- Both technologies share almost exactly the same parameter sets and therefore they are explained and discussed together.
- The main difference between these types is filtering. In addition to the common mesh filters, OpenVDB provides very fast → volume filters to shape the mesh.
- OpenVDB meshes are also created much faster than their standard counterparts.
Under → "HyFLIP - Quick Start: Displacement" you will learn how to create Hybrido meshes. The following table explains a few basic terms in conjunction with Hybrido meshes:
...
| Core fluid | This is the → HyFLIP simulation's main body of water. Every mesh vertex carries a "core fluid" attribute that is used by the → “Core Smoothing” filter to create a smoother surface:
|
|---|---|
| Splash | Here we talk about parts of the core fluid which behave like splash, e.g. when object hit the fluid. Every mesh vertex carries a "splashity" attribute that is used by the → “Splash Thinning” filter to create thinner splashes:
|
| Displacement | This structure adds smaller waves and ripples to the surface and is also known as → ocean statistical spectrum. The Hybrido mesh engines displacement filters are used to control how the displacement vanishes in certain parts of the mesh ("attenuation"). |
| Attenuation | There are circumstances where the displacement waves are simply not wanted: Imagine a thin splash, or fast moving parts of the fluid with cresting waves. The attenuation settings allow you to fade and finally remove the small waves based on four properties: speed, vorticity, height, and splashity. |
| Projection Plane | The → HyFLIP domain's viewport representation shows a square with four cubes. The plane's size defines the displacement's scale and tiling, and can also be used to clip unwanted parts of the mesh. When the → "Open boundaries" option is active all mesh parts below and outside the projection plane will be removed. |
| Boundaries | The displacement can be tiled and with the settings of the → "Boundaries" section it is possible to blend the core fluids displacement and the extension tiles in order to get a seamless ocean surface. |
