structure CD3D11_SAMPLER_DESC (d3d11.h)

Représente un état d’échantillonneur et fournit des méthodes pratiques pour créer des états de l’échantillonneur.

Syntax

struct CD3D11_SAMPLER_DESC : D3D11_SAMPLER_DESC {
  void CD3D11_SAMPLER_DESC();
  void CD3D11_SAMPLER_DESC(
    const D3D11_SAMPLER_DESC & o
  );
  void CD3D11_SAMPLER_DESC(
    CD3D11_DEFAULT unnamedParam1
  );
  void CD3D11_SAMPLER_DESC(
    D3D11_FILTER               filter,
    D3D11_TEXTURE_ADDRESS_MODE addressU,
    D3D11_TEXTURE_ADDRESS_MODE addressV,
