# Dynamics menu set - Particles, Soft/Rigid Bodies, Fields

1. Intro to Dynamics tutorial covers the Sphere bouncing off the Plane, i.e. the Ball bouncing off of the floor object. That was the first thing we did on Friday, November 7th.
2. At 13:32 on the video it switches to the topic of Particles and how particles are so often used in creating special effects.
3. At 14:57 you apply a Vortex field to the particles you have created with the Particle Tool command. When animated, it looks like a Galaxy.
4. 16:12 Render Attributes for the particleShape1. Setting the Particle Render Type to Multistreak. Tail Fade, Tail Size and Multi Count attributes are available after you click the Current Render Type button.
5. 17:07 Make an emitter. Apply a Gravity field to the emitted particles. Set the Speed attribute of the emitter so the rocket has enough speed to lift off from the earth and go explore those far, far away galaxies.
6. 18:00 Fountain look.
7. 18:08 "Last thing we're going to look at is going to be a soft body - and what exactly is a soft body?"
8. 18:30 How does the video teacher show the components of the NURBS plane?
9. 18:41 Looking at the various CVs. What is a CV? How can CV's be relevant and become part of Maya Dynamics? NURBS Control Vertices.
10. 19:02 "Now I can make this geometry a soft body. What a soft bodies going to do it basically apply particles at every single CV and its going toconstrain the CV to the particle.
11. 20:21 Make Soft
12. 20:34 Get a plus sign in the outliner. What happens when the teacher expands the NURBS plane? What does he see that got created?
13. 20:44 "Change the particle render type just to prove that there is now a particle at every CV...". We did this in the Friday November 7th class. Particles can be rendered as Spheres or Streaks instead of as points.
14. 21:09 Changing the radius value for the spheres. Turn the radius down.
15. 21:32 "I want to only be able to grab NURBS CVs. ... Watch this neat little trick."
16. 22:02 "... particles control their associated vertices ... "

17. Using softbodies video tutorial by Zach - watch only the first 6 minutes of this and you will have reviewed the Friday, November 7th class.
18. 4:16 Make Collide.
19. 5:44 Use of Goals is the beginning of material we have not yet covered in lab or lecture. Feel free to preview it ahead of time, if you want to and can spare the time now. How can the curtains be made to sway? By setting up goals for the soft body, after making the curtain object into a soft body, sort of.
