3D animation using
the graph editor
In this session our tutor showed us how to use the graph
editor. The graph editor is useful for tweaking your animations.
In order to help us learn about the graph editor we were set
a task
1. To start off with we created a ball and opened the graph
editor. Key frame one where the ball is on the ground
2. Move the ball diagonally upward on frame 5 and key frame
it
3. Go onto frame 10 and move the ball diagonally
downwards
4. On frame 15 repeat what you did with frame 5
5. On frame 20 repeat what you did with frame 10. You should
now have a bouncing ball animation
6. Now go onto animate and select ghost selected then click
onto custom frame step. In ghost options set step before current frame and set
it to 10. Also select steps after current frame and set that to 10
7. With ghosting active you’re animation should look like
this
8. Now go onto graph editor and adjust the frames, as you
can see below the bounce on my ball is noticeably uneven.
9. Now just adjust it so it looks even.
10. By pressing F it will allow you to focus on the frames
By moving the ball manually we can change the timing. Below
is an image of it before
Here is it now, if you notice it has changed
11. Go to frame 15 in the graph editor
By using the middle mouse button you can change the
direction of the tangent
12. Now right click on frame 15 and select brake tangent and
it should go blue
The line has now gone
a light blue
You can now move one tangent
13. I am now going to show you how to change their size. Go
onto curves and click on weighted tangents
14. Now go onto tangent and click on free tangent weights
You can now edit their size as well as their direction
What I learned
By doing this, I learned how to use the graph editor which
will be very handy for creating animations, in the way of manipulating movement
and scale. I plan to use what I have learned in my four animations in my 3D
animation project.
