Qt 3D：简单 QML 范例

QML 应用程序演示如何在 Qt 3D 中渲染场景。

Simple 演示如何在 Qt 3D 渲染场景。

运行范例

要运行范例从 Qt Creator ，打开 Welcome 模式，然后选择范例从 Examples 。更多信息，拜访 构建和运行范例 .

设置场景

我们设置整个场景在 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
					

创建第一个实体 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 { }
