Controlling Melting Phase Change Simulations
MetadataShow full item record
I have developed a set of Houdini Digital Assets (HDA) to control phase change in materials that melt. Examples of real world materials that exhibit these phenomena include melting candles, molten steel, etc. The purpose of this tool is to provide artistic user control when animating these materials. The user can provide an object model as an input to the HDA, which can then be split into multiple sections as per the user’s needs. The user can then specify attributes such as temperature, viscosity, and a melting rate for each section. The object is then filled with particles to resemble a particle based fluid object, with each particle inheriting the attributes of the section it belongs to. When the simulation is run, two conditions control the behavior of the phase change at each timestep. First, the particles melt only at the rate specified for their section. Second, the particles from one section do not mix with those from another section. These conditions are implemented using custom digital assets in Houdini that I developed. Once the simulation is complete, the user is able to combine the deformed meshes of each section into a unified animated mesh and proceed with shading, lighting, and rendering.
