Kinematics Forward and Inverse

Forward kinematics refers to the use of the kinematic equations of a robot to compute the position of the end-effector from specified values for the joint parameters.


Inverse kinematics is the mathematical process of recovering the movements of an object in the world from some other data, such as a film of those movements, or a film of the world as seen by a camera which is itself making those movements. This is useful in robotics and in film animation.



After Effects Planet Task

In this lesson today we animated rotating planets. Firstly we got a surface like textures off of Moodle and organised all the files into order and made sure that are files were saved in a file on google drive to not lose any information which is important so files don’t become corrupt. Secondly,  I applied an effect called cc sphere that allows me to create the texture into a 3D sphere and take the form of my first planet while also creating a rotation that rotates 360 degrees.

I then repeated this process for another planet, however, i made it smaller so it looks like it is further away from a landscape perspective so we can see the difference in space between these to planets. Thirdly I  worked on the timing and spacing also I created a repetition effect for the planets to carry on spinning even when it goes over the set timer line. To do this I cropped the time that had the rotation animation and applied the time remap effect to the animation so it will carry on for the full 30 minutes and most importantly is to type in the word LoopOut() with the brackets included as this tells the program what to do.




After effects – Bouncing ball Task

Screen Shot 2017-01-25 at 14.00.17 1.pngFor this, after effects task, I animated a bouncing ball for starters I created a composition of a circle and began to animate it to look as if it is bouncing and to do so I had to use 2 major modes being position and scale  these were needed to create the effect of the ball bouncing I had to use precision on the keyframes on both scale and positioning. Secondly,  I had to focus on the timing and Spacing as this is the essence of animation and the speed also gives a sense of what the object is and its weight of the object. furthermore, before the ball hits the floor it’s slow and then as it bounces back it speeds up. the lastly, the squash and stretch whereby deforming the circle by stretching it before the next keyframe and then squashing which we would repeat to create the effect.



After Effects- Spaceship task



Firstly I created my own spaceship with adobe photoshop and applied it onto adobe after effects to create a simple animation of it flying through space. Creating a composition is one of the first steps to adding the spaceship to then, later on, animate it to move towards the other side of the composition.


In this image, I edited it to show all the features I used to create this flying spaceship such as new file was used to keep everything to do with the animation in one folder as for solids was for everything that is stationary and doesn’t move. furthermore, the new composition is used to create both stationary and things I will animate.



I also added a picture of the stars as a background to show that it is in space by import in a jpg file and placing it as a composition separate from the space ship so I can work on each separately without messing with the other also locking this in place helps as it meant to be stationary and not to move with the spaceship.


This image shows how I edited the position and how I used the markers to organise the position and speed of how and where the spaceship will move and end up.
