Dynamic Surface Emissions in Houdini FLIP


Recommended Posts

This another video about small scale sims using FLIP/PIC method for dynamic simulations. This time I have developed a dynamic surface emission system to reinforce tendril emission over any surface, no matter if its deformed or transformed; You can control the tendril emission reinforcement withing a time or frame range, number of particles, initial velocity, etc. In the preview when a particle's drop gains the enough volume, it activates the dynamic emission and soft trigger an influence force that makes the drop raise and create the tendril's emission dynamically. So with this setup its possible to create condensation like sims for example, but as a true fluid sim (still WIP).
There is also an update to my Tension pipeline for small scale FLIP/PIC sims, now there is a new implicit drag force that gives control over the "fluid/air" like interaction, so there is a better shaping behavior of tendrils and drops; Also you can invert the force to reinforce tendrils creation (this is another method that replaces the usual velocity alignment method in the Tension pip
