#5113675 Viable 3D text rendering solution for DirectX11

Posted by on 02 December 2013 - 12:43 AM

I was searching to find a suitable method for rendering text in DX11.

http://rastertek.com/dx11tut12.html was best way but it has some limitations and extra works:

1-Creating Font atlas for an artist is a hard work.

2-This sample did not used some Dx11 ability such as Geometry Shader witch is very suitable to rendering font.

3-This sample implements text in screen space not in world space.


also I do not recommend that you use this method :


This lib create an extra device 9 or 10 to create DirectDraw thus it is a 2D font system and you can not use some debugging tools such as PIX and VS 2012 Diagnostics.

One simple way is using an extra Render Target that stores all tiles INDICES or IDS and when mouse clicked or moved over each tile then sample the render target witch Index or id has been picked.

In this method remember that Index or ID must pass as a pixel shader constant NOT as vertex shader constant and then pass to the pixel shader.


I'm using this method in Dx11 it works very nice also i'm using compute shader to pick ID and world space position of a pixel.

#5043893 How to build mesh position Matrix from COLLADA file?

Posted by on 17 March 2013 - 12:48 AM


try this : 


Matrix Trans = Matrix.Translation(5.463,0,-20);

Matrix RotX = Matrix.RotateX(DegreeToRadian(90.7396));

Matrix RotY = Matrix.RotateY(DegreeToRadian(0));

Matrix RotZ = Matrix.RotateZ(DegreeToRadian(0));

Matrix Scale = Matrix.Scaling(1,1,1);


TransformMatrix = Scale * RotX * RotY * RotZ * Trans;


This worked for me with XSI exporetd Collada.

i am using the following codes in my programs:

in Program class :

    static class Program
        static int Main()
            var frm = new MainWindow();
            while (frm.Created)
            return 0;

in MainWindow Class:

public partial class MainWindow : Form
    //RenderPanel is a Panel Control for Rendering the contents
    public IntPtr RenderPanelHandle { get { return RenderPanel.Handle; } }
    public MainWindow()
    public void UpDate(float dt)
    public void Render()

the following code create a Device that render the contents in RenderPanel:

SlimDX.Direct3D9.Device d = new SlimDX.Direct3D9.Device(direct3D, 0, DeviceType.Hardware, RenderPanelHandle ,
                                                                    CreateFlags.MixedVertexProcessing, pp);

before using Pix you must uncomment DrawPrimitives.
also i think is better to use DrawIndexedPrimitives and create IndexBuffer .

Pix is a good program for debugging Directx app.

1-run pix from directx sdk.
2-Create a new experiment and in program path enter app path or drag app and drop it to pix the experiment window will create with path.
3-select "A single-frame capture of ..." radio button and also set check "Enable draw timing" .
4-now press "start Experiment" by this work your app will start.
5-now press "F12" key and close your app.
6-after closing a window with name of Run will show that it has 4 sub windows.
7-in events window you in find "Frame #" which # is the number of frame that you captured!
8-find DrawPrimitives or DrawIndexedPrimitives and select it.
9-in details window select Mesh tab.
10-in this tab you can see wireframe of you model in 3 states 1:Pre-vertex Shader 2:Post-Vertex shader 3:View port.
11-in bottom we have two tabs PreVS and PostVS .
12-in PreVS you can see vertex data that you created.

try this.

at first use PIX to capture a frame and see the vertex data is correct or not?

#4808417 [MDX] Problem with AdvanceTime

Posted by on 09 May 2011 - 01:19 AM

finally i solve the problem by my self , i'm wonder why no one answered me!!
i write the solution, maybe some one have same problem.
i used the following codes
AnimationController.AdvanceTime(elapsedTime, AnimCallback);AnimationController.AdvanceTime(0, AnimCallback);

this codes cause that callbacks trigger in right times but a big problem still remains.because of some unknown reason CallbackData become corrupt. i think that i have right times, current playing animation and current playing track , with having this informations i don't need CallBackData any more so i set them to null.

#4800912 loading a 3Dc (ATI1\ATI2) texture from file!

Posted by on 20 April 2011 - 01:55 PM

how can i load a texture from file with 3Dc(ATI1\ATI2) format?
or what is wrong in the following codes?
hr = D3DXCreateTextureFromFileEx(pd3dDevice,L"2.dds", 512,512,8,0, (D3DFORMAT)MAKEFOURCC('A','T','I','2'),D3DPOOL_MANAGED,0,0,0,0,0, &texture);

var tex = TextureLoader.FromFile(device, "2.dds", 512, 512, 8, 0, (Format)MakeFourCc('A', 'T', 'I', '2'), Pool.Default, Filter.Linear, Filter.Linear, 0);

the format of "2.dds" is ATI2.
for more information i can create texture with this format but i can not load this format from file!!
