Tutorial: water stream with Thinkbox Frost


 Hammer Chen

In this tutorial, you will learn how to use very simple particle setup and Thinkbox Frost, to create realtime water stream. Of course this is not as accurate as Realflow but can be useful for some conditions.

Video tutorial with subtitle:


0. Scene setup:
The basic idea is to use Superspay as a particle source, with proper spacewrap binding, the particles can move more or less like water. Then we use Frost to create water mesh from Superspray.

1.  Create a Superspray in your scene:

2.  Create a Drag force:

3. Create a Gravity:

4. Create a wind:

5. Bind all the forces (Drag, gravity and Wind) to your superspray. Create a Frost and pick up the Superspray. Change the type to "Anisotropic"

6.  Frost: tweak around those parameters till you get good results. That's it! sooooo easy ; )

Tutorial: animated ribbon with thinkingParticles


Author: Hammer Chen

In this quick tutorial I will show you how to use "vertex to particle" operator in thinkingParticles, to simulate animated ribbon (or cloth) wrapping around any geometry.

Video tutorial: animated ribbon with thinkingParticles 
Please note this video tutorial contains no audio but you will see subtitle on youtube.





0. Basic scene setup:

  • one lowpoly ribbon mesh object (create by using retopology tools in 3ds max)
  • one female object for collision
  • one animated mesh, move along ribbon mesh, which control region of ribbon to be activate
1. Create two group in tP: ribbon and ribbon_activate

2. Vertex to Particle will generate particles base on selected object (in this case is the ribbon mesh), and those particles will control the movement of ribbon, acting as joints (or spring), so the ribbon mesh can act like cloth.


3.  InMesh operator will control which region of particles (on the ribbon) to be activated. Once they are "in mesh", will transfer to "ribbon_activate" group.


4.  Once particles are in "ribbon_activate" group, we can apply all kind of force on it. For example a vortex force.


5. Select the female mesh as source of Deflector, so the ribbon can collide with female body.


6. On top of the ribbon mesh, you can add "turbosmooth" or "shell" modifier to make ribbon more realistic. That's it!
