Member Function Documentation

◆ checkAndAdjustForNPoT()

void QSSGRhiContext::checkAndAdjustForNPoT	(	QRhiTexture *	texture,
		QSSGRhiSamplerDescription *	samplerDescription )

Adjusts samplerDescription's tiling and filtering modes based on the pixel size of texture.

In most cases, samplerDescription is not changed. With older, legacy 3D APIs in use, there is however a chance that tiling modes such as \l{QRhiSampler::Repeat} are not supported for textures with a non-power-of-two width or height.

This convenience function helps creating robust applications that can still function even when features such as \l{QRhi::NPOTTextureRepeat} are not supported by an OpenGL ES 2.0 or WebGL 1 implementation at run time.

Definition at line 1304 of file qssgrhicontext.cpp.

◆ commandBuffer()

QRhiCommandBuffer * QSSGRhiContext::commandBuffer ( ) const

Returns: The current frame's command buffer used by the Qt Quick 3D renderer.

Definition at line 1098 of file qssgrhicontext.cpp.

◆ commonPassFlags()

QRhiCommandBuffer::BeginPassFlags QSSGRhiContext::commonPassFlags ( ) const

Returns: The recommended flags when calling QRhiCommandBuffer::beginPass().

Definition at line 1719 of file qssgrhicontext.cpp.

◆ dummyTexture()

QRhiTexture * QSSGRhiContext::dummyTexture	(	QRhiTexture::Flags	flags,
		QRhiResourceUpdateBatch *	rub,
		const QSize &	size = QSize(64, 64),
		const QColor &	fillColor = Qt::black,
		int	arraySize = 0 )

Returns: a texture that has the specified flags and pixel size.

This is intended to efficiently gain access to a "dummy" texture filled with a given fillColor, and reused in various places in the rendering stack.

rub must be a valid QRhiResourceUpdateBatch since this function will create a new texture and generate content for it, if a suitable cached object is not found. The necessary upload operations are then enqueued on this given update batch.

When arraySize is 2 or more, a 2D texture array is returned.

The ownership of the returned texture stays with Qt Quick 3D.

Definition at line 1399 of file qssgrhicontext.cpp.

◆ isValid()

bool QSSGRhiContext::isValid ( ) const

Returns: true if the renderer is initialized successfully.

Definition at line 1069 of file qssgrhicontext.cpp.

◆ mainPassSampleCount()

int QSSGRhiContext::mainPassSampleCount ( ) const

Returns the sample count used in the main render pass.

Definition at line 1133 of file qssgrhicontext.cpp.

◆ mainPassViewCount()

int QSSGRhiContext::mainPassViewCount ( ) const

Returns the multiview count used in the main render pass.

This is either 2, when multiview rendering is in use, or 1 (no multiview).

Definition at line 1148 of file qssgrhicontext.cpp.

◆ mainRenderPassDescriptor()

QRhiRenderPassDescriptor * QSSGRhiContext::mainRenderPassDescriptor ( ) const

Returns: The QRhiRenderPassDescriptor used by the main render pass of the Qt Quick 3D renderer.

Definition at line 1084 of file qssgrhicontext.cpp.

◆ renderTarget()

QRhiRenderTarget * QSSGRhiContext::renderTarget ( ) const

Returns: The render target the Qt Quick 3D renderer uses for its main render pass in the current frame.

This can effectively be a render target from a swapchain, if the \l View3D uses a renderMode other than Offscreen. More commonly, the render target refers to a texture (i.e., is a QRhiTextureRenderTarget), e.g. because the renderMode is the default Offscreen, or because post-processing effects are in use.

Definition at line 1119 of file qssgrhicontext.cpp.

◆ rhi()

QRhi * QSSGRhiContext::rhi ( ) const

Returns: The QRhi object used by the Qt Quick 3D renderer.

Definition at line 1060 of file qssgrhicontext.cpp.

◆ sampler()

QRhiSampler * QSSGRhiContext::sampler ( const QSSGRhiSamplerDescription & samplerDescription )

Returns: a sampler with the filter and tiling modes specified in samplerDescription.

The generated QRhiSampler objects are cached and reused. Thus this is a convenient way to gain access to a QRhiSampler with the given settings, without having to create a new, dedicated object all the time.

The ownership of the returned QRhiSampler stays with Qt Quick 3D.
