Detailed Description

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

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

Property Documentation

irradiance : Qt3DRender::QAbstractTexture*

Holds the current environment irradiance map texture.

By default, the environment irradiance texture is null.

Note: The exact meaning and use of this property is up to the material implementation.

Access functions:

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

Notifier signal:

void	irradianceChanged(Qt3DRender::QAbstractTexture *environmentIrradiance)

specular : Qt3DRender::QAbstractTexture*

Holds the current environment specular map texture.

By default, the environment specular texture is null.

Note: The exact meaning and use of this property is up to the material implementation.

Access functions:

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

Notifier signal:

void	specularChanged(Qt3DRender::QAbstractTexture *environmentSpecular)
