Volume Rendering

This Actor generates a rendering from the volume data of a quantity directly.

Unlike the other Actors, which view the data only on an extracted surface (i.e., isosurface or orthoslice) or at a particular point in the Domain, this Actor renders the data on the whole volume, hence it is computationally intensive.

To control the rendering speed, you can specify its RenderSpeed setting in the range [1, 10], with 10 indicating the maximum rendering speed but lowest image quality. The smaller you set this value, the longer time it needs to render the scene but the better scene quality it will deliver. Usually, setting it to 5, which is also the default value, can achieve a good trade-off between the quality and speed.

You can also change the color used for the rendering. By default, it is set to white.

Like other Actors, this Actor also automatically extracts the minimum and maximum values of the quantity.

Volume rendering is particularly useful for visualizing smokes. The following example depicts the smoke being released from the Smokebomb* in the Domain.
