RayTK library 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.
