Weekly Comments

     This must be the last weekly comments. How sad... This week we did critique and learned from each other's work.What made me happy this week is that I got most of my shots filmed for my final project! It is looking pretty good! What made me angry this week is that my hard drive isn't compatible with the macs when it comes to transferring files onto it.In the future I want to learn how to make better faces in 3d. I always have issues when it comes to this, making a face function right and not have a ton of polygons.
     Im gonna hand out two links of interest for fun! Here is an awesome music video, I love Breakbot's music. It seems like this is completely rotoscoped and watercolor, it looks amazing!

     My link of interest this week is to picking good colors, this can apply to anything you do, whether its drawing, painting, 3d rendering, or even color correcting your film! Sycra has tons of good videos like this, give them a watch!

How does an Editor Think and Feel

     Editing does not come down to knowledge. Editing is more of an instinctive action, there is no wrong time to cut, but rather fitting the emotion of your scenes when you cut.
     When it comes down to it, editing as all about the eyes, they direct attention, and line up with what is being focused on. Changes in the eyes, tell what the audience is thinking and how they feel. To make a scene feel natural leave room before characters speak, that allows the viewer to pull from their body language then from their speech. Timing is key, you want to give the audience enough time to get the emotion from the shot, instead of cutting leaving them confused, 4 seconds can really make a big difference. Instead of telling the audience how to feel, show them how to feel.
      Rhythm is n our day to day life. Cutting on the rhythm is the best way to edit as it keeps a constant beat of a movie. When you break that rhythm you can really feel it and use it to your advantage. Using abnormal cuts can make the audience feel awkward which can really be an effective method  of portraying emotion.
     Editing is something that I need a lot of practice with, it is hard to do it right because you cannot learn how to do it right, editing comes completely with instinct. Maybe after getting more time under my belt can I become better at it. After all Practice makes perfect!

Posing Characters

     Body language is huge when it comes to communication. People can easily pull lots of information from their stance.  For example a drooping pose conveys sadness, and powerlessness, while an upright pose conveys the exact opposite.
     Now the main question is what makes a good pose? Clarity, is the single most important thing within a pose. Clarity makes it instantly readable, so the viewer does not have to think when looking at the action recognising all it has to offer. Proper Physicality shows the environment's effects upon the pose, gravity and balance are what is important here. Thier balance can show whether the character is confident or not. Keep your poses dynamic, the line of action should be easy to find and guide your eyes to the focal point. Keeping poses dynamic make them visually interesting, so avoid things like symmetry. Lastly, your poses should convey your character, and fit within their personality, this is one of the main points of the controversy about Tracer's victory pose.
      Posing is so important when it comes to animation. I really like this video, because it touches all the points about posing gives examples of each point. This article would definitely be good for anyone wanting to improve the clarity of their drawings, animations, or even film shots. Posing is definitely a skill I want to improve on, and get better at because sometimes it is very hard to get a pose understandable and be interesting at the same time. If you ever want to improve on this, goto some figure drawing classes, they really help.

Science of Photorealistic Cgi

     Computer generated imagery is a pretty cool thing, its like the virtual world and real world came together.

    First off, how does math and science tie into cgi? Well, computers are just really strong calculators, so finding a way to calculate shapes let alone 3d objects with math is extremely difficult.  Coding is definitely its own type of math, giving directions to the computer on how to control lighting and color that is accurate to what is seen in life is a challenge.
   
   There are two main ways of rendering 3D, Projection Rasterization and Ray Casting. Projection rasterization works by sending rays from an object's vertices to the camera, then filling in the shape it creates. This is still used in modern gaming as it is very fast. Ray Casting works by sending rays from the camera and detecting when they intersect with an object, then goes towards the light source seeing for another intersection to detect shadows.

    What are the issues with Rasterization and Ray Casting? First off, rasterization creates limited results. One of the issues is that whatever is drawn last is always on top, so even though an object may be behind an object. This problem is overcome with depth maps, drawing based upon distance from camera. Ray Casting's issue is that every ray must be checked against every object. This makes renders take an extremely long time, but creates lifelike results.

     The difference between Direct and Indirect lighting, is that they are two different sources of light. Direct lighting is directly from a light source for example a light bulb! Indirect lighting is light that is bounced off an object onto another object, so an orange may have a blue tone to its edge when its next to a blue wall.

      Indirect Illumination's issue is that it makes even bigger calculations.  This is a challenge in Cgi as you need to create even more rays to detect if another object is bouncing light upon it. So every object you add to a scene needs to be checked against every other object in the scene.

     How does Moore's Law and Blinn's Law relate? Moore's law is that the number of transistors on integrated circuits doubles every year. This relates saying that computers become more powerful every year, this means that rendering times should become faster, and easier on a computer's hardware. Blinn's law states that as technology improves render times remain constant. This is due to the fact as the stronger a computer becomes the more we throw at it.

     Is the art of CGI different from other art forms? I say Yes and No. It is similar to other art forms in the way we try to mimic realism with it. In all art forms we try to create our art in the way we observe our surroundings. It differs from other art forms as we use a computer to do the manual labor, of the recreation. In no way am I discrediting CGI as an art form, and anyone who does is quite honestly ignorant to the thought that goes into its usage. It still is all down to the artist to decide how they are going to use CGI in what they create.
