Panoramas

What if the image was really wide, such as a panoramic photo that you can take with your phone? Let's try this and map it onto a cylinder.

I was in Los Angeles last year. I hiked to the top of the Hollywood sign, where I took two 180-degree panoramic images with my phone, and later I quickly stitched them together in Gimp. The Hollywood.png image is included with this book, or you can use your own panorama:

Putting it together, using the following steps:

1. Move Sphere 2 out of the way and set its Position to (-3, 1.5, 0).

2. Create a new cylinder by navigating to GameObject | 3D Object | Cylinder, set its Position to (0, 1.5, 0), and name it Cylinder 3.

3. Set the Scale to (2, 0.5, 2).

4. Disable its Capsule Collider component by unchecking the checkbox.

5. Drag the Hollywood texture onto the cylinder.

6. Ensure that the Cylinder 3 object is selected. On its Hollywood material component in Inspector, navigate to Shader | Custom | InwardShader.

A default cylinder in Unity is 2 units tall and 1 unit wide...
