This app is an iPad rendition of "Kleinian_Jos_001.frag" linked on that page.
Update ----------------------------------
Added Default Recordings.
I have always faced this problem: What is the easiest way to provide a bunch of recorded datasets
along with the app?
This latest posting shows the method I chose:
Two new funcs and a list of Strings.
-
You set a breakpoint in the code, alter a variable value, then continue to call a new routine that
saves all dataset recordings as a list of base64 strings, and prints this list to the console window. -
Copy/Paste that source code to SaveLoadViewController.swift
-
The second new routine is called when the Save/load dialog is loaded. It checks whether any saves exist.
If not, then this is a new install, so access the base64 list to Save the datasets to the users' sandbox. -
Simple and automated, and easy to paste into all the other apps..
Update ----------------------------------
Added Rotate: Object automatically rotates for better viewing.
Added Morph: Selected params automatically cycle.
Added Stereo: My old favorite cross-eyed stereo viewing.
Added Help: Short summary of the the widgets.
