Page History
This page provides information on the Phoenix Grid Texture (PhoenixFDTexture).
Overview
...
The Phoenix Grid Texture loads and exposes a Grid Channel of a selected Phoenix Simulator as a procedural texture, which can then be used to shade the simulation wherever colors are needed. It can be created from the Hypershade.

When doing Liquid simulations, Phoenix populates the grid Velocity channel only for cells / voxels inside the liquid volume - empty (air) voxels contain no velocity information. To generate velocity information for the empty voxels, enable Simulate Air Effects under the Liquid Dynamics rollout of the simulator and re-run the simulation. |
...
Color Offset | output_offset – Multiplies the color output values of the Grid Texture. The values are first scaled by Color Scale and then the Color Offset is added.
...
Rescale Grid Channel – Rescales the output values of a Grid Channel to a certain range. The colors you get from the Grid Texture can be meaningful when data that is read from the Simulator is in the 0-1 range. But in case the grid data is negative, the Grid Texture will return black color, or if the data has very large values, like e.g. the Grid Speed which can go up to several hundred, the color returned by the Grid Texture will be pure white. In such cases this data should be rescaled to meaningful color values, which usually means rescaling it to the 0-1 range. You can find out more info about the Phoenix Grid Channel Ranges here.
