1. Let's create a can and some condensation drops. Stretch out a disc and BEVEL it to create the can. The drops of condensation can be created easily; create 1 point polygons from the point of the can's surface and scatter the surface of the can with Jitter. See Can.lwo and candrop2.lwo.
2. Load each object
in Layout and open LW_MotionDesigner. Select the drop object
candrop2.lwo from the Object panel, and switch Target ON. Also, select
the can object can.lwo as the collision object, and switch the Collision setting to
ON.
3. Set the parameters required for the surface
on the Surface panel. Since the drop object (SPP) is made
of particles, only the Weight and Resistance settings are valid.
Set Weight+-(randomize of weight) for the scattered particles. In
this example, the weight varies between 0.5 and 1.5.
4. Let's set the surface of the can object
(can). Set the collision parameters for the motion of the drop
object on the surface of the can object. The values are defined by trial and error:
Skin Thickness=0.001, Friction=10, Bind Force=1, Fix Force=1 (described
below).
Bind force: The power to stick to a surface. This power moves the points of the target object along with the surface of the collision object.
Friction: Frictional resistance that works when there is a Bind force .
Fix force: The friction power that works when the bind force
is valid. The target object is fixed on the collision object's
surface under the specified value. (static friction power)
5. Let's set the wind and gravity. We'll need gravity to make the particles slide down the can's surface.
The scene file is mdc07.lws.
6. Start the calculation. If you are satisfied with the result, save the data in a file. Use the SAVE MDD button to save the data from the calculation into a file.
7. Go back to Layout and open the Object properties panel for the drop object (candrop2.lwo). Select MD_Plug as the displacement map plug-in and load the saved file.
8. Manipulating the time slider should animate the condensation drops. Apply HyperVoxels for the rendering of the condensation drops.
