v0.24
Highlights
Parameter optimization. For many parameters, if they’re marked as read-only, RayTK will bake them into the shader.
This significantly improves performance, but means that if they change the shader has to recompile.
The new sceneState component helps with switching scenes between a “locked” optimized state and an “unlocked” editing state.
Changes to variable type handling may cause compatibility issues for variableReference operators. To fix this, re-create them, which will assign the correct types.
The scale operator no longer rescales float values, only coordinates (#840)
Removed deprecated operators
ggxMat, orenNayarMat, sdfToFloat (replaced with sdfField)

Instead of automatically using axis-based rotation when the input is 2d, instead use the mode parameter to choose between types (like for 3d). For 3d, only the Z axis rotation is used.

v0.21
Highlights
Editor actions are contextual actions available in a menu using the new ALT+SHIFT+R shortcut. They include things like:
Add common material elements when a modularMat is selected.
Add a lookAtCamera or pointLight when a raymarchRender3d is selected.
Combine selected SDFs or fields.
Navigating to the source of a variableReference.
Converting a vector field to a float field, and vice versa.
Exposing and binding parameters on the parent COMP.
Adding animation to parameters.
Transform sequences are a new way to apply groups of transforms to spatial coordinates or uv coordinates, including support for repeating the transforms in a loop! It’s like a much more flexible version of iteratedTransform.
Standardized SDF combine options across various ROPs that combine SDFs. This means that the full features like stair union with offset control are available in ROPs like flip or radialClone.
Standardized wave function options across various ROPs. This means that waveField, waveFunction, lfoField, etc all have the same wave shape options.
Control utility components are a set of general-purpose tools that can be used with RayTK or non-RayTK operators. Most of them have associated editor actions, including:
lfoGenerator which can be applied to any numeric parameter using the “Animate with LFO” action.
speedGenerator which can be applied to any numeric parmaeter using the “Animate with Speed” action.

v0.20
Highlights
Thumbnail images in the palette!
The palette now has a toggle to enable showing thumbnail images next to each type of operator. These make it easier to find the operators you’re looking for, and see what’s available. Not all operators have thumnbnails (e.g. it’s hard to represent things like floatToVector in an image).
Shortcuts in the palette.
Common operators now have shortcuts that can be typed into the palette for quick access.
Shortcuts are shown in the palette next to operator names.
Variables are a whole new way to control and vary the behavior of operators.
These will eventually replace Iteration.
They use more explicit connections and support multiple levels of values. For example, you can repeat a shape radially using modulorPolar, then repeat that in a grid using modulo2d, and the input shapes can be based on both the grid cell and the radial slice.
Operators that support them have a “Variables” parameter page with buttons to create references to them which can be used by upstream operators.

v0.15
Highlights
Materials in 2D rendering
2D SDFs can now be rendered using materials, instead of with conversions like colorizeSdf2d.
The sampledPointMat can be used with 2D shapes similar to how it works with pointMapRender.
Not all materials work for 2D shapes, and things like surface normals and lighting are not available.
Surface UVs
Surfaces can now have UV coordinates, which can be used by materials for things like texture lookups.
Some SDFs have a “UV Mode” option to generate shape-specific UVs, such as boxSdf and sphereSdf, as well as some 2D SDFs including rectangleSdf.
There’s a “UV” output from renderers that accesses the UV coordinates for each surface point in the rendered output. This can be used for things like applying textures using post-processing with TOPs.
UV coordinates can be assigned to any surface using assignUV, and modified using uvTransform.
UV coordinates can be accessed within materials using operators like uvField.
Surface colors
Surfaces can now have a “Color” attribute, which can be assigned using assignColor, either with a constant color or using a field.
Surface colors can be used by various types of materials.
Within modular materials (modularMat), the surfaceColorContrib operator provides access to the surface color values.
Background fields
The raymarchRender3d operator now has a “Background Field” parameter which can be assigned to certain types of fields.
The background field is used to calculate a color for rays that don’t hit any surface before they give up.
The atmosphereField is designed for use with the “Background Field” feature. It produces a simulation of a sky with a sun, including some advanced atmosphere-based coloration. It’s great for creating sunsets.
The texture3dField also supports being used as a background field. It can be used to apply environment lighting with cube-maps and other types of 3D textures.
The background color is used for reflection-based rays as well as primary rays, so the background colors will show up on reflective surfaces.
The rayField operator can be used within background fields to access the direction of the ray that hit the background, as well as in materials where it uses the ray that hit the surface.

Infrastructure / development
Large-scale restructuring of how data types are handled throughout the toolkit. Operators can now support multiple variations of coordinate, context, and return types, which downstream operators can restrict and eventually resolve to single concrete types.
The main user-facing result is that fields don’t need to specify their context type since whatever they’re fed into can automatically switch it to the right type.
v0.13
Highlights
Whole new modular material system!
Create customized combinations of different parts of materials.
Lots more options for filters, texturing, and field-based variation.
Improvements to support for 2D SDFs and ways to use 2D SDFs in 3D scenes.
Lots more documentation.
NOTE: The way that shadows are handled has changed. Shadows are no longer specified at the material level.
Instead they are attached to the “Shadow” input on raymarchRender3d.
Materials now have a “Use shadow” setting to opt them in/out of shadows.
