I wanna to draw and without ID3DX10Sprite,below is my idea,

I have created a buffer,only 1 vertex and assign one ShaderResourceView when I draw it,

when it's on Vertex shader I setup a Matrix Resource to indicate it's position,

and I have to setup position info on GeometryShader,

it should be like this

2loop for 2face,3loop for each vertex,assign position data to each vertex

but I have no idea how to get 2d coordinate,

for example I have one image size is 50,50

and I want to draw it on screen position 80,80.

I have using

D3DXMatrixTransformation2D(,,,,,&Pos);

to assign WorldMatrixVariable and multiple it with camera worldView Projection

but I can't see any the image on the screen...

please give a direction to me ,thanks :)

forgive my srupid :)

all I need to do is assign SetOrthographic projection

and  get screen space point

        POINT ptCursor;
        GetCursorPos( &ptCursor );
        ScreenToClient( DXUTGetHWND(), &ptCursor );
