PySide6.QtGui.QRhiViewport¶

class QRhiViewport¶

Specifies a viewport rectangle.

Details

Used with setViewport() .

QRhi assumes OpenGL-style viewport coordinates, meaning x and y are bottom-left. Negative width or height are not allowed.

Typical usage is like the following:

const QSize outputSizeInPixels = swapchain->currentPixelSize();
const QRhiViewport viewport(0, 0, outputSizeInPixels.width(), outputSizeInPixels.height());
cb->beginPass(swapchain->currentFrameRenderTarget(), Qt::black, { 1.0f, 0 });
cb->setGraphicsPipeline(ps);
cb->setViewport(viewport);
// ...

Note

This is a RHI API with limited compatibility guarantees, see QRhi for details.

__init__()¶

Constructs a viewport description with an empty rectangle and a depth range of 0.0f - 1.0f.

clipSpaceCorrMatrix()

__init__(x, y, w, h[, minDepth=0.0f[, maxDepth=1.0f]])

Parameters:

x – float
y – float
w – float
h – float
minDepth – float
maxDepth – float

Constructs a viewport description with the rectangle specified by x, y, w, h and the depth range minDepth and maxDepth.

Note

x and y are assumed to be the bottom-left position. w and h should not be negative, the viewport will be ignored by setViewport() otherwise.
