The ProbeSets service enables viewing of the probe sets in the scene. This service is only available if there are probe sets in the loaded scene.

When this service is selected (in the Rendering tab), the bounding box of the probe set and each individual probe within the set are rendered. The ProbeSets tab becomes available in the tab bar. Click this tab to display the edit options.

GeoRadiosity does not draw the outline of the volume box you put in. It draws the probes themselves, and draws the bounding box of those points. The probes are centred at the middle of each voxel, not at the corners. Therefore there is a half-voxel difference between the bounding box of the probes themselves, and the bounding box of the voxels.

Rendering options

Probe sets can be rendered in two ways:

Show as points	Point rendering is the fastest; points always render to at least a pixel regardless of the distance to the camera. Points can only be rendered with false colour shading where each probe set is rendered with a unique colour.
Show as spheres	Renders a small sphere centred at each probe position. Automatically scales the sphere, but the scale can be adjusted by using the Sphere scale slider. The spheres can be shaded using the controls listed below.
Show false colour	Renders each probe set with a unique colour.
Show radiosity	Shades the spheres with the radiosity of the probe.
Show visibility	Shades the probe with the visibility value calculated in the precompute translated to a greyscale colour; the colour's intensity is proportional to th visibility. Probe visibility is the proportion of valid (i.e. front-facing) geometry seen by the probe, where 0 means no valid geometry was seen and 1 means only valid geoetry was seen.
Show environment visibility	Shades the probe with the environment visibility calculated in the precompute translated to a greyscale colour with an intensity proportional to the visibility to the environment. This can be represented as either L0, L1 or L2 depending on the parameter set used for the probe set in question. L0 is a single intensity for the probe whereas L1 and L2 have some directional variation.
Show baked direct light visibility	Shades the probe with the baked binary visibility of the light currently selected in the ?Lighting tab, either white for visible or black for not. Requires that the light and probe set have been baked, and that the light has been baked with the generateLightMask attribute set to true. Unbaked probes and lights (including baked lights with generateLightMask set to false) will result in black probe sets.
Show precompute culling	The probes that were culled in the precompute are shown in red. Probes that were not culled are shown in green.
Sphere scale slider	Allows you to adjust the scale of the probes.
Cull probes interactively	Allows you to adjust the visibility threshold setting and preview which probes would be culled/not culled. Probes culled in this mode are simply not rendered.
Use compressed output	The ProbeSet calculation results can be stored in either full-width floats or an 8 byte compressed format. For most runtime environments the quality difference is marginal, but the memory difference can be significant; therefore it is recommended that you use the compressed output as the default.
