Best way to "draw" dynamically a 3D house shape using QML.

efdiloreto

I want to draw different types of structures and allow the user to change there's dimensions from the 3D view.

For example giving the following image, clicking in the width dimension will update the shape:

alt text

This is possible to make with QML?

I think you should define a unique entity for your house, containing sub entities of the differents surfaces and properties binded to your surfaces dimmensions. To manage those properties you could then use some methods that you could call from other entities when they are clicked (like the arrow of your picture).

This should look approximately like that (to me) :

Entity
            {
                id: house

                property real height     // Total height of your house
                property real length     // Total length of your house
                property real width      // Total width of your house

                Entity
                {
                    id: surface1

                    ObjectPicker
                    {
                        id: surface1Picker
                        hoverEnabled: true
                        onEntered:
                        {
                            // Your code here
                        }
                        onExited:
                        {
                            // Your code here
                        }
                        onClicked:
                        {
                            // Your code here
                        }
                    }

                    PlaneMesh
                    {
                        id: surface1Mesh
                        width: // Dimmensions according to properties
                        height: // Dimmensions according to properties
                        meshResolution: Qt.size(2, 2)
                    }

                    Texture2D
                    {
                        id: surface1Texture
                        TextureImage
                        {
                             id: texture1Image
                             source : ""
                             mirrored: false
                        }
                    }

                    DiffuseMapMaterial
                    {
                        id: surface1Material
                        diffuse: surface1Texture
                        shininess: 0
                    }

                    Transform
                    {
                        id: surface1Transform
                        scale3D: Qt.vector3d(1, 1, 1)
                        rotation: fromAxisAndAngle(Qt.vector3d(1, 0, 0), 90)
                        translation: Qt.vector3d(x, y, z)  // x, y and z are set according to your properties
                    }

                    components: [ surface1Mesh, surface1Material, surface1Transform, surface1Picker ]
                }

                Entity
                { ...}
        }

Thanks! I'll try it.
