D2D1_VERTEX_USAGE enumeration

Indicates whether the vertex buffer changes infrequently or frequently.

Syntax


typedef enum D2D1_VERTEX_USAGE { 
  D2D1_VERTEX_USAGE_STATIC   = 0,
  D2D1_VERTEX_USAGE_DYNAMIC  = 1
} D2D1_VERTEX_USAGE;

Constants

D2D1_VERTEX_USAGE_STATIC

The created vertex buffer is updated infrequently.

D2D1_VERTEX_USAGE_DYNAMIC

The created vertex buffer is changed frequently.

Remarks

If a dynamic vertex buffer is created, Direct2D will not necessarily map the buffer directly to a Direct3D vertex buffer. Instead, a system memory copy can be copied to the rendering engine vertex buffer as the effects are rendered.
