D3DHAL_DP2SETTEXLOD structure (d3dhal.h)

  • Article

The D3DHAL_DP2SETTEXLOD structure is used to set the level of detail (LOD) for MIP maps when the D3DDP2OP_SETTEXLOD command is sent to D3dDrawPrimitives2.

Syntax

typedef struct _D3DHAL_DP2SETTEXLOD {
  DWORD dwDDSurface;
  DWORD dwLOD;
} D3DHAL_DP2SETTEXLOD;

Members

dwDDSurface

Specifies a handle to a surface chain.

dwLOD

Controls the maximum MIP level loaded into video memory. Therefore, if the most detailed MIP map in the chain has dimensions 256x256, setting the maximum level to 2 means that the largest MIP map ever present in video memory has dimensions 64x64.

Remarks

Used only for driver-managed textures. This structure contains a surface handle to the MIP map and the maximum level of detail to set.

Requirements
