Qt 3D：簡單 QML 範例

QML 應用程序演示如何在 Qt 3D 中渲染場景。

簡單演示如何在 Qt 3D 渲染場景。

運行範例

要運行範例從 Qt Creator ，打開歡迎模式，然後選擇範例從範例。更多信息，拜訪構建和運行範例 .

設置場景

我們設置整個場景在 main.qml 文件。

To be able to use the types in the Q3D and Q3D Render modules, we must import the modules:

import Qt3D.Core 2.0
import Qt3D.Render 2.0

創建第 1 個實體 Camera , which represents the camera used for the final rendering, and a camera controller, which allows us to control this camera using the keyboard or the mouse:

    Camera {
        id: camera
        projectionType: CameraLens.PerspectiveProjection
        fieldOfView: 45
        aspectRatio: 16/9
        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 )
    }
    OrbitCameraController {
        camera: camera
    }

A RenderSettings entity specifies a ForwardRenderer as the active framegraph:

    components: [
        RenderSettings {
            activeFrameGraph: ForwardRenderer {
                clearColor: Qt.rgba(0, 0.5, 1, 1)
                camera: camera
                showDebugOverlay: true
            }
        },

The event source is set by the Qt3DQuickWindow:

        InputSettings { }
