This is the position of the currently rendered position on the surface in the global coordinates.
This is the standardized direction from which the render sample hits the point currently being rendered.
This is the global start position of the render sample currently being calculated. This is, as a rule, identical to the position of the active render camera.
This is the Normal direction prior to adding Normal mapping.
This is the final Normal direction at the point currently being rendered as is defined after the Normal Map, Phong tag or Normal tag has been evaluated.
Here you will find the original Normal direction as is defined by the polygon’s position.
The calculation of the surface Normals is based on the point of intersection between two edge directions of a polygon. This calculation is, however, not enough to get a smoothed Normal because the surrounding polygons must be included in the calculation. For this purpose, curves will be generated that run in the U and V directions. Tangents can be generated along these curves that will produce smoothed Normals at every location on the surface. The Tangent output displays the tangent in the U direction.
This tangent represents the tangent in the V direction.
These are the unmodified UVW coordinates of the surface at the point currently being rendered.
These are the UVW coordinates – possibly modified via the Context input – at the point currently being rendered.
The Barycentric coordinates define an alternative coordinate system that spans a polygon’s plane. This axis’ origin lies at the Center of the respective triangle or quad. Positions within the polygon can then be defined based on their distance from the surface’s (limiting) edges. The position of the rendered point relative to the center point of the respective polygon will be defined.
Here the coordinates of the currently rendered pixel will be output.
For sampling, multiple render rays have to be emitted to different locations within a pixel. Sub-Pixel defines the position of the sub-pixel currently being rendered.
These coordinates output the position of each surface point relative to the image coordinates. The image coordinate system has its origin at the top left corner.
Outputs the render resolution currently being used from the active Render Settings.
