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	Field that produces colors using a model of blackbody radiation from physics.
	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	Advanced field that produces randomized values.
	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.
	polarCoordField	A field that produces various types of polar coordinates.
	polarVectorField
	positionField	A vector field that produces the coordinates in space where it is checked.
	rampField beta	Field that produces values that fade from one value to another along an axis or line.
	rayField	Field that provides the ray direction or origin.
	reorderField
	sdfField	Value field based on an SDF shape.
	sdfNormalField beta
	spectralColorField	Produces colors using rainbow spectrum patterns.
	stepField	A field that switches between two values at a threshold point.
	terrainNoiseField beta	Noise that uses fBm (fractal brownian motion), which can work well for surface offsetting for terrain.
	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.

	waveField	A field that uses a periodic wave.
	waveVectorField beta
	waveletNoiseField
	worleyNoiseField
