Qt 3D: Scene3D QML Example

A QML application that demonstrates visualizing a 3D scene.

This example demonstrates visualizing a 3D scene from a Qt Quick application. The 3D scene contains a single active camera and a single active light source. Visualized data is assumed to be at a fixed location.

Running the Example

To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.

Visualizing 3D Scenes

We set up the 3D scene and specify the entity to animate in main.qml:

          Scene3D {
              id: scene3d
              anchors.fill: parent
              anchors.margins: 10
              focus: true
              aspects: ["input", "logic"]
              cameraAspectRatioMode: Scene3D.AutomaticAspectRatio

              AnimatedEntity {}
          }

We specify the active camera in scene3d/AnimatedEntity.qml:

      Camera {
          id: camera
          projectionType: CameraLens.PerspectiveProjection
          fieldOfView: 45
          nearPlane : 0.1
          farPlane : 1000.0
          position: Qt.vector3d( 0.0, 0.0, 40.0 )
          upVector: Qt.vector3d( 0.0, 1.0, 0.0 )
          viewCenter: Qt.vector3d( 0.0, 0.0, 0.0 )
      }
