3DPocMod by Antony Scerri
===================================
Release : Version 1.4.3 30th October 2002

Introduction
============
This is an early Beta of my 3D modeller for the PocketPC. Right now it allows you to create objects with points and polygons. Surface colour attributes are supported but not completely functioning right now. 

System Requirements
===================
PocketPC Devices
 o ARM running PPC2000 or PPC2002

Microsoft ActiveSync 3.0 or greater

Installation
============
To install it you can copy the EXE file to your device. 

How To Use It
=============
Simply click on the file to launch it.

Once running you have several features to hand. You can create news files, or open existing files. Saving a file will save in a proprietary format for this application. Support for additional formats will be added later.

There are several tools to work with your model. You can switch between point and polygon mode which will effect how the tools behave. Tools you have are :-

 o Select points or polygons
 o Move the current selction
 o Rotate the current selection
 o Add points
 o Create polygons from the points, by selecting the points in a clockwise order
 o Clear current selection (points or polygons dependant upon mode)
 o Delete current selection (points or polygons dependant upon mode)
 o Hide points or polygons (based on current selection). And can then unhide them again
 o Edit the surface colour through the surface editor.

At any time the tools will work on all points, and/or polygons if none are selected. 

There are currently several rendering modes. The default is flat polygon rendering as supported by the OS bitmap routines. I have written my own graphics engine internaly which you switch to. This then supports the normal flat rendering mode, with the addition of Z-Buffering for more accurate renderings. Then you can switch to Gouraud shading, or Phong shading. You can switch the view from which you look at your model from one of six front, back, top, bottom, left or right.

It currently supports undo and redo actions, although these may be unstable at this point.

The application also supports an automatic spin to show you your model from all sides. Currently based on my observations it will only be able to spin correctly in flat shading mode, both OS and my internal one. It has worked in Gouraud shading mode in some cases and dependant upon the model size. The current issue is that these devices do not have floating point processors so I have inter fixed point arithmetic, and now need to speed up the renderer.

Uninstall
=========
To uninstall it simply delete the EXE file. It does create some additional registry keys but these are minimal and will be reused if you should install the application again.

Known Problems
==============
Currently the only known problem is with moving your objects off of the visible screen area, this is because the graphuics engine is still being worked on, and is fairly simplistic in its exception handling right now to keep the speed up. This is an early Beta and could crash. Please backup your device before using it.

If you have any problems with this application please email tony@3dcybercorp.com with details of the problem you are having.
