To successfully sample a Phoenix FD Simulation's Grid channel, the respective channel export should be enabled under the Output roll-out of the Phoenix FD Simulator. If the channel is not present, the TP Sample operator will return a value of 0. You can find more information about the ranges of the grid channels in the Grid Channel Ranges page. |
Velocity [ vector ] – Returns the Velocity vector at the sampled Position.
Smoke [ scalar ] – Returns the value of the Smoke channel at the sampled Position. This is usually in the range of 0-1.
Temperature [ scalar ] – Returns the value of the Smoke Temperature channel at the sampled Position. This is usually in the range of 400-3000.
Fuel [ scalar ] – Returns the value of the Fuel channel at the sampled Position. This is usually in the range of 0-1.
Color [ vector ] – Returns the RGB channel value at the sampled Position.
Viscosity [ scalar ] – Returns the Viscosity channel value at the sampled Position. This is usually in the range of 0-1.
Speed [ scalar ] – Returns the Speed channel value at the sampled Position - the Speed represents the magnitude of the Velocity and is usually in the range of 0-2000.
