PySide6.QtGui.QRhiVertexInputLayout¶

class QRhiVertexInputLayout¶

Describes the layout of vertex inputs consumed by a vertex shader.

Details

The vertex input layout is defined by the collections of QRhiVertexInputBinding and QRhiVertexInputAttribute .

As an example, let’s assume that we have a single buffer with 3 component vertex positions and 2 component UV coordinates interleaved (x, y, z, u, v), that the position and UV are expected at input locations 0 and 1 by the vertex shader, and that the vertex buffer will be bound at binding point 0 using setVertexInput() later on:

QRhiVertexInputLayout inputLayout;
inputLayout.setBindings({
    { 5 * sizeof(float) }
});
inputLayout.setAttributes({
    { 0, 0, QRhiVertexInputAttribute::Float3, 0 },
    { 0, 1, QRhiVertexInputAttribute::Float2, 3 * sizeof(float) }
});

Note

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

Added in version 6.6.
