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

cmftStudio

IBLBaker

Lys

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

class PySide6.Qt3DRender.Qt3DRender.QEnvironmentLight([parent=None])#

Parameters:: parent – PySide6.Qt3DCore.Qt3DCore.QNode

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.Qt3DRender.Qt3DRender.QEnvironmentLight.irradiance: PySide6.Qt3DRender.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:

irradiance ()
setIrradiance (irradiance)
Signal irradianceChanged (environmentIrradiance)

property PᅟySide6.Qt3DRender.Qt3DRender.QEnvironmentLight.specular: PySide6.Qt3DRender.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:

specular ()
setSpecular (specular)
Signal specularChanged (environmentSpecular)
