Chapter 16: CMA: Warp Editor

User Warps are applied globally to modify the output display shape. This
chapter describes the Warp Editor and includes a step by step example for
creating a custom warp graphic object.

Overview

The Warp Editor feature lets you adjust Axon HD, Axon HD Pro and DLHD output to match
complex projection surfaces. These forms allow the projection to match irregular surfaces or
quickly produce interesting creative results. The warp editor can also edit geometry directly,
either to create complex holes in surfaces, or generate new polygons based on neighboring
geometry.
You can build a geometrical warp in one of two ways,
1. You can modify one of the primitive shapes provided in the editor. Simple surfaces such as
fabric screens can be quickly built from these primitives. This concept can extend to more
complicated forms, such as rectangular grids with sections cut out, cylindrical surfaces and
spherical surfaces.
2. You can import and edit an .obj file you have created through another application.

Functional Operation

The warp is applied at the global level, analogous to a keystone operation. Editing the output at
the final step retains all layer programming but allows changes to the image as a whole.
Consequently, there is no need to perform major changes of the layer positions if the projector
has moved.
This also applies to changing the projection surface. If one projector is being used on a flat
screen, and, at another time the projector is being used to illuminate a complex form, the warp
would be different, but the content programming will be the same. To achieve this, you use the
warp editor to generate two different warp files. One file is used for the flat screen and one file
for the complex surface. Each of these files would have a unique DMX address associated with it
that you can recall via a control board.
