Light Object (Polar)

A physical light object using polar coordinates. Used with the Place Lights block.

Light Type: Light object type. "Point", "Area", or "Spot".

Coordinates: Coordinates of the light object relative to the bounding sphere of the target objects.

Radius: Radius of the polar coordinate, as a factor of the bounding sphere. For example, if the bounding sphere has a radius of 2 meters and the radius in this input is also set to 2, the light would be placed 4 meters from the origin.

Theta/Phi: Defines the azimuth angle and polar angle, respectively, expressed in degrees. Theta (azimuth) is limited to a range of [0, 360] and Phi (polar) is limited to a range of [0, 180]. [r=1, θ=0, φ=0]: Point at the upper pole of the sphere. [r=1, θ=0, φ=90]: Point at the equator, aligned to the +X world axis. [r=1, θ=90, φ=45]: Point aligned to the -Y world axis, halfway between the upper pole and equator. Size: "Size" of the light object. For Point and Spot lights, this is the radius of the light. For an Area light, this is the width/height of the light.

Power: Radiant power of the light in watts. Color Temp: Color temperature of the light in degrees Kelvin (more information on blackbody radiation may be found here).

Chance: Chance for this light to be created.
