GUIDED SCENE
Compositing particles
Binary Loader 3: compositing particles

Vid1:This scene was made using five times the same emitter

This tutorial will show you some uses of the bin loader emitter.
For this tutorial I will asume that you already know the basics of the binary loader. If you have never seen a a bin loader before, please take a look here
I'm going to be using the particles created at the stream tutorial:

What we plan to do for this Binary loader tutorial is a particle base formation of a shpere.

1.-Create a new project.

2.- getting the previously calculated particles
  • We need the particles from the stream tutorial, (if you don't have them, you will need to run the previous scene). To get them into the new scene add a binary loader emitter.
  • At BIN sequence browser to the particle folder of the stream tutorial and select any file from the particle sequence (circle01). Now the bianry loader will play back those particles.

    Fig1: Filling the sphere

    Now you can play the sequence from the timeline.
    Also load the sphere object for reference, we are going to need to to check the shape
3.-Cloning the binary loader and and seting the position:
  • The idea is to clone a few time the binloader and by placing and rotating the copies, we will get the sphere.

    Fig2: Bin Loaders positions

  • We are going to be moving the emitters so set the Xform particles (node) to yes to make the particles move with the emitter.
    Move the time slider close to frame 100 so you can see the particles.
  • The first binary loader is propely set, so let's go eith the second one.
    Clone the binary loader (Binary Loader01) Ctlr+D ot Edit >> clone:

    WARNING
         A cloned binary loader form a clone may not behave properly when setting it's transformation. Always clone the original emitter.
    From the top view rotate the emitter around 30 degrees or more and place it so it fits the sphere

    Fig3: 30 degrees clone

  • Repeat the previous step with rotations of 30, 60, 90 and 120, You don't need to do this precisely. Remember that opertions can be made at any RF text field.
  • Change the color of each emitter (node), to help the visualization.


    Fig4: Visual aid when colored

  • Play the simulation. If you see a gap between the particles of each emitter, you can add another binary loader or move the emitters to avoid the gap.

4.-Offsetting the binary loader.
  • We are going to offset the binary loaders so they don't start all at the same time.
  • The first emitter to be played will be the central one. The two emitters close to the central emitter will be delayed 4 frames and the others 9.
