QUniformValue *RenderView::inverseViewportMatrix(const QMatrix4x4 &model) const
{
    Q_UNUSED(model);
    QMatrix4x4 viewportMatrix;

}

Exemple #2

Fichier : renderview.cpp Projet : James-intern/Qt

QUniformValue *RenderView::viewportMatrix(const QMatrix4x4 &model) const
{
    // TODO: Can we avoid having to pass the model matrix in to these functions?
    Q_UNUSED(model);
    QMatrix4x4 viewportMatrix;
    viewportMatrix.viewport(resolveViewport(*m_viewport, m_surfaceSize));
    return QUniformValue::fromVariant(QVariant::fromValue(viewportMatrix), m_allocator);
