It's a better idea to use the Win32 API Sleep() and SleepEx() functions for delaying instead of huge incremental loops:

C++

VOID
Delay(INT iMilliseconds)
{
    SleepEx(iMilliseconds, FALSE);
}

Clamp Texture Address Mode

Microsoft DirectX 9.0 / C++ Question about Setting Sampler State / Clamp Texture Address Mode.

How can I get a SetSamplerState to effect a specific custom vertex and not the whole entire scene?

For instance, I created a scene with 3D objects and stuff completely surrounded by a Skybox cube.

I'm trying to get the following code to effect my skybox cube face textures only, and not the rest of the scene. Confused | :confused:

// Clamp Texture Address Mode.
g_pD3DDevice->SetSamplerState( 0, D3DSAMP_ADDRESSU, D3DTADDRESS_CLAMP );
g_pD3DDevice->SetSamplerState( 0, D3DSAMP_ADDRESSV, D3DTADDRESS_CLAMP );

The code works great as far as getting rid of those noticeable seams in the skybox, but it also messes up the rest of the stuff.

Any help would be greatly appreciated.. Thanks! Thumbs Up | :thumbsup:

In school I had not heard anything about vectors and matrices yet, so I figured the whole transformation and projection stuff out with regular trigonometry. What a triumph when I had my first tetrahedron choppily rotating on the screen Smile | :)

What kind of an answer did you expect? The general subject fills many books, beginning with a few chapters in a math book. But if you are looking for a less theoretical way to get started: Try this[^]

Anyway, that link makes getting started about as easy as possible, but you will still have a lot of learning and thinking before you.

Animation in borderless window

Hello everyone!

What i want to do is to make an animation of a female character that appears on SCREEN and does everything it was supposed to do during animation.
The MAIN problem that i have no idea how to do this on the screen, without any borders of audio/video player. Closest EXAMPLE is VHGD aka VirtuaGirl player - girls walk on your screen without any border of the player (my version is NOT porn, it is rather gift).
Animation will be done by myself, all i ask is how to make it look like a VHGD.

How can i perform this using C# or any 3rd party libraries/ect?

Take a look at this[^] for a great tutorial on Windows skinning: i.e. showing the content without the frame and border portions.

Hello Richard!
The first thing is - thank you for the reply. I`ll look into that right now (well i`m working my 16th hour now Smile | :)

)
If i get it right, i just need to use some sort of player to play usual AVI/H.264 file with animation... (of cource using technique you`ve provided)
Another question... this animation is "Advisor" - a copy of a real user actually that performs some actions like find document, search the database, edit the tables in the database and even dancing a bit. Is there any way to manipulate the AVI file to trigger events according to gestures?
For example, advisor raising it`s hand in the air and windows creates several buttons near advisor`s fingers.

Thank you.

You would need some sort of image recognition software or collision detection, to trigger an event when part of the body hits a certain point on the screen. Sorry, but that is well beyond my knowledge and experience level.

Thank you anyway, image recognition can be done using AForge library and neural networks... For some weird reason i`m occupied in program for image recognition (motion detection). Thanks a lot for a pointer to obvious thing! Smile | :)

Thank you for the reply Alisaunder!

This is very simplified, i`m doing professional animation of model in 3dsmax 2012, then texturing via photoshop, adding effects via AfterEffects and... voicing it via Audacity...

What you`ve suggested came to my mind in the first place when i`ve decided to do such a thing Smile | :)

But brain came to conclusion that quality is better.

I have protected List<vertexpositioncolor> vertices = new List<vertexpositioncolor>();

Now I added 8 VertexPositionColor for a cube and I can see that cube. I like to rotate it around x-axis or any axis. How this can be done?

Please note we are not changing the camera location.
All opration must be done on cube not the camera.

Your answer will be very much appreciated.

Best regards

For regular photo editing you could use either paint.net[^] or gimp[^].

Not sure what features they have for web design, but they're a start.

Graphics Plugin for Liquidity Risk Software?

StaceyL21-Jun-11 10:46

21-Jun-11 10:46

Hi all (sorry if this is the wrong forum). In my work (I'm a financial planner) I use liquidity risk software ^ (like this one) in order to evaluate different types of risks in different financial scenarios. These types of programs are genrally very useful, except that they usually spit out data in a difficult form to read. Sometimes they do display data visually, but the quality and readability of the visual aid is usually low.

I was wondering: is it possible to write some type of plugin or external software that would process this data (automatically or as close to that as possible) and present it visually in a more friendly way? I'm not a programmer myself, so I'd appreciate it if you could point me in the right direction. Would this only apply to open-source software? Does this sound plausible? possible? already outdated? Smile | :)

Thanks!
Stacey
