Field Operators

Float or vector fields, which provide values for the requested coordinates.

They can be used to control the behavior of other OPs, such as rotating by different amounts in different positions, or pulling color values from a texture.

Operators

• atmosphereField : Field that simulates a sun and sky.
• axisDistanceField : A float field that provides the distance from a specific point along a single axis.
• bandField : Field that applies values based on a band/slice of an axis.
• blackbodyColorField :
• cellTileField : A value field that provides an approximation of repeating cellular (voronoi) noise.
• chopField : Field that provides values from a CHOP.
• colorRampField : A vector field that maps an input field to values from a range of colors.
• colorSwitchField : Switches or fades between a list of colors based on an index field.
• constantColorField : A vector field that evaluates to a constant color value.
• constantField : A float or vector field that evaluates to a constant value.
• constantSwitchField : Switches or blends between constant values based on an index field.
• curlNoiseField : Curl noise field.
• dataTextureField : Accesses data from a texture with the same layout as the renderer.
• domainColorField : beta
• hashField : beta
• hsvColorField : A field that uses HSV-based parameters to produce colors.
• iterationField : Field that returns the current iteration, from a downstream OP.
• magnetField : beta
• metaballField : Metaball value field.
• multiPointDistanceField : A vector field that provides the distance from 4 specific points in space (one for each part of the vector).
• nearestRingPointField :
• noiseField : A float or vector field that uses one of several noise functions.
• normalField : deprecated Vector field that produces the surface normal where it is evaluated.
• pointDistanceField : A float field that provides the distance from a specific point in space from either the current position or from another point.

• reorderField :
• sdfField : Value field based on an SDF shape.
• sdfNormalField : beta
• spectralColorField :
• stepField : A field that switches between two values at a threshold point.
• terrainNoiseField : beta
• texture1dField : beta
• texture3dField :
• textureField : A float or vector field that looks up values from a texture.
• triPlanarTextureField : Texture field that uses surface normals (or other blending techniques) to apply a texture facing each axis.
• uvField : Field that produces surface UV coordinates, if available.
• waveField : A field that uses a periodic wave.
• waveVectorField : beta
• waveletNoiseField :
• worleyNoiseField :
