# Remap Spherical Field

## About this Block

**What it does:** Uses a Remap function to transform a scalar field from XYZ coordinates into spherical coordinates.

**Tips:**

* All Remap-based functions are centered on the world origin.
* The Y mapping length input specifies the length of the input field to be wrapped about the Sphere's longitudinal circumference.
* The Z mapping length input specifies the length of the input field to be wrapped about the Sphere's latitudinal circumference.

***

Remap a scalar field into a spherical space. The only values that will be mapped are values along the positive X-axis, the Y-axis between -length/2 and +length/2, and the positive Z-axis. This block will not attempt to scale the field values to compensate for distortion. If the compensation is preferred, use the Remap Spherical Body block.
