Irradiance probes are used to render the irradiance at certain locations in the scene.
Rendering of irradiance probes is different from the usual rendering of buffers, like for example "result" or "normal". In particular, the orientation of the camera is irrelevant. Instead, locations of so-called irradiance probes are explicitly specified by this scene element which is attached to the camera (see mi::ICamera::set_irradiance_probes()).
To actually render the irradiance using these irradiance probes the render target needs to contain a canvas named "irradiance_probe" with pixel type "Rgb_fp". The product of the canvas resolution in x and y direction needs to match the number of irradiance probes. The irradiance probes are mapped to the canvas pixels in row-major order.
