Implementing a scrollable textarea without using UnityGUI

Questions & Answers

Hey all,

I'm partway through the process of implementing my GUI using Meshes and 3dText, but have hit a major block. I'm completely stumped with how to do a scrollable text area, as I can't see a way of clipping text depending on where the view is looking without using RenderToTexture, which is not an option as I'm using the free version.

This is what I want to be able to acheive:

alt text

Thanks in advance,

Well, just write a clipping shader ;) I guess I would clip after the projection in homogeneous clip space.

You can of course use a second camera (yes, it works in free). You can alter the normalized viewport rect to set the desired area on screen. Let the second camera just draw your text meshes (culling mask) and you're done ;)
