This module combines the Coordinates given as (x,y[,z]) and the dimensions of the field to calculate the index of the point in the data array.

| Name | Type | Description | UI Control |
| x_index | int | x_coordinate of Point. | Slider |
| y_index | int | y_coordinate of Point. | Slider |
| z_index | int | z_coordinate of Point. | Slider |
| dims[] | int[] | dimensions of the field | (none) |

| out | int | Index of the point in 3D |
The module calculates the array index of a point in 2D/3D space. This index can be used to access the data values of the particular point. The data of each point is stored as NodeData in a linear array of values. The CombineCoordinateIndex module generates the index for a point using the dimensions of the field the point is part of and the points coordinates. The user_macro provides a simple user interface that allows the selection of the point in the field using sliders.
in_fld
An AVS field structure. The only part of this structure which is used is the dims[] entry. This defines the dimensions of the field in which the point is located to linearize the coordinates.
x_index
x-Coordinate of the point.
y_index
y-Coordinate of the point.
z_index
z-Coordinate of the point. (3D)
out
The linearized index for the point in the 2D/3D field
The module calculates the array index of a point in a field. This can be used if one wants to access the data value of the point (32,24,45) in a 64x32x50 data volume. This module calulates from the coordinates (32,24,45) and the dimensions array {64,32,50} the linar index 93728. This linear index is the index of the data values for the given point in the NodeData-arrays.
