qml qt3d documentation

[tanshihaj]

Is there any documentation to qt3d module? 5.6rc documentation isn't complete enough.

The question is about materials. I'm trying to change color of entity like that:

Material {
    id: material
    effect: Effect { }
    parameters: [
        Parameter { name: "ambient";   value: Qt.vector3d(0.0, 1.0, 0.0) },
        Parameter { name: "diffuse";   value: Qt.vector3d(0.0, 1.0, 0.0) },
        Parameter { name: "specular";  value: Qt.vector3d(0.0, 1.0, 0.0) },
        Parameter { name: "shininess"; value: 150.0 }
    ]
 }

But the color is still standard orange. The full qml file:

        property real old_y : 0
        onPressed: {
            old_x = mouse.x;
            old_y = mouse.y;
        }
        onPositionChanged: {
            var delta_x = mouse.x - old_x;
            var delta_y = mouse.y - old_y;

Hi,

The module being in tech preview, currently the best place to ask Qt3D related question is the interest mailing list. You'll find there Qt3D's developers/maintainers (this forum is more user oriented)
