Member Function Documentation

◆ create()

bool QD3D11GraphicsPipeline::create ( )

overridevirtual

Creates the corresponding native graphics resources.

If there are already resources present due to an earlier create() with no corresponding destroy(), then destroy() is called implicitly first.

Returns: true when successful, false when a graphics operation failed. Regardless of the return value, calling destroy() is always safe.

Note: This may be, depending on the underlying graphics API, an expensive operation, especially when shaders get compiled/optimized from source or from an intermediate bytecode format to the GPU's own instruction set. Where applicable, the QRhi backend automatically sets up the relevant non-persistent facilities to accelerate this, for example the Vulkan backend automatically creates a VkPipelineCache to improve data reuse during the lifetime of the application.; Drivers may also employ various persistent (disk-based) caching strategies for shader and pipeline data, which is hidden to and is outside of Qt's control. In some cases, depending on the graphics API and the QRhi backend, there are facilities within QRhi for manually managing such a cache, allowing the retrieval of a serializable blob that can then be reloaded in the future runs of the application to ensure faster pipeline creation times. See QRhi::pipelineCacheData() and QRhi::setPipelineCacheData() for details. Note also that when working with a QRhi instance managed by a higher level Qt framework, such as Qt Quick, it is possible that such disk-based caching is taken care of automatically, for example QQuickWindow uses a disk-based pipeline cache by default (which comes in addition to any driver-level caching).

Implements QRhiGraphicsPipeline.

Here is the call graph for this function:

◆ destroy()

void QD3D11GraphicsPipeline::destroy ( )

overridevirtual

Releases (or requests deferred releasing of) the underlying native graphics resources.

Safe to call multiple times, subsequent invocations will be a no-op then.

Once destroy() is called, the QRhiResource instance can be reused, by calling create() again. That will then result in creating new native graphics resources underneath.
