haven't tried it... sounds pointless at the moment... but it's cool to know thats possible... especially because DirectX 10 has certain features, like programming on the GPU... then again do we want to merge them... and if we gonna use DirectX at all, why use OpenGL to that effect... unless you want the engine to be semi cross-platformable... in which case, just use DirectX in class that has the same polymorphic ability....
Once again... why merge 'em?
strange...

This was a failed attempt to create one non-competing standard for all platform graphics, replacing both DirectX and OpenGL. It failed because of the power struggle within the committee. Sun still holds a grudge against MS and MS still holds a grudge against a few others. The idea was that without the competition they could work on creating a super set of functionality on the scale of a full scenegraph as well as low-level functionality. The project tore itself apart internally and the result was we still have DirectX and OpenGL as competitors for "some" markets. Some meaning that cross platform there still is no choice.
In OpenGL 2.0+ you can do some GPU programming. It at least doesn't prevent you, you even have a choice of GPU languages depending on your personal favorites (CUDA, Cg, OSL, etc.). I've been doing GPU programming using vendor extensions since 1.5 was released.

Hi. Is it possible to embed DirectX application in a C# Windows form? The problem is that the application is written in C++.
|
|
|
|
|
Due to DirectX being involved, more than likely not.
|
|
|
|
|
I don't know about embedding applications in forms, but...
The newer/newest DirectX SDKs include separate documentation for managed languages.
The info should be there.

Hi,
Im hoping someone here can help...
I am involved in a project that needs to perform some image analysis on an image to interpret results. The functions I need are as follows: scaling image, image rotation and finally analysis at a pixel level. We are running on WinCE and coding with C#. I am able to find image processing libraries for WinXP which unfortunately don't work on WinCE due to the cut down functionality in Compact Framework 2.0.
I haven't been able to find a WinCE compliant package. Maybe someone here knows of one? Any other suggestions?
Hoping for some leads... 
Regards,
Myron

For a camera which support DirectShow, I can easily get it used via DirectShow, preview video, capture image, record, and so on. Now my problem is I want to know which usb controller and port the camera I'm using is conneted to. I can also get all usb controllers and usb cameras and their connection map via WMI, but can not match the same usb device bewteen DirectShow and WMI. Is their a identifier for me or some way else?
Thanks

hii... i'd like to ask if someone know how can i read 3 DIM vectors valuse of (static type) from file(any external file on any drive of PC) using C++.. my application is programmed by C++ with OpenGL.
regards

how are the vectors defined... generally I have a vector < some3dstructure > storage. and then I simply read into some3dstructure and then push_back(some3dstructure) into the vector. This makes it real easy to read/write binary data. Text data is not really a little more difficult, but rather just a few more steps to keep track of and get right.

Thankx El Corazon for Ur perfect opinion. i was looking for efficient way to read static info. from a file for program generality instead of reading binary data directly (this what i did in my program).Ur opinion is very nice from phelosophical view too  .

they are not that much different. A routine for processing the vector information can in its simplest form be binary read/write. With minor changes you can use routines to provide an interface to/from the binary form to XML, or other text formats, or any format for that matter. They all have generally the same inforamtion, they simply put it in different forms or locations within the file.

thank U again El Corazon for UR rich information about my question.. frankly, i'll avoid the complexity and errors which may be accured when data r read from file. both of UR opinions are satisfactory and perfect.. I have built my program upon UR first opinion, i'll keep UR second perfect suggestion for future work .

I created a charting control for work in ASP.NET, and so far, they are thrilled. It has a bar chart, and a pie chart. Now they want a line chart (like a vertical bar). I have it working, but now they want each bar to look 3D.
Each item is passed into a collection on the control. An item consists of a color and amount. The chart is built by the percentage of each item in the total of all items.
Now they want the line chart (vertical bar) to have a 3D feel. I was able to get the 3D look, but I'm having a problem determining the values for the lighter and darker parts of each item. I need to figure out a lighter (and a darker) color for the passed value.
For example, the bar color would be red. For the shadowed part of the bar, I need a darker red. For the top of the bar, I need a lighter color. But since each item color is being passed, I need to determine these colors on the fly.
Something like GetDarkerColor(PassedColor) would be great. I just don't know how to determine these values.
Any help would be greatly appreciated.

Hi,
you could convert to HSB (hue, saturation, brightness) using Color.GetXXX() methods,
adjust brightness a bit, (watch out for over/underflow)
and convert back. You need to write that part yourself !
This article[^] is my preferred article for june and may help you.
BTW in the Java world GetLighter() and GetDarker() (or something of that nature) do exist.

hey...
need help in 2D drawing ...I want to add drawing ablity for elliptical curves, arcs and ellipses...most of the tutorials i have seen just draw static curves..
I want the drawings to be based on points specified by the user(through mouse clicks) but I having a little trouble in drawing circular arcs using three points(like in AutoCAD)...
any help will be appreciated
thanks

Create a second bitmap with the same dimensions which you don't display. Give each unique area a unique color.
The next step is, when the user clicks your bitmap get the mouse coordinates relative to your bitmap and use these coords on your internal map.
DWORD ID = GetPixel( x, y );
switch ( ID )
{
case 12: //South African;
}
