2 questions about DX
Author
hi:)
i got 2 questions about directx.
1) How can i detect if im in Scene, means if Device->BeginScene() was
called? if i do it twice i get a error (cannot go in scene, if already) but how do i detect it like:
if(InScene == false)
Device->BeginScene();
?
2) if i render a fullscreen pass with zwrite disabled to a render target can i do that without a depth surface or must i attach a depth surface with same dimensions?
thank you guys :D
Your draw code should not depend on whether you are in "draw-mode" or not. It should just assume it, and you should simply get your codepath right:
Simply assume inside your drawing functions that they are actually permitted to draw.
Or what is the strange reason that wants you to depend on such information?
draw_main () { beginScene() drawX() drawY() endSceneI()}Simply assume inside your drawing functions that they are actually permitted to draw.

1) Use a flag to determine if you are inside the BeginScene/EndScene block, even thought I don't know your reasoning, generally BeginScene/EndScene are called once per frame.
2) Yes, you can do that without depth stencil/Z Buffer attached. (I'm sure about DX10, i don't know for sure in DX9)
1. See this recent thread about it.

2) ye thank i hoped so :D thats to confirm that
1) i set a flag now, if BeginScene() succeeded flag = true, if end scene i set it to false. thats crap, but it has to do something with executing a shader in lost device stuff and i have no idea how to do that better, in my normal rendering i only call it once in the render function but this is a exception :D
thank you for your help :D
