Structures

This section contains information about the following structures used with Direct3D Immediate Mode.

• D3DCLIPSTATUS
• D3DCOLORVALUE
• D3DDEVICEDESC7
• D3DDEVINFO_TEXTUREMANAGER
• D3DDEVINFO_TEXTURING
• D3DDP_PTRSTRIDE
• D3DDRAWPRIMITIVESTRIDEDDATA
• D3DLIGHT7
• D3DLIGHTINGCAPS
• D3DLINEPATTERN
• D3DLVERTEX
• D3DMATERIAL7
• D3DMATRIX
• D3DPRIMCAPS
• D3DRECT
• D3DTLVERTEX
• D3DVECTOR
• D3DVERTEX
• D3DVERTEXBUFFERDESC
• D3DVIEWPORT7

Note  The memory for all DirectX structures must be initialized to 0 before use. In addition, all structures that contain a dwSize member must set the member to the size of the structure, in bytes, before use. The following example performs these tasks on a common structure, DDCAPS:

DDCAPS ddcaps; // Can't use this yet.
 
ZeroMemory(&ddcaps, sizeof(ddcaps));
ddcaps.dwSize = sizeof(ddcaps);
 
// Now the structure can be used.
