Delta Injection (Part 1).

Introduction.

Delta injection is a method of injecting morph targets into a figure from a pose file. The technique seems to have been discovered by Drax back in 2004, below is a link to the thread that started it all, and eventually lead to V3 and all her ilk.

An important thing to understand is that delta injection can't create new targetGeom channels, it can only inject morphs into channels that already exist in the figure* (see note at bottom of post).

There are many different ways to proceed in making a Delta Injection Pose (here after referred to as a "DIP"), but  most methods involve copying the morph channel (or a subset of the channel) out of a cr2 and pasting it into a pz2 template. In other words a DIP is, in essence, just a targetGeom channel packaged as a pz2.

There are also some methods that involve converting a morphed version of the full base OBJ file into deltas, eg "Pozers Little Helper" available at:

*NOTE: Whilst a pose file can't itself create a new targetGeom channel, in P5 and up a pose file can call a Python script that will add a new targetGeom channel, and in P6, PMD files, which can also add channels, can be called from a pose file.
