D2D1_RESOURCE_TYPE enumeration

  • Artículo

Specifies which kinds of resources should be released when ID2D1Device::ClearResources is invoked.

Syntax

typedef enum  { 
  D2D1_RESOURCE_TYPE_NONE    = 0,
  D2D1_RESOURCE_TYPE_SHADER  = 1,
  D2D1_RESOURCE_TYPE_BUFFER  = 2
} D2D1_RESOURCE_TYPE;

Constants

  • D2D1_RESOURCE_TYPE_NONE
    No resources will be cleared.

  • D2D1_RESOURCE_TYPE_SHADER
    Any unreferenced shader resources will be released.

  • D2D1_RESOURCE_TYPE_BUFFER
    Any unreferenced buffer resources will be released.

Remarks

The buffer resource type includes cached vertex buffers or textures.

Pixel shaders are comparatively small and take considerable resources to compile. The application should be conservative in discarding these resources. Maintaining references to effects that the application will use in the future will often prevent these shaders from being discarded.
