The '''Sphere For Tangent Line''' node takes a line point for our sphere point, a line in 3D space, and point for the line, creating a sphere in 3D space. Then it returns the point and radius of a sphere, similar to a reversed [[ProtoFlux:Tan|Tan]] node.

== Inputs ==

=== LinePoint ([[Type:float3|float3]]) === 

The point where the line is.

=== LineDirection ([[Type:float3|float3]]) ===

The direction of a line provided.

=== SphereCenter ([[Type:float3|float3]]) ===

The sphere point we want to make (in some distance away from the line).

== Outputs ==

=== TangentPoint ([[Type:float3|float3]]) ===

Returns the tangent point where the line and sphere touch.

=== Radius ([[Type:float|float]]) ===

Returns the radius of the sphere that is created by this calculation.
