Week six started with a small practice to make something cool. From a test geometry we scatter points to do an effect like if the geo is vanishing.
With the vop attribute we are able to randomize witch points are being affected by the simulation and also its used to make the geometry disappear when is very small, so it would stop simulating on those particles that we can not see.
Then we create as always the dopnet for the solver. Adding some wind resistance and also modifying the direction of the wind. In this case, we make them go up, against gravity.
Here is the final simulation:
After this small simulation, we learn how to make geometry follow the path of a smoke simulation. We create a smoke simulation like we did previously on different occasions. In this occasion, we create a null at the end of the smoke sim called VOL ADVECT that we are gonna use to make the geometry follow the same sim.
After this, we proceed to create a dopnet for the particles that will follow the sim. And we connected to the VOL ADVECT with the node popadvecbyvolumes. This connects it to the previous volume simulation.
After this, we just have to create a sphere and with copytopoints we replace the particles with spheres and then merge it with the previous sim, and we have the spheres following the smoke sim.
