Public Member Functions
virtual void	QueryInterface (const Diligent::INTERFACE_ID &IID, IObject **ppInterface)=0
	Queries the specific interface, see IObject::QueryInterface() for details.
virtual const TextureViewDesc &	GetDesc () const =0
	Returns the texture view description used to create the object.
virtual void	SetSampler (class ISampler *pSampler)=0
	Sets the texture sampler to use for filtering operations when accessing a texture from shaders. Only shader resource views can be assigned a sampler. The view will keep strong reference to the sampler.

	Decrements the number of strong references by 1 and destroys the object when the counter reaches zero. More...
virtual IReferenceCounters *	GetReferenceCounters () const =0
	Returns the pointer to IReferenceCounters interface of the associated reference counters object. The metod does NOT increment the number of strong references to the returned object.

Detailed Description

Texture view interface.

Remarks

To create a texture view, call ITexture::CreateView(). Texture view holds strong references to the texture. The texture will not be destroyed until all views are released. The texture view will also keep a strong reference to the texture sampler, if any is set.

Member Function Documentation

virtual void Diligent::ITextureView::GenerateMips ( IDeviceContext *  pContext )

pure virtual

Generates a mipmap chain.

Remarks

This function can only be called for a shader resource view The texture must be created with MISC_TEXTURE_FLAG_GENERATE_MIPS flag

Implemented in Diligent::TextureViewD3D11Impl, Diligent::TextureViewGLImpl, and Diligent::TextureViewD3D12Impl.

virtual ISampler* Diligent::ITextureView::GetSampler ( )

pure virtual

Returns the pointer to the sampler object set by the ITextureView::SetSampler().

The method does NOT call AddRef() on the returned interface, so Release() must not be called.

Implemented in Diligent::TextureViewBase< ITextureViewD3D12, FixedBlockMemoryAllocator >, Diligent::TextureViewBase< ITextureViewGL, FixedBlockMemoryAllocator >, and Diligent::TextureViewBase< ITextureViewD3D11, FixedBlockMemoryAllocator >.

virtual class ITexture* Diligent::ITextureView::GetTexture ( )

pure virtual

Returns the pointer to the referenced texture object.

The method does NOT call AddRef() on the returned interface, so Release() must not be called.

Implemented in Diligent::TextureViewBase< ITextureViewD3D12, FixedBlockMemoryAllocator >, Diligent::TextureViewBase< ITextureViewGL, FixedBlockMemoryAllocator >, and Diligent::TextureViewBase< ITextureViewD3D11, FixedBlockMemoryAllocator >.
