Volume VOP Global Variables VEX node

Provides outputs that represent all the global variables for the Volume VOP network type.

This operator provides outputs that represent all the global variables for the volume VOP network type. There are no inputs to this operator.

The Volume VOP operators, such as Gas Field Vex DOP and the Volume VOP SOP, can process multiple volumes simultaneously. Volumes are bound to specific parameters and all bound volumes are available when processing one volume.

Most of the parameter provided refer to the specific volume currently being processed. The exception is density which is provided for convencience for simple networks.

Inputs

None.

Outputs

Outputs include

P	Position of current voxel.
density	Value of the “density” field at this voxel location.
ix, iy, iz	Voxel indices, ranging from 0..resolution-1.
resx, resy, resz	Resolution of the current volume.
center	The center of the curent volume.
orig	The bottom left corner of the current volume.
size	The size of the curernt volume.
dPdx, dPdy, dPdz	These vectors store the change in P that occurs for each step in the x, y, and z voxel indices.
BB	Position inside the bounding box of the volume. Each coordinate ranges from 0..1.
Time	The global time at which the volume is being evaluated.
Timeinc	The timestep currently being used for simulation or playback.
Frame	The current frame being processed, note this can be fractional.
