Member Function Documentation

◆ create()

bool QD3D11Texture::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.

Implements QRhiTexture.

References finishCreate(), and owns.

Here is the call graph for this function:

◆ createFrom()

bool QD3D11Texture::createFrom ( QRhiTexture::NativeTexture src )

overridevirtual

Similar to create(), except that no new native textures are created.

Instead, the native texture resources specified by src is used.

This allows importing an existing native texture object (which must belong to the same device or sharing context, depending on the graphics API) from an external graphics engine.

Returns: true if the specified existing native texture object has been successfully wrapped as a non-owning QRhiTexture.

Note: format(), pixelSize(), sampleCount(), and flags() must still be set correctly. Passing incorrect sizes and other values to QRhi::newTexture() and then following it with a createFrom() expecting that the native texture object alone is sufficient to deduce such values is wrong and will lead to problems.; QRhiTexture does not take ownership of the texture object. destroy() does not free the object or any associated memory.

The opposite of this operation, exposing a QRhiTexture-created native texture object to a foreign engine, is possible via nativeTexture().

Note: When importing a 3D texture, or a texture array object, or, with OpenGL ES, an external texture, it is then especially important to set the corresponding flags (ThreeDimensional, TextureArray, ExternalOES) via setFlags() before calling this function.

Reimplemented from QRhiTexture.

References finishCreate(), and owns.

Here is the call graph for this function:

◆ destroy()

void QD3D11Texture::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.

Note: Resources referenced by commands for the current frame should not be released until the frame is submitted by QRhi::endFrame().

The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.

Here is the caller graph for this function:
