Filter Operators

Operators that take an input and modify it.

Many of these are spatial transformations (scale, rotate, translate), which alter the coordinates that are used by their input operator.

Many of these can be used for various types of return types (SDFs, float/vector fields, etc). Some only support a limited set of return types.

Operators

	adjustColor	Adjust properties of color values, either directly on a field, or on the assigned surface color of an Sdf result.
	applyTransform beta
	assignAttribute beta
	assignColor	Assigns a surface color attribute to an SDF surface.
	assignUV	Assigns UV coordinates to an SDF surface.
	axisRotate	A simplified and optimized version of `rotate`, which only supports rotating around a single axis (x, y, or z).
	bend	Bends space, along a main axis, towards a second axis.
	cameraTransform beta	Specialized transform that can be applied to cameras.
	cartesianToPolar	Convert from cartesian space to various types of polar spaces.
	circularRepeat beta	Repeat an space to fill a 2D circular area.
	elongate	Stretches a shape by splitting it into pieces, moves them apart, and connects them.
	extend	Clamps coordinates around an area, which causes its edges to be extended infinitely along each axis.
	fieldExpr beta	Modifies field values using a custom expression.
	fieldFunction	Modifies the values of a field using various types of math functions, similar to a `Function CHOP`.
	flip	Flips the input across an axis, either on its own or merged with the original.
	fold
	geometricSeriesSquareTile beta	Repeats space in a square arrangement that gets smaller in the center.
	gridClone	Repeats an SDF in a grid arrangement, combining the results.
	hilbertCurveTransform beta
	instance	Repeats its input some number of times, exposing the index as the iteration x value, and combines the results.
	instanceField	Repeats an input field multiple times and combines the results.
	invert	Invert an SDF, so that the inside is the outside.
	iteratedTransform	Performs a transform multiple times, optionally reflecting across axes in between the steps.
	kink	Bends space, similar to the `bend`.
	knife	Cuts off an SDF along a plane.
	lightTransform beta	Specialized transform that can be applied to lights, taking into account things like look at direction.
	limitArea beta	Use an SDF to limit the area where a field produces values.
	limitField	Limits the values produced by a float or vector field.
	limitLight beta	Limits the brightness of a light using distance attenuation or a bounding SDF (or both).
	linearClone	Repeats an SDF along a line, combining the results.
	logPolarRepeat beta
	lookAtRotate beta	Rotates space to face towards a point.
	magnet	Pulls or twists space within an area.
	mirrorAxes	Mirror space across one or more axes, similar to `reflect`.
	mirrorOctant	Mirror coordinates across two axes and the diagonals.
	mirrorQuadrant	Mirror coordinates across two axes.
	mobiusTransform
	modifyDistance beta
	modifyNormals	Use a field to modify the normals (bump mapping) used by shading elements in a modular material.
	modulo1D	Repeats space along one axis.
	modulo2D	Repeats space along 2 axes.
	modulo3D	Repeats space along all 3 axes.
	moduloDistance
	moduloLine beta	Repeats space along a line, similar to `modulo1D`.
	moduloPolar	Repeats space radially, like a kaleidoscope.
	moduloSpherical	Repeats space in a spherical mesh layout with rows and columns.
	moduloToroidal beta	Repeats space as rows and columns of a torus-shaped grid.
	onion	Converts a solid SDF to a thin shell of the surface.
	polarToCartesian beta	Converts coordinates from polar to cartesian.
	quadTreeRepeat beta	Repeats space in a 2d grid where some cells are subdivided into smaller cells recursively.
	quantizeCoords	Quantize coordinates to a 3D grid, which is sort of like "voxelizing" the space.
	quantizeValue
	radialClone	Repeats an SDF radially around an axis, combining the resulting shapes.
	radialSlice	Takes a pie-shaped slice of an SDF around an axis, either removing it or everything except it.
	rangeTransform	Applies a transform based on a range of settings, mapped with either the iteration value or a field input.
	rectangleRepeat beta
	reflect	Reflects space across a plane.
	remapCoords beta	Modifies space using a vector field.
	reorderCoords	Swaps axes for the input.
	rescaleField	Rescales the values produced by a field.
	rescaleFloatField	Simplified version of `rescaleField` that only has single settings vs vectors for each.
	reshapeValues	Reshapes the values produced by a field by applying a function.
	restrictStage	Restricts which render stages an operator is used in.
	rotate	Transforms space with rotation.
	rotate4D	Projects 3D space into 4D space, applies rotation along two axes and then projects back into 3D space.
	rotateNormals	Applies rotation to the surface normals used by material elements such as `specularContrib`.
	round	Adds to (or subtracts from) the size of an SDF, which has the effect of rounding it out or shrinking it.
