A typical picture update of the project from both aspects, the 3D and the physical interface.
Testing the spike generator for visual feedback on the terrain:

Having acquired a joystick I was eager to try it out in my DirectX project. This is theoretically a very easy thing to do, but of course, it isn’t turning out that way. While the sample project and tutorial instructions are incredibly easy to follow, and the sample project compiles and runs perfectly well, starting to apply this code my own project is not straightforward.
Something which I am now starting to accept is pretty typical of Microsoft’s code is that they do something totally differently to the way that they themselves have said it should be done, and don’t bother explaining WHY.
Nevertheless I shall persevere with adding this to my project with the intention of linking camera control to the joystick, but the responsiveness of the motion will be dependant on the strength of biofeedback signal.
Update: I discovered I was trying to fix an issue that didn’t exist when all that was required was including the dinput8.lib file to the project…

Thanks to Alan for pointing me in the direction of CamStudio, a free video capturing software for your screen, which I have used to produce a slightly better video of my project’s 3D world.
Running both the software and DirectX at the same time was a bit tricky, slashing the FPS from around 120 to 40 but it’s better than using my camera to take a video of my laptop screen!
The water can be manipulated from any point, but for now it is set to only ripple from the centre. When I produce a final visualisation the position will vary, of course based on biofeedback influence.

Since still images don’t quite demonstrate the effects going on in the 3D side of my project, I decided to take a video recording of the liquid as well. It’s not great in terms of quality and could have been composed more fancifully but gives you an idea.

After quite a lot of effort, adding, swapping and killing code I’ve started to get away from having HLSL turning everything a shade of utter grey.
The screenshots show my water mesh which will be one of a few features of this virtual environment which responds to biofeedback data from the avatar’s user.

My Initial 3D avatar model idea mocked up in 3D:
The idea is to represent a more traditional aesthetic of meditation, providing a connection between the project and the field of biofeedback’s origins.
Also the development of the environment and the terrain mesh:

Here is a screenshot of my mobile lights floating around the fish model all wrapped up in a micro-terrain:

Here are some screenshots I took a couple of days ago of developing my mobile lights. I’ve also decided to re-use the fish model for now since I have nothing better to replace it with!
Here is a shot of my first light, not doing very much interesting.
The final lights are completely mobile and have behaviour determined by taking analogue signals from my USB circuitboard. The motion ranges from soothing and gentle to fast and erratic.
