fromScene method

RenderTarget fromScene(Scene scene, { double sigma = 0, double near = 0.1, double far = 100, PMREMGeneratorOptions? options, })

• Generates a PMREM from a supplied Scene, which can be faster than using an
• image if networking bandwidth is low. Optional sigma specifies a blur radius
• in radians to be applied to the scene before PMREM generation. Optional near
• and far planes ensure the scene is rendered in its entirety (the cubeCamera
• is placed at the origin).
