STE Projection Surface

Ability to Create Curved Projection Surfaces

Introduction

STE has a new feature. In the past, STE could only create a transform where the projection surface was flat. In a flat projection straight lines in the real world were straight in the resultant image. STE is now capable of creating curved projection surfaces. Projection surfaces can be flat, spherical, cylindrical or custom curves. This allows the creation transforms which are a compromise between visually unfriendly fisheye views and flat views with low fields of view and low resolution near the edges.

A curved projection surfaces can be used with the virtual camera. The results can be somewhat strange. For most applications it make little sense.
Panels will not stitch together in multi-panel mode. It's not mathematically possible to stitch them along a straight line, it would need to be a curve which the hardware cannot accomplish. It is not disabled as some clients may find good use without the stitching.
It is not applied in linear stretch mode.
