Class QAccelPlot::DataTexture

ClassList > QAccelPlot > DataTexture

Series data uploaded to the GPU as an RGBA8888 texture, one float per texel. More...

• #include <DataTexture.hpp>

Public Functions

Type	Name
	DataTexture () = default Constructs an empty data texture; texture() staysnullptr until the first upload.
	DataTexture (std::unique_ptr< QSGTexture > texture) Wraps the existing texture , for example in tests.
QSGTexture *	texture () const Returns the texture the shaders sample, or nullptr before the first successful upload.
void	upload (QQuickWindow * window, const float * data, int floatCount) Uploads floatCount raw floats from__data , reusing GPU and CPU buffers where possible.

Detailed Description

Materials hold it through a std::shared_ptr, so several nodes of one series can sample the same upload. It is created and destroyed on the render thread, like the materials holding it.

function upload

Uploads floatCount raw floats from__data , reusing GPU and CPU buffers where possible.

void QAccelPlot::DataTexture::upload (
    QQuickWindow * window,
    const float * data,
    int floatCount
) 

Does nothing when window is nullptr or floatCount is not positive.
