OpenVDB Files

Table Of Contents


Volume Rendering

The Redshift for Katana plugin has a custom RedshiftOpenVDBVolume node to support the rendering and visualization of OpenVDB volume files. OpenVDB is an open source hierarchical data structure for volumes.  It has become the standard for interchange of volumetric data between applications.



The RedshiftOpenVDBVolume node has the parameters to set the OpenVDB file and control the volume pre-visualization in the Katana viewer. The RedshiftObjectSettings node can be used with the volume locations to set the visibility options.



Volume Shader

The Redshift volume shader can be assigned to the OpenVDB objects to configure all the shading parameters, including the grids to be used, the absorption, scattering and emission settings, etc.



Volume Instancing

The plugin supports the instancing of the OpenVDB volume objects using the same workflow used to instance regular polymesh or curves objects (the “instance.ID” string attribute or using the “geometry.instanceSource” workflow).
