Running DirectX with Analogue Input

12th March, 2009

Here’s a screenshot of my visualiser with a model (albeit the tiger model), mobile camera AND analogue input signals displaying in the output, built on the DXUT utility library.

A few more tweaks were needed to get the slower USB interface to read reliably while DirectX pounded my graphics card for every FPS it could get.

Useful DXUT DirectX Pages

Rather than simply tagging this page I thought it more appropriate to draw greater attention to it for myself:

DirectX Coursework 1

22nd January, 2009

Since I thought the fish looked a bit odd without its limbs I’ve decided to post another screenshot, this time of it actually running in DirectX and with the animated parts:

(Only after I took this and put it online did I notice the comments in the background…)

3D Fish is ready for DirectX

13th January, 2009

A quick screenshot of my fish as a microsoft .x mesh file ready to be used in DirectX. The tail and fins are deliberately missing as they are separate models to be animated.

Modelling Fishies

23rd December, 2008

So for my first Programming project I’ve decided to model a fish with moving fins as opposed to the ‘flying thing’ suggestion. But in order to do that I’ll need to make a DirectX fish model…

Here to help are my own goldfish, who it turns out are annoyingly camera-shy.

A good reference and tutorial for making a fish from scratch.

Creating a Visualisation in Visual Studio 2008 (Part 2)

6th December, 2008

Ultimately the point of researching how to create a Media Player visualisation was to be able to include DirectX capability.

After a lot of searching I found information on the subject (http://www.tech-archive.net/Archive/Development/microsoft.public.win32.programmer.directx.graphics/2004-11/0316.html) saying that the Summer 2003 DirectX SDK features a demo being implemented in a Media Player visualisation.

Experimental Analogue Inputs

13th November, 2008

It was suggested that before I go about planning and building a PCB to take biofeedback readings from a person to push as a stream of analogue data into a computer, I should see how easily I can get such information into C++, DirectX and of course eventually media player.
