Scene3D QML 类型

Scene3D 类型用于将 Qt3D 场景集成到 QtQuick 2 场景中。 更多...

此类型正在开发中，并可能会发生变化。

• 包括继承成员在内的所有成员列表

属性

• aspects : list<string>
• cameraAspectRatioMode : enumeration
• compositingMode : enumeration
• entity : Entity
• hoverEnabled : bool
• multisample : bool

方法

• void setItemAreaAndDevicePixelRatio(size area, real devicePixelRatio)

详细描述

The Scene3D type renders a Qt3D scene, provided by an Entity, into a multisampled Framebuffer object. This object is later blitted into a non-multisampled Framebuffer object, which is then rendered with premultiplied alpha. If multisampling is not required, it can be avoided by setting the multisample property to false. In this case Scene3D will render directly into the non-multisampled Framebuffer object.

If the scene to be rendered includes non-opaque materials, you may need to modify those materials with custom blend arguments in order for them to be rendered correctly. For example, if working with a PhongAlphaMaterial and a scene with an opaque clear color, you will likely want to add

sourceAlphaArg: BlendEquationArguments.Zero
destinationAlphaArg: BlendEquationArguments.One

到那个材料中。

不推荐在一个应用程序中创建多个 Scene3D 实例。原因是 Scene3D 实例在场景下方实例化了整个 Qt 3D 引擎（内存管理器、线程池、渲染等）。
