Some helpful techniques

 Hiding and Unhiding

During the process of animating I can come across a really useful tool in Maya which is the "Hide" tool. The hide tool allows me to make objects "hide" (go invisible) and they can be unhidden at any frame. This has been useful for creating bullets since once I am done using a bullet I can hide the bullet and therefore the bullet is no longer taking up any space and nor is it being rendered. The hide feature can be used by pressing CTRL + H on an object when on the correct frame. The object can also be unhidden using SHIFT + H.

Glow

Whilst creating my animation, I was always looking for a way to add a flare to the engine to give a better impression of the ships flying rather than just floating quickly in space. I attempted to use point lights and spot lights, however this did not give me the results I wanted and I found it difficult to get the right light settings possible. For example I would find that using lights, lit up other parts of the ship or would affect the lighting on the sky box which did not look right. I came to the conclusion that the best choice was to use the glow feature. This can be found in the "special effects" section in the attribute window on a material.

Here are some examples of the results I got from using the glow special effect. As you can see the glow effect gives a "powerful" shine effect which helps reflect the flare of the engine and gives a better impression of the ships flying.

The only downside I found to using the glow effect is that I now am required to render using "Maya Software" rather than "Maya Hardware." I have found that Maya Software is slower for rendering however the results make it worth the time.

SWOT Analysis

I have developed a SWOT Analysis to demonstrate the strengths, weaknesses, threats and opportunities of the experience of creating my animation.
 
Strengths

30 Second Limit – Due to the animation only needing to be 30 seconds, I can focus on the quality of the 30 seconds rather than worrying about quantity (length).

Models Already Created – Due to the models already being created from the first assignment, I do not have to worry about creating any more star wars ships.

Experience in 2D Animation – I have experience with 2D animation in Flash and this gives me a very basic idea of how animating works.

Working from home and university – Since Maya is accessible at home and at university, this means I will often be in an environment where I can use Maya to work on the animation.

 

Weaknesses

30 Second Limit – Although this is mentioned as a strength, it is also a weakness since my story is only limited to 30 seconds. This will effect the quality of the storyline.

No Experience with 3D Animation – This is going to be my first time doing 3D Animation and therefore I will be learning at the same time.

More Models – Although I already have star wars models, I will need to create additional models for my animation. This will take up some production time.

Other concerns – Due to working on another module, I will not have as much time as I wanted to work on the animation.

Opportunities

Learning – Animating in Maya will help me in the future when in the process of creating a game. As well as making my own content using Maya, I will also be able to easily communicate with experienced Maya users due to having experience using the program. 

 

Threats

Time Constraint – I only have six weeks to create my animation. With the pressure of a deadline, this gives me less time to create additions to the animation which may have improved its quality.

Organising the animation

Today I spent some time organising my animation by creating the skybox, importing my star wars models and setting up the layers (for my skybox) as well as creating groups.

(Screenshot of my groups in the outliner)

An early problem I encountered when beginning my animation is that I kept clicking the sky box by accident quite often. This became irritating however I was able to find a solution to counter this issue. I selected my sky box (sphere) and in the layer editor, created a new layer called "Template." After doing this, the sky box would no longer select when clicked on and instead if I need to select the sky box, I can do so by using the outliner.

I also spent time creating space rocks for my animation. These will be animated by rotating slowly throughout the animation. This is to prevent the animation from being plain and will also interact with one of my ships during the animation.  I have also used bump mapping on the rock to give the rock a more realistic look since the directional light should bounce off the bump mapping of the rock.

Bouncing Ball Animation

Today I created the bouncing ball animation using the guide from the "Introducing Autodesk Maya 2015" book. I found that this guide was useful and taught me many new techniques for creating animations in Maya.

The Hierarchy

The guide advised that it is a good idea for each the ball object to create three layers named "translate", "scale" and "rotate." I found this to be useful for changing each value in the X, Y and Z axis for each attribute as it kept the attributes organised into individual layers.

Using the shortcuts Shift + W, Shift + E and Shift + R allowed me to also create new frames specifically for a certain attribute.

Graph Editor

Whilst following the guide, I was introduced into using the graph editor. I found the graph editor to be useful as it showed the timing and movements between each frame demonstrating it via curves. This allowed me to get my bouncing ball animation to be as smooth as possible.

A couple of tools I used in the graph editor is the "Linear Tangents" button and the "Flat Tangents" button. By using both these tools on the ball bouncing frames and ball landing frames, I was able to get a smoother look to the ball bouncing.

Squash and Stretch Technique

The guide also taught me about the squash and stretch technique which is also used by Pixar's introduction mentioned in an earlier blog post. This allowed to make my ball bouncing animation seem more "cartoony" and satisfying. It involved modifying the scale of the ball in the Y axis so that the scale reduced two frames after hitting the ground and then increasing the scale three frames after and then reducing it back to its original scale value. 


The Animation

(Although the animation is set to 30fps, the .GIF modified the frame rate and therefore it looks slightly different to when viewed in Maya.)

Animation Techniques

In the past week, we covered the animation techniques which are to be used in our animation assignment. In the practical we also covered the animation techniques which were used in two Disney animations. This included the WALL-E Pixar introduction and a Disney Pixel short film called "One Man Band."

Animation Techniques

During the lecture, we learned about various camera shots, angles and movement. The most notable angles I learned about which I may use in my animation are:

• High & Low Angle - These angles are great at giving the audience an idea of the size of the object. Since my animation includes two ships are remarkably different sizes, I can use these angles to give the audience an idea of the difference in sizes. This can make one ship look vulnerable compared to the other ships. 
• Birds Eye View - I may use this to show the audience the speed and size comparisons of the ship. This can also be useful for showing off the setting in the current scene.
• Rule of Third - I may use this to prevent scenes from being too "crowded." A good example of using this technique could be setting the camera to show the terrain on the bottom third of the scene whilst showing the sky and ships flying over in the top two thirds. 
• Leading the Eye Rule - I may use this to show when a ship is taking off as it leads the audiences eyes towards the ship.

Disney Animation Techniques

Here are the notes collected for the WALL-E Pixar Introduction:

1.      Still camera technique.

2.      Very smooth animation style.

3.      Interaction with the company’s logo.

4.      Gives a comedic/family friendly feeling using various gimmicks such as:

•          Squashing the I in Pixar.
•          Unscrewing the light bulb in the lamp.
•          Knocking the R in Pixar.
•          Replacing the R in Pixar with a character.

5.      The lamp jumps repeatedly getting faster. It squashes and stretches as a way of jumping.

6.      The lamp goes in one direction to give anticipation of what’s happening next. The lamp stops and slides.

7.      The lamp wiggles before jumping onto the I.

8.      The lamp gives the idea that it is looking for something.

9.      The lamp looks to the faces of the audience looking for sympathy.

10.  WALL-E enters the scene looking at the audience to give the effect to the audience that it is a friendly character.

11.  Animator uses short poses (straight and sudden movement) to give the robotic animated effect of WALL-E.

12.  WALL-E’s turning of the body to the other direction lets the audience know that he is leaving.

 Here are the notes collected for the One Man Band animation:

1.      Introduction is close up on a banner using camera panning techniques. Audience most likely does not realise the setting until the camera zooms out onto the stage.

2.      Rule of three technique.

3.      Curtains reveal new character. This can be seen as an element of surprise to the audience.

4.      Characters eye becomes camera to show the character's vision.

5.      Camera zoomed onto the coin bucket with the character about to put in the coin leads to anticipation.

6.      Using specific camera angles to portray the height of the characters.For example what is known as the "high angle" and "low angle" camera shots portrayed how small and vulnerable the short character was compared to the two musicians.

7.      Camera zooming all the way out to show the setting.

8.      Coin rolling on top of the sewer drainer leads to anticipation about wherever the coin will roll over or drop down the drain.

9.      The small character repeatedly failing to use the violin leads to anticipation about wherever this character actually knows how to play the violin.

10.  Increase in speed of the animation during the playing of the instruments increases tension. Scenes also change faster.

11.  The animation hints about entry of new character by playing a new instrument before changing the camera to show the new character. Gives an element of surprise.

12.  The new characters shape indicates he is sneaky by entering the scene suddenly.

13.  The high angle over the drain demonstrates the size of it and how unlikely the coin was to fall down the drain.

All models completed

Today I finalized my three Star Wars ships. Below are the screenshots of each model with a summary of the problems I ran into, overcoming these problems, the accuracy of my models and how I could have improved:

Z-95 Headhunter

T-65 X-Wing

Sith fighter

Z-95 Headhunter

The Z-95 Headhunter was the first model I created in Maya. Whilst I was mostly happy with this model, I had one issue which I was not able to overcome at the time which is that the main base of the model is not symmetrical. I realize now that I can overcome this issue by splitting the model in half and using the "Mirror Geometry" tool which I did with one other model.

Another issue I had which I did fix recently is that my laser cannons were all made of separate cylinders. I found that although this was an easy way of creating the laser cannon, it was not very efficient and need increase my poly-count more than it needed to. I fixed this issue by deleting my laser cannon and recreating them using one cylinder and extruding the faces. I reduced the cylinders sub divisions from 20 to 15 to also reduce the poly-count caused by the extruded faces.

I think that my Z-95 Headhunter is fairly accurate to the actual model. However a problem I had when designing the model is that there are different variations and representations on how the Z95 should look when researching for images on search engines such as Google. For example this image gives the impression that the ship has a wide base whilst this image gave the impression it was thinner. This made it difficult to create an accurate representation of how the Z-95 Headhunter should truly look.

The biggest improvement I could make to my Z-95 Headhunter is improving the textures. Whilst I did apply textures to the ship, they were simple metal textures I created using the pattern tool in Photoshop. Although I did use some colour in the textures, I did not recreate individual bits of details which are in the actual ship. This is due to my lack of skills in Photoshop.

X-Wing

The X-Wing was the second model I created in Maya. One problem which occurred when designing this model was the angles of the wings. Due to the way the wings are rotated in the actual X-Wing model, I found it difficult to get a symmetrical positioning of the wings on each side. I was not able to use the Mirror Geometry tool in this case. I did partially overcome this by using the method where I would put the scale in a negative value to flip the wing. Although this helped, some wings were still not rotated properly and it took some time messing around with the scale and rotation of the wing till I was able to accurately position the wing. This made it difficult to perfectly position the wings in precise positions and rotations.

I do believe my X-Wing is accurate however there are some issues with the positioning of the four engines and four wings which could definitely use some improvement, however I did find it difficult to position without objects going through each other. Tools such as the align tool were not helpful in this case.

The biggest improvement I could have made to my X-Wing is improving the textures. Again like I mentioned with my Z-95 Headhunter, my Photoshop skills are not great so I was not able to add too much detail to my X-Wing. I feel like bump mapping may have helped greatly in improving the accuracy of my X-Wing. Another improvement I could make is the positioning of the engines and wings, however difficulties as mentioned earlier made this harder to accomplish.

Sith Fighter

The Sith Fighter was the final model I made in Maya. Since this was my last ship made, I rarely ran into any issues since most of my mistakes and issues made were experienced in my first two models and therefore I was able to avoid these issues whilst creating this model. I do realize however that I have some issues with the accuracy of the model. Comparing to other images of the Sith fighter, the top half of the wing should be larger, however due to the shape of the ship, I was unable to fix this in time for submission. There are also some other minor shape details I could have added to the bends of the wings however due to time and efficiency in polygon count, I decided to leave these details out.

Another downside as mentioned in the previous two other models is that the textures could be improved greatly. Although I did assign a texture to almost all of the objects in the scene, the textures were not great quality and do much match the actual Sith fighter with great accuracy. With better skills in Photoshop, I may have been able to get better results.
