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 Welcome 模式，然後選擇範例從 Examples 。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 )
}

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
        }
    },
    // Event Source will be set by the Qt3DQuickWindow
    InputSettings { }
]

The event source is set by the Qt3DQuickWindow:

InputSettings { }
