It did seem odd to me too, which was why i didn't want to put it down to numrical drift immediately.
The reason could be that every other rotation was only a few milli-radians in magnitude - its a...

You could try looking on the websites of programming recruitment agencies and see what qualifications job descriptions ask for. Generally, they don't specify a degree - it just has to be numerical,...

Thats fine. All I was saying is I already have more physics books than I care to own :)

I've got an excess of physics books, especially since I just finished my physics masters degree today :D

(Accumulating in the quaternion worked, accumulating in the vector did not. guess thats the...

Thanks for the suggestions. As I said, this is a physics simulation not a game so I don't have to transform through world->view->projection each time, I just work in world space with physically real...

I'm accruing scattering events through the simulation, which are generated randomly from a scatter distribution. So the final oritentation is history dependant and that history is rather too long to...

Terrain rendering is a favourite subject of mine, so i'm just going to chuck in my 2c worth.

Good batching is the most important criteria for graphics cards performance, followed by efficient use...

hi all,

I'm using quaternions to make a lot of small rotations, but after quite a few (10's) rotations the returned vector starts taking silly values.

The quaternion itself is generated fresh...

As expected, I was being a donut. I had set the dialog as disabled in the resource editor by mistake which of course meant it quite rightly didn't respond to user input and locked out the app.

oops, sorry. bad post.

i'm actually using a idle time message loop



while(!done)
{
if(PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE))

hi all,

I have a modeless dialog that isn't responding to the mouse. Presumably, i've not tied it into the messaging loop properly somewhere, but I can't work out where.

I have created the...

The base class constructor does quite a lot of processing on the arguments - enough to make the overhead of passing the arguments through irrelvant.

I'd prefer to not duplicate code in the child...

hi all,

I have a parent and child class. The constructor for the parent class accepts three arguments and would correctly initialise an instance of the child class.
Is it possible to arrange it...

thanks for your help, works perfectly.

hi all,

Does anyone know a clean way to prevent the user from entering thier own text into a combo box? I like the drop down menu over a list box style scrolling menu, but need to prevent the user...

hi all,

just wondering if anyone had any suggestions for which sdk to use for preference for video capture in windows? I can only find 'video for windows' in the platform sdk docs, but I have a...

hi all,

is there anyway to pass a (unspecialised) templated class reference through a function? something like :



template <class TYPE> class VECTOR3 {/*etc etc*/};
template <class TYPE>...

As usual, i stared at this for a morning, posted a question and immediately spotted the solution. Needed another * before the 'prev' variable name (have to admit, i find it counter-intuitive that you...

hi,

I'm having troubles with the following class declaration:



template <class TYPE> class LList
{
public:
LList();

Hey,

I want to set my (win32) application to use the winXP visual styles and Comctl32.dll version 6, which judging from the documentation I need to do with a manifest.

I'm using visual c++...

thanks for that. i eventually solved the problem for myself by downloading the visual studio 5 beta and using that :D

i may well go back to vc6 now it is an option though.

hi all,

did anyone see link errors like these :


Linking...

cool, didn't know about that one.

should the program be CoUninitialzise()'ing to?

Thanks for that!

Hi all,

Are there any system supplied dialogs that will allow you to browse for a folder/directory? (like in winamp when you add a directory you get a dialog that just shows the folders on a...
