Rendering problem

You may find the function:

IDirect3DDevice8::SetViewport(..

handy to achieve this, you need to pass a D3DVIEWPORT8 pointer into it, e.g you could use

D3DVIEWPORT8 view;

D3DVIEWPORT8 old; // Store Current Viewport
m_pDevice->GetViewport(&old);

view.x = 0;
view.y = 0;
view.Width = 640;
view.Height = 480;
view.MinZ = 0.0f;
view.MaxZ = 1.0f;

m_pDevice->SetViewport(&view);

.. Do the presenting of the scene

m_pDevice->SetViewport(&old); // Regig View to old position

Hmmm... sounds like a good idea.. i''ll give it a try 8]

I think what im trying to do is have the rendered scene in say the bottom left corner of the screen, and having a sort of ''HUD'' around it (as opposed to layered over the top).

If my brain was plugged in yesterday I would have mentioned this. DOH! :D

Could the same effect be produced using your method ? or is there a better way for this scenario?

Well, for 2D graphics on a 3D scene, I normally use the D3DXSprite object, using the ->Draw function as it will place images ontop of your 3d display. Another good benefit of using this way is that you can also use the blending of alpha channels to make the HUD opaque, which normall gives a good effect.

E.g.

LPDIRECT3DTEXTURE8 pTex; // Valid Texture With Image Information
LPD3DXSPRITE pSprite; // Sprite Interface

Use :

D3DXCreateSprite(m_pDirect3DDevice,&pSprite);

to create the sprite object ( dont forget to release it in the dsestructor ore when you have finished using it)

1. Clear & begin buffer

2. Setup Viewport for 3D Display as defined in my previous post, and draw the 3d Objects.

3. Draw the scene

4. Reset Viewpoint for full screen

5. Use pSprite->Draw to draw the texture onto the display using screen coordinates, i.e.

pSprite->Draw(&tex,NULL,NULL,NULL,0,&D3DXVECTOR2(150.0f,150.0f),D3DCOLOR_RGBA(100,100,100,100));

this will draw the texture onto the screen at screen coordinates 150.0f horizontal by 150.0f vertical with an opacity of 100, where 255 is solid and 0 is opaque for reference.

6. End & Present Buffer

excellent... I''ll give that a try this afternoon I think 8D

Thanks for your time 8-)
