Iam doing my graduation project and i need to do a project (Design simple dream home ..)which is build 2d home which the user draw( I use c# to program it )and then transfer it into 3D home and allow walk throw this virtual 3d home...
which is better to do this transfer and drawing this 3D home..DirectX Or Open GL ??( I don't no any thing about both.. but i want to learn the best for my project )..
Thanks..

short answer: both, neither, either... take your pick.
Long answer: DirectX is designed for Windows operations and is a closed system, if you are on windows only, and C# only, chances are you will want to use DirectX. OpenGL is designed to be cross platform, and open. There are some advantages of the open system. It is far easier to find your scenegraphs for OpenGL for instance because of the openness issue. OpenGL is defined by committee, where-as DirectX is defined by one Company: Microsoft. There are advantages and disadvantages to both. You know what they say about committees, "a camel is a horse designed by a committee." ATI's got to get their two cents in, so does nVidia, so does Sun, so does... etc. Once everyone has put their two cents in, you've got some odd things. But on the good side, you are generally graphics card agnostic, tests are uniform, and extensions are available to pull in the latest stuff from your favorite vendor. With DirectX there is one way, or the highway, you say nothing, you obey everything. Don't like it? tough cookies, go play elsewhere. The advantages with DirectX is that it is generally efficient, if not sometimes convoluted, both because Microsoft can do anything they want, and they really don't have to listen to anyone else unless they feel like it that day. And of course the big thing for you, DirectX plays well with C#. Not to say you can't do OpenGL with C#, but you will find it usually easier to do DirectX.
OpenGL is also designed to be language agnostic, you will find OpenGL for C/C++ mainly, but also for VB, Delphi, Fortran (yes, you heard that right), Perl, Python, Ruby, Scheme, D, C#, and many, many, many, many more.
You might as well ask which is better, Fuji Apples or Granny Smiths? You'll get lots of opinions, but the real question is what is right for you, and no one can answer that except you. Personally, I prefer Fuji Apples and OpenGL.  Plus I can plant the garden outside the house and make it wave in the breeze.

And Microsoft was part of the original committee. Just shows you really need to be careful letting Microsoft near a standards effort.

Like a lot of Microsoft API's, it appears to be the outgrowth of someone's thesis project. A lot of theory but little thought on what is needed in practice.

DirectX
Pros:
- It's a complete engine that'll handle stuff like audio, input, etc.
- A lot of companies use it, so learning it may land you a job.
Cons:
- Uses COM, so it's inherently slower.
- Windows Only.
- The code required to get things going is bloated.
OpenGL
Pros:
- Cross platform, if you want your games to also work on Macs, Linux, etc.
- Fast and efficient.
- It runs about 10 FPS faster on nVidia cards in Windows (pre Vista that is).
Cons:
- It's just a rendering pipeline, you'll still need to handle things like input, audio, etc. with another library.
- DirectX dominates the Windows arena, and Windows dominates the desktop arena.
I prefer OpenGL personally because I believe Windows isn't the only OS in the world. But, as far as what's really better or not, it depends on your circumstances. If you'd like to get a job in the gaming industry, learning DX may be a good choice. If you want cross platform, OGL is the way. So on and so forth.
And remember, at the end of the day, making a good game has less to do with your choice of engine and more to do with the talent of your team.

Thank you for your wonderful analysis, I will choose to learn DX first
|

I think DX is better for you, you can modify the samples to match your needs

Is there anybody know how can I fetch resources from Uncharted Waters 4, published by KOEI.
I need the pictures in Uncharted Waters 4, thanks a lot!

send in your resume/CV and application to KOEI to be an employee.

hey, it is nothing but the truth. My work is not public access, but does generate public pictures once in a while. I am the only one who has them outside my work. If you want to get access to the goodies, join the team. It's the best way, and you earn a buck doing it too!
and I play native american flute, not guitar.

American humor? Is there any other solution? I'm serious, thank you.

The artwork in the application belongs to KOEI. They produce the game, and their license will be pretty tight, so we cannot help you to rip them off. Sorry, but we don't encourage this type of behaviour around here.

Yeah, I think you are right, but I don't want to steal these from KOEI, I just want to know how to fetch them out, from the technical point of view. It's just my interesting, you know, if I use them in business products, KOEI will trouble me. ^_^

If you use them in ANY product, KOEI will "trouble you". Actually, they'll sue the pants off you. And it's this very reason that makes it difficult to help you. If we tell you how to do this, then you go ahead and use the images anyway, we become complicit in the suit against you by KOEI. Why should we open ourselves up to that kind of liability?

Then write your own program with images you create and learn to rip them that way. Glad I could help.

I need sugge./ advice for video processing for bleow requirement
Person or object will be selected in the first frame of video sequence
manually by mouse. Now the selected object/persion should be segmented in
rest of the frames by the algorithm/porgram.
any souce code/algorithm/ links / suggestion are greatly appericated
Thanks in advance

Hi All,
I am writing an application which try to show PNG file as a dialog background using GDI+
I have successfully using the PNG as background (using Graphics::DrawImage()), however, I found that the loaded PNG seems not apply the alpha channel information. What I should do?
Thanks!

Hi,
Is there any way to get the most common used color of an image (jpg) in C#/VB? I have been searching the for "image histogram" and "image quantization", because it seams like these are the most common terms. No luck yet.
I would like something to categorize images by color.
Best regards

Why? It seams really the best way ...
You will have probally only to perform the algorithms setting thresholds..not more

Hi Russel,
Thanks for the reply.
I am searching for an example or description on how to do it, but haven't had any luck yet.

a simple example for "Histogram":
* convert the image in RGB (same if HSV)
* find min and max value for R ,G ,B in all the image
* quantize (for example using 50 slices per color) the range of values in that min-max interval (for every 3 colors, so you will fix 50x50x50 cubes/volumes)
* then look to the pixel of the image and count how many time a color fall in a cube
* when finished the cube with the greater number of pixel inside is the color that you are seraching
*eleway you can analise separately R, G and B. In this way you will have 50+50+50 linear intervals, not volumes.
