Flying Cards



This is a Houdini particle simulation. Models of cards are instanced on a particle system. A curve was drawn in the outline of the human figure and moved out in the distance in front. Then one particle is emitted per point in the curve. The particles are then grouped randomly into 5-6 groups. Then the particles in each group are given a random velocity and the groups begin to move at different increments in time. This ensures that the cards will not form the shape of the human in the air before they hit the wall.

Breakdown
There is a random rotation applied to each of the particles as they move. Once they hit the wall, they stop rotating.


Here is a previous clip I created to test things like textures, particle behavior, and motion blur.

The card models are given a random texture from these playing card texture files.
