# How to map a bitmap onto a curved surface

## Objective:

Applying a bitmap on a curved surface.

## Applies to:

* Texturing
* Debossing

## Procedure:

1. Import the image using the **Import Bitmap** block.

2. Apply the Bitmap to a plane using the **Map Bitmap to Plane** block.

3. Import the custom block attached below:

* [CB - Remap Spherical Field Z](https://ntopology.box.com/s/dyfefserxqs0dyls0vytxz9y7uqxssxs)

4. Use the **Remap Spherical Field.**

* Drag and drop the color Scalar field from **Map Bitmap to Plane** block.
* X mapping length is the length chip on the **Import Bitmap** block.
* Y mapping length is the width chip on the **Import Bitmap** block.

5. Set up the **Sphere** you wish to apply the Bitmap.

6. Use a combination of **Offset Body** and **Mix** block to deboss the image.

7. Use **Set Body Bounding Box** to view your final implicit.

And that's it! You've successfully applied bitmap on a sphere.
