What is Particle orientation?
Particle orientation imposes a big influence on a clay’s drying shrinkage (a piece will shrink more along one dimension than another). As particles draw closer and closer as clay dries, the mass becomes more and more dense. The clay particles fill in the space between the others (silica, feldspar, etc) in the matrix.
How do you set an object as a Particle in blender?
To add a new particle system to an object, go to the Particles tab of the Properties editor and click the small + button. An object can have many Particle Systems. Each particle system has separate settings attached to it.
How do you use a Particle instance modifier?
The Particle Instance modifier is added to a cylinder object and then associated with that Keyed particle system. When the Create Along Paths is activated, instead of the cylinder location just following the position of the particle, the cylinder mesh is fitted to the shape of the path followed by the particle.
What happens when an object is applied to hair?
When I apply an object to the hair, it doesn’t deform like the hair, it just changes in height. Here’s a sample showing the hair (left) and the same particle system with the “Render” set to “Group” which is some modeled wheat (right).
How are oriented particles used in shape matching?
The novel idea of using oriented par- ticles in connection with shape matching allows us to create com- plex dynamic objects with only a small number of simulation par- ticles. This makes turning a visual mesh into a physical object a simple task which can be performed in just a few minutes.
Where did the idea of oriented particles come from?
The idea of attaching orientation information to particles and the term ”oriented particle” was introduced by [Szeliski and Tonnesen 1992]. They used the additional information to define special en- ergy potentials that let non-connected particles form surfaces rather then volumetric objects.
How are oriented particles used in solid simulation?
The underlying idea is to use oriented particles that store rotation and spin, along with the usual linear attributes, i.e. posi- tion and velocity. This additional information adds substantially to traditional particle methods.
