MRTK-Unity vs. Oracle NoSQL Database vs. Unlambda vs. VisionLib Comparison Chart

MRTK-Unity is a Microsoft-driven project that provides a set of components and features, used to accelerate cross-platform MR app development in Unity. Provides the cross-platform input system and building blocks for spatial interactions and UI. Enables rapid prototyping via in-editor simulation that allows you to see changes immediately. Operates as an extensible framework that provides developers the ability to swap out core components. A button control that supports various input methods, including HoloLens 2's articulated hand. Standard UI for manipulating objects in 3D space. Script for manipulating objects with one or two hands. 2D style plane which supports scrolling with articulated hand input. A script for making objects interactable with visual states and theme support. Various object positioning behaviors such as tag-along, body-lock, constant view size, and surface magnetism. Script for laying out an array of objects in a three-dimensional shape.

Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.
