How does Bmax check for DX device capabilities? I've trawled through the source but can't find anything and there appears to be <edit> no <end edit> D3DDEVICEDESC7 type defined. I've created my own and got the information I need using Getcaps but some of the fields are type 'single'. I've defined it as long for now but what does single equate to in Bmax available variable types? In addition a couple of calls return specific objects so I have assigned those fields to object and, basically, discarded them. If I wanted it to all work properly, would I have to define the types for each of these objects as well? <edit> In fact I haven't got this working at all as the contents of each field will depend on how they are defined so I have to get them right.

Most objects are already defined, check out pub.directx :-)

I've already looked in there for the D3DDEVICEDESC7 type and can't find it. In fact I have searched the Bmax directories for it with no result. Is there somewhere specific I should look in pub.directx?

Don't normally like bumping but this might have got lost in all the adverts. Basically, I need to get this... typedef struct _D3DDeviceDesc7 { DWORD dwDevCaps; D3DPRIMCAPS dpcLineCaps; D3DPRIMCAPS dpcTriCaps; DWORD dwDeviceRenderBitDepth; DWORD dwDeviceZBufferBitDepth; DWORD dwMinTextureWidth, dwMinTextureHeight; DWORD dwMaxTextureWidth, dwMaxTextureHeight; DWORD dwMaxTextureRepeat; DWORD dwMaxTextureAspectRatio; DWORD dwMaxAnisotropy; D3DVALUE dvGuardBandLeft; D3DVALUE dvGuardBandTop; D3DVALUE dvGuardBandRight; D3DVALUE dvGuardBandBottom; D3DVALUE dvExtentsAdjust; DWORD dwStencilCaps; DWORD dwFVFCaps; DWORD dwTextureOpCaps; WORD wMaxTextureBlendStages; WORD wMaxSimultaneousTextures; DWORD dwMaxActiveLights; D3DVALUE dvMaxVertexW; GUID deviceGUID; WORD wMaxUserClipPlanes; WORD wMaxVertexBlendMatrices; DWORD dwVertexProcessingCaps; DWORD dwReserved1; DWORD dwReserved2; DWORD dwReserved3; DWORD dwReserved4; } D3DDEVICEDESC7, *LPD3DDEVICEDESC7; into a Bmax format so it can hold the return from primarydevice.device.getcaps. I *think* dword=int, D3DValue=float and word=short. I also think D3DPRMCAPS and GUID will be byte ptrs. However, none of the output looks right. I am *certain* I am doing something stupid.

I think I did this already, i'll just have a check. Nope it was something else. Sorry

tonyg (Posted 2006) [#6]

OK, thanks for looking. BRL, did you ever try this and/or get it to work? I'll keep trying but it's so annoying. <edit> It's OK. I got it... finally.

tonyg (Posted 2006) [#7]

Finally got this working (I think) after lots of hacking about. It might answer some POW2 and Anti-alias questions.
