## Inputs

### Ray Origin

Parameter ID: `RAYORIGIN` · Range: [XYZ ]

Defines the starting point of the raytracing in global coordinates. This normally reflects the position of the active render camera.

### Ray Direction

Parameter ID: `RAYDIRECTION` · Range: [XYZ ]

This is the direction vector of the rendered ray. This vector defines the direction from the Ray Origin in which the ray is underway.

### UVW

Parameter ID: `UVW` · Range: [XYZ ]

The UVW coordinates at the point on a surface currently being rendered.

### UVW Delta

Parameter ID: `UVWDELTA`

The radius measured in UVW coordinates that is used for calculating the RIP/MIP/SAT samples.

### Phong Normal

Parameter ID: `SHADINGNORMAL`

Defines the Normals at the object surface point currently being rendered.

### Time

Parameter ID: `TIME`

Defines the current animation time and can be used to control animated effects.
