Camera Rotation around a mesh

[Naveen_D]

Hi all,
I am using 3D in qml and trying a simple example of torusmesh. What i am doing is, i have an entity within which i have camera, material, transform and torus mesh, what i want to do is, to fix the camera and move the mesh and all x,y,z direction (i want to rotate the mesh in 360deg) i am trying with the following code but that is not happening. can anyone guide me through this ?
Thank you
here is the code :

import QtQuick 2.2
import Qt3D.Core 2.0
import Qt3D.Render 2.0
import Qt3D.Input 2.0
import Qt3D.Extras 2.0

Entity {
    id: sceneRoot

    Camera {
        id: camera
        projectionType: CameraLens.PerspectiveProjection
        fieldOfView: 45
        aspectRatio: 16/9
        nearPlane : 0.1
        farPlane : 1000.0
        position: Qt.vector3d( 0, 0.0, 20.0 )
        upVector: Qt.vector3d( 0.0, 1.0, 0.0 )
        viewCenter: torusTransform.translation
    }

//    OrbitCameraController {camera: camera}
    FirstPersonCameraController { camera: camera}

    components: [
        RenderSettings {
            activeFrameGraph: ForwardRenderer {
                clearColor: Qt.rgba(0, 0.5, 1, 1)
                camera: camera
            }
        },
        // Event Source will be set by the Qt3DQuickWindow
        InputSettings { }
    ]

    PhongMaterial {
        id: material
    }

    TorusMesh {
        id: torusMesh
        radius: 5
        minorRadius: 1
        rings: 100
        slices: 20        
    }

    Transform {
        id: torusTransform
        scale3D: Qt.vector3d(1.5, 1, 0.5)
        rotation: fromAxisAndAngle(Qt.vector3d(1, 0, 0), 45)
        translation: Qt.vector3d(0,0,0)
    }

    Entity {
        id: torusEntity

        components: [ torusMesh, material, torusTransform ]
    }

}

@Naveen_D said in Camera Rotation around a mesh:

(i want to rotate the mesh in 360deg)

Transform {
    id: transf
    NumberAnimation on rotationY { 
        to: 360
        duration: 1000
        running: true  
    }
}

@Wieland Thank you for the reply,

I got the output, but another thing is i want to rotate it using the mouse cursor, is it possible ?
I want to rotate the car like this,

Dodge Viper

Thank you

@Naveen_D I don't know how to do this. There is very little documentation for Qt3D. You need to study the sources: http://code.qt.io/cgit/qt/qt3d.git/tree/src
