 | Volume Gradient | Calculates the gradient of a volume primitive. |
 | Volume Gradient from File | Calculates the gradient of a volume primitive stored in a disk file. |
 | Volume Index | Gets the value of a specific voxel. |
 | Volume Index To Pos | Converts a volume index into a position. |
 | Volume Index To Pos from File | Calculates the position of a voxel in a volume primitive stored in a disk file. |
 | Volume Index from File | Gets the value of a voxel from a volume primitive stored in a disk file. |
 | Volume Pos To Index | Converts a position into a volume index. |
 | Volume Pos To Index from File | Calculates the voxel closest to a voxel of a volume primitive stored in a disk file. |
 | Volume Resolution | Gets the resolution of a volume primitive. |

 | Volume VOP Global Variables | Provides outputs that represent all the global variables for the Volume VOP network type. |
 | Volume VOP Output | Simple output variable for Volume VOP Networks. |
 | Voronoi Noise | Computes 1D, 3D, and 4D Voronoi noise, which is similar to Worley noise but has additional control over jittering. |
 | Water Surface | Simulates marine water of variable depth and visibility. |
 | Waves | Simulates rolling waves with choppiness of various frequencies, and outputs the positional and normal displacements as well as the amount of displacement. |
 | While | Runs the VOP nodes inside its subnetwork as long as a given condition is true. |
| Wire Pattern | Returns float between 0 and 1 which defines a wire grid pattern useful for simulating screens or visualizing parametric or texture coordinates. | |
 | Wireframe | Implements a wireframe shader and outputs the final, lit color and opacity. |
 | Wood | Simulates shiny wood grain. |
 | Wood Plank | Simulates anti-aliased wooden planks. |
 | Worley Noise | Computes 1D, 3D, and 4D Worley noise, which is synonymous with “cell noise”. |
