D3D 3D Box - Draw Function

[quote name='RiSiCO' timestamp='1208537000' post='9482']
Hi guys,

i dont know if it is needed by anybody but i searched around 1 whole day on the net for a 3D Box function and couldnt find it. Thats why i carried on with it myself and here are the results.
Its only the Draw function, that means that you need to give your own parameters of your source etc to it. For example bones.


Here is a picture, that you see which points you have to give to the Draw Function, i am not a paint expert but i think its possible to see what i mean.

And the following is the code which you need for the draw function. If you give the parameters correctly it should draw a 3D box around the parameters you give in .

Kod:

//declaration stuff
ID3DXLine  *pLine; //Liner


//here is the functions body
void Draw3DBox(float x_bottom_left, float y_bottom_left, float x_bottom_right, float y_bottom_right, float x_top_left, float y_top_left, float x_top_right, float y_top_right, float x_forward_bottom_left, float y_forward_bottom_left, float x_forward_bottom_right, float y_forward_bottom_right, float x_forward_top_left, float y_forward_top_left, float x_forward_top_right, float y_forward_top_right, int a, int r, int g, int b)
{

    }
}

//following you put in endscene for example:
D3DXCreateLine(d3dDevice, &pLine ); //Create line (put that for example in endscene or whatever you hooked

//and last but not least lets call our function:
Draw3DBox( /*all parameters for example bones*/ );

Of cause its possible to use Vectors on that function but i tried to keep it as simple as i could.
It shouldnt be a problem to rewrite it cause i hope the function and a grasp of c++ is at hand.

In the case there are questions, reply right here,
