create deformer > Nonlinear

When the deformer is place in the scene it is show by a line, for it to work the line has to be going though the rectangle. select the deformer an the rotate it.  the attributes for the deformer are in the right hand box.

>Bend deformer

The bend tool bend objects

>Flare

The flare Bulges a objects

Sine

Sin creates a like a wave

Squash

Twist

Wave

Critical Analysis of A Animation

Finding Nemo

PLOT

Finding nemo starts off with a farther and a mother fish living in there coral reef with there 400 or so eggs, a shark attack leaves the farther alone with only one egg left. The farther rases the egg until it is a young fish, as the egg is his only child he is very protective over him. Thats the basic idea of the story is that the farther finds it hard to let go and the child as he has been too protected for so long that he is very ambits to see the open sea. The young fish begins to resent the farther for being so protective, one day the young fish is capture by fishers and then the farther begins his journey to find his spouse.

 

The farther found it hard to let go of his child and the child wanted to discover the open sea, now it has gone to the extreme the farther ha had his son take away and the son has bee taken far away. I think the main them is is the coming of age and the stresses that all parents have to go through when there child grows up.

OUDF103 – 3d animation

Process one – 3D modelling is crating the basic shape of the model through mathematical formulas often using polygons, this make up the skeleton of the model. Generally the more polygons used the smother and more detailed a model will be but the slower the rendering time, with more modern models to over come this problem they tend to concentrate on shading to create a more detailed look. Detail is then added with lighting and other effects so that it is ready for animating.

 

Process two – Animation is creating the illusion of movement thought the use of still images, using similar techniques to are used in stop animation. To create this illusion an image will be displayed on a screen e.g. monitor or television screen then replaced with an almost identical image only this time it is slightly changed E.g. a hand will be slightly moved. This is called tweening with it having a wire frame or skeleton this enables the 3d object to move or be altered. For a smoother motion around 12 of these images (frames) are displayed at within a second.

 

Process three – 3D rendering is were a three dimensional wire frame model will be converted into a still image each of these images will be made into a frame.

 

Vertices are a set potion or coordinate which can also help with other information such as colour and vector coordinates, an edge is the line that connects the coordinates. A face is a closed set of edges, so a triangle face will have three edges and a quadrilateral face will have four edges and a polygon is a set of faces, joining up to create a surface.

 

 

OUDF103 – Graphics Used In Modern Day Computer Animation

Gif – An animated gif uses the same principles of the old stop motion method. Gif stands for (graphic information file format) often-pronounced JIF.

Gif is one of the main file formats used today along side JPEG for images used on the web. It consists of a compression devise called ‘LZW’ which is able to compress an image without the loss of quality. Unlike the JPEG the Gif has a limited range of colours with a pallet of just two hundred and fifty six, this can result in images looking very grainy, this makes the Gif format un-suitable for full colour images but good for more simple graphics such as logo’s with solid areas of colour. The compression format Lempel-Ziv-Welch (LZW) used in Gif files for lossless data compression was patented in 1985, the patents have since expired but did not stop the controversy between the patent holder Unisys and CompuServe. This resuted in the creation of the Portible Network Graphics (PNG) file format, by Compuserve. Since the creation of the PNG it is becoming widly popular as it has better compretion technologie and is not limiter to the standard 256 colours. The only dounside to the PNG is that it does not have mulitiple image support unlike the Gif so it is unable to to stream picture to create a muliti image format that is used to create animation. This is simiular to the older vertion of the Gif the 87a which did not have animation capabilites untill updated to the 89a or Gif.

 

Vector – Or other names such as geometric modelling or object-oriented graphics they are made up of block colour, which is worked out by mathematical equations. For example a vector file uses maths to work out how an image is made up, it uses something similar to x and y coordinate.

 

To work out the colour of this squre the computer would do an equation. X * Y = Colour of block. So there will be no loss of image quality if the block is enlarge because the block would still equil X*Y.  Rastor graphics are still use because vector graphics find it hard to cope with high detaied images with a wide use of colour and they often look very cartoony.

 

Raster – Rastor graphic  are made up of pixels, there are worked out using code. Unlick Vector, bitmap store its information for an object for every pixle; so say if the square above is 10 * 10 pixels there would be 100 pices if information.

 

To make up that squre using a raster format such as jpeg it would doe this: Pixel 1 = Blue and to find the blue it will have a separate code as there are many shades of blue so sky blue = B28738. Pixel 2 = Gray = G363623. So there is a lot more information to be stores.

 

Unlike Vector graphics Rastor have Quality loss, so when a image is increased in size the computor has to work out how many extra pixel to add and what colour they need to be. This is to compensate for the increase in size resulting in the image looking blocky.


OUDF103 – Brief History of Flash.

One of the programs used to created animations is Flash. Flash was a program made by an ambitios teenager who started programing on an old apple 2 computer. He started writing games at an early age and had a big hit with a game called dark castle, this payed his way through college. He started writing basic drawing programs like Intellidraw. There were ideas that it would be an investment to create a program that was able to draw on a data tablet,They created a program called smartsketch; with a rival company doing the same thing at the same time and with it failing it did not leave them a very open market. They had lot of people who said they should turn smartsketch into an animations program, with the idea of the internet coming about they thought one day it may be advanced enough to send graphics down it. At the time it had to be done by java script, which at the time was dreadfully slow.  There software was used by Microsoft to create the animation properties of MSN with the new name Future Splash. In 1996 macromedia had herd enough of future splash and decided it would be an investment to work together. The creators of future splash also had another program called future wave which later became Macromedia player 1.0 with future splash  later becoming Flash.

Overview

On the whole I am happy more with myself that I was able to complete and to finish this brief to the required standard. The whole brief was to create Digital images that were fit for a purpose and not only to create but to be able to follow a process of development and to be able to document and show this process. The first part of the brief was to really acquire the skills to be able to complete the brief such as inductions and the royal armoires visit, which allowed us to have a go with cameras and to practise with our sketch book. The second part of the Brief was for use to demonstrate our skills and to create things using a creative criterion much like what a customer would have in the actual industry. The third part of the brief was for use to shore our development so the tutors could see our thinking behind our ideas.

The Verdict

This brief has really opened my eyes and made me realise the direction in that my work needs to go, in order for me to become a more productive worker, and also to lower the stress and anxiety I put myself though trying to achieve finished pieces of work by using my weaknesses. I find that I pre Judge my work and the standard that my work is and has to be by comparing it to other peoples work, as it is my work a cannot give a balanced opinion on how good it is/isn’t. As my work is my own, to me it will probably never seem good enough or one hundred percent finished as it needs an outside opinion to really see the finished product. An example of this is I had seen quite a lot of other students previous work that had been digitally painted, and it looked really good and very professional; so I thought I want my work to be that good so I decided to try doing a digital painting. By trying to do this it did not work as I was trying achieve something though one of my weaknesses, which was drawing. As I am not a naturally talented drawer, by trying to copied that particular style just led to me becoming frustrated. I then started to do some image manipulation which I did quite happily in a short period of time, but because I found this easy and I knew how easy it was for me to come up with the image I did not feel it would be seen as artistic, creative or impressive as the other digitally painted work. I then realised that image manipulation is one of my strengths and that my straights are my greatest assists and if I use them I will eventually end up with my own style. When I am doing a piece of work I have to impress myself before I think it will impress anybody else, it is not something I do intentionally but I see myself going into a industries and I always look at my work and question whether it would be good enough for it.

If I were to do any of these units again I would try to keep the brief a little simpler and have realised that it doesn’t take a ridicules amazing piece of work to be impressive or good just as long as it’s original. I would definitely not try an create and develop an idea so much that I know is really getting nowhere, and that an idea that fits the brief and does the job is worth a lot more than soothing amazingly artistic that does not fit the brief or is not finished.
