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 includeHDRI Haven provides many CC0-licensed HDR images that can be used as source material for the above tools.
- class PySide2.Qt3DRender.Qt3DRender.QEnvironmentLight([parent=None])¶
- Parameters:
parent –
PySide2.Qt3DCore.Qt3DCore.QNode
- PySide2.Qt3DRender.Qt3DRender.QEnvironmentLight.irradiance()¶
- Return type:
Holds the current environment irradiance map texture.
By default, the environment irradiance texture is null.

- Parameters:
irradiance –
PySide2.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.
- PySide2.Qt3DRender.Qt3DRender.QEnvironmentLight.setSpecular(specular)¶
