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.
