Thanks for the link Pete, the software looks really good.
Anything that is easier to use than Blender will make me a very happy man at the moment  .

Performing quantum physics with a nail brush and a small dog is easier than using Blender. I do a lot of 3D work and I have problems with Blender. I far prefer to use SoftImage|XSI and Maya to do the work. If you had the money, I would recommend Cinema4D because it is by far the easiest of these applications to use.

I posted this in the C# forum and then saw this forum on Graphics..(probably is better placed here, please excuse the double post)
I'm trying to draw lines that will show up as overlays on top of the buttons that I am drawing. The buttons are just standard buttons with images on them, but they occlude the lines when I draw the lines in the Form on paint method. Is there a way to paint the lines after the buttons have been drawn, in order to make the lines visible on top of the buttons?
I thought of a transparent form overlayed that I could draw to, but I thought that this would stop me from interfacing with the buttons.
Any Ideas?

Painting on the form doesn't work, because all form drawing takes place on a layer behind the controls. I see two possible solutions, depending on what you're trying to accomplish...
1) If you just need to draw something on the button itself, try subclassing the button and inserting your own OnPaint code (After a base.OnPaint call)
2) If you're drawing on both the form -and- the button, like an arrow pointing to the control, your transparent form idea might work.
It might take some tweaking, but you can override the WndProc method to pass the WM_NCHITTEST message (I think that's the one), always returning the value for Nothing (I think the constant is called HTNOTHING).
Windows calls this when the user tries to interact with something, to determine which process/thread/control should receive the event. This basically tells it that your form isn't really there, as far as input is concerned.

 Hey friends..
CDC::Arc/CDC::Pie are not supported in Windows CE..
I have tried to draw Arc using simple for loop and x = cos(Angle) * radius...
and then CDC::SetPixel used to Glow it...
but
there is Aliasing problem...
Is there any efficient Algorith to Draw Arc/Pie
Thanks in advance...:

Hi!
I having a bit of trouble with drawing an arc and I hope somebody
here could give me a hint.
What I want is to draw an arc given the following parameters: a
bounding box (x1,y1,x2,y2) and a start- and end-angle.
The center point of the arc is the same as the center point of
the bounding box, and the start- and end-angle determines how
long the arc should be.
In example, a square bounding box and a start-angle of 0 and end-
angle of 360 will give a perfect circle (the inscribed circle of
the bounding box), while a "squashed" box and angles of 110 - 200
will give a quarter of an equally squashed circle (starting at 110
degrees).
Moreover, I would like to draw filled arcs (like a pie slice)
as well.
Can anybody give me a hint or an algorithm to look at? I've looked
at the normal Bresenham circle algo and think it should be possible
to adapt this, but I've been unsuccessfull so far.
WinCE Does not support MFC's ARC/Pie .

Hi!
i would like know about the possibility of programming 3d graphs in vb (6 if is possible) without use directx, i know what is possible in OpenGl, but i not know a good about this theme, someboy can tell me where i can found more information?, thanks very much for your help.

I have never attempted it, but you can download the vb sources from Nehe and "try" them to see if they match what ever level VB you are attempting to use. http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=05[^] (scroll to the bottom for all the sources for the same project)

In one of my project i have to create the sketch of human face by combining diffrent parts of the face but i have n idea how it can be done please guide me in detail

My first thought would be draw the sketches of the face parts on paper, cut them out with a scissors,
and arrange complete faces by moving around the pieces of paper on your desk/table.
But I suppose you want to do it programatically. You could do something similar.
You may have trouble finding volunteers here to do this for you (guide you in detail).
If you have a plan and break it down into steps and have trouble with certain specific
steps, you'll probably get much more helpful response here 
Good luck!

run down to your nearest art store, get a book on drawing the human face. This breaks down the face into percentages of the head. Do the same in your program.

How many of you think this will work. I am skeptical, but intrigued just the same.
New ATI FireGL boards[^]
Supposedly they have an auto-tuning driver that tunes performance based on how you are using it at the time. It sounds nice, and looks nice on paper.... but I am curious if it would actually work consistently well. I imagine you could take any test case and it would work, but a full application with variety? would it have to be constantly rebalancing and retuning? would it just take its best shot, make a few tweaks and give up?

Probably not a lot different that what peephole optimizing compilers do with ordinary code. That technology is pretty mature.

Try creating a single path, like the outline of a C that is almost closed on itself,
then fill it.
If necessary, use two such C paths, one a mirrored image of the other.

Dear All Hi,
I have a dialog on which there is an image. Now I want to place another smaller image on the previous image. This new image should be semi transparent i-e see through. I want to ask u people that how can I make this new smaller image (which I have placed on the previous image) semi transparent? So that the image beneath this new smaller image can be seen through it.
Thanks in advance.

One way is to use the GDI AlphaBlend() API to draw the semi-transparent image.
Another way is to use GDI+.

The GDI+ code that will make the image semi-transparent is to create a custom color matrix. This topic is too lengthy to get into specifics but here is some sample code the will get you started:
//Define a color matrix that has 60% transparency
//The value 0.6 in row 4, column 4 specifies the alpha
float[][] matrixItems = { new float[] {1,0,0,0,0},
new float[] {0,1,0,0,0},
new float[] {0,0,1,0,0},
new float[] {0,0,0,0.6f,0},
new float[] {0,0,0,0,1}};
ColorMatrix colorMatrix = new ColorMatrix(matrixItems);
//Now we need an ImageAttributes object
ImageAtttributes imageAtt = new ImageAttributes();
imageAtt.SetColorMatrix(colorMatrix,
ColorMatrixFlag.Default, COlorAdjustType.Bitmap);
//Here, we will now draw the image using the imageAtt
//You will need to have a graphics object created. I am
//using a graphics object with a var name of "g"
g.DrawImage(
myAlphaBitmap, //the image to be made semi-transparent
new Rectangle(10,10,10,10), //destination bmp size
0.0f, //start drawing from the XPos
0.0f, //start drawing from the YPos
myAlphaBitmap.Width, //draw all of the original width
myAlphaBitmap.Height, //draw all of the original height
GraphicsUnit.Pixel, //specify the graphics unit
imageAtt); //use our custom imageAtt
//release system resources
imageAtt.Dispose();
//End of code----------------------------
Hopefully this will get you started in the right direction!
Cheers!
Richard
may your code be error free

Hi All,
How to calculate the total number of vertical lines and the total number of horizontal lines in a .png file using VC++
|
|
|
|

If all else fails, you can read it using GDI+. However, I'd imagine the width and height are part of the metadata you could read with some research into the file format.

Can I convert maya binary file to .obj file...If so please tell me how can I do that.I only have maya learning edition.
thanks in advance

What are you hoping to achieve ? An obj file is a code file, and a maya file is surely not code, but data ?
