The Sample Color outputs the visible color sampled in a line along the input Direction vector from the input Origin when an impulse is received at Sample.

Usage

The color is sampled after applying all effects of lighting, shadows, emissives, alpha blending of materials etc. along the sampling direction.

The Reference input is the slot in whose local coordinate space the Origin and Direction vectors are interpreted. This is the root slot by default, meaning the global coordinate space is used.

The NearClip input sets a lower bound on the distance at which objects will be included in the sampling. Anything closer to the input Origin than the NearClip value will be ignored.

The FarClip input sets an upper bound on the distance at which objects will be included in the sampling. Anything further from the input Origin than the FarClip value will be ignored.

The OnSampleStart output fires an impulse when the sampling operation begins. This is the impulse passthrough output for the Sample input. Note that the Color output will not yet have the sampled color value!

The OnSampled output fires an impulse when the sampling operation completes. The sampled color will be available from the Color output for the duration of the impulse chain stared by OnSampled. Note that other transient values available during the impulse chain which arrives at Sample and continues from OnSampleStart may not be available during the impulse chain initiated from OnSampled.
