详细描述

Encapsulate an environment light object in a Qt 3D scene.

QEnvironmentLight uses cubemaps to implement image-based lighting (IBL), a technique often used in conjunction with physically-based rendering (PBR). The cubemaps are typically expected be based on high dynamic range (HDR) images, with a suitable OpenGL format (such as RGBA16F) that can handle the increased range of values.

There are a variety of tools that can be used to produce the cubemaps needed by QEnvironmentLight . Some examples include

• cmftStudio
• IBLBaker
• Lys

HDRI Haven provides many CC0-licensed HDR images that can be used as source material for the above tools.

irradiance : Qt3DRender::QAbstractTexture *

Holds the current environment irradiance map texture.

By default, the environment irradiance texture is null.

访问函数：

Qt3DRender::QAbstractTexture *	irradiance () const
void	setIrradiance (Qt3DRender::QAbstractTexture * irradiance )

通知程序信号：

void	irradianceChanged (Qt3DRender::QAbstractTexture * environmentIrradiance )

specular : Qt3DRender::QAbstractTexture *

Holds the current environment specular map texture.

By default, the environment specular texture is null.

访问函数：

Qt3DRender::QAbstractTexture *	specular () const
void	setSpecular (Qt3DRender::QAbstractTexture * specular )

通知程序信号：

void	specularChanged (Qt3DRender::QAbstractTexture * environmentSpecular )

成员函数文档编制

QEnvironmentLight:: QEnvironmentLight ( Qt3DCore::QNode * parent = nullptr)

Default constructs an instance of QEnvironmentLight.

[虚拟] QEnvironmentLight:: ~QEnvironmentLight ()

Destroys the instance of QEnvironmentLight. The destructor is virtual.
