Houdini Facing Ratio v1.0 HDA

Calculates the cosine of the angle between an incident vector and the point or vertex normals of a mesh and outputs the result as a -1 to +1 float point attribute. (By default, the toggle to fit that range from 0 to 1 is on.)

Two modes of operation:

- Camera (calculate with respect to a scene camera)

- Direction (specify a direction vector and world or object space)

For convenience:

- A spline ramp

- Camera operator chooser with camera object filter

Nice extras:

- Trace what's in direct line of sight and output 'povmask' point attribute.

- Optional input 2 for geometry blocking the line of sight to be accounted for in 'povmask'.

- Useful when you want to have an attribute available further downstream to mask stuff invisible to the camera for example.

Wohoo! More attribs and procedurals! Yes!
