....in 3 D Programming Two goals of 3 D programming are to represent program execution with 3 D graphics [34] and to enable the user to program using executable 3 D graphics. A brief review of two approaches to this problem, along with their use of metaphor, is given below. 3.4. 1 CUBE Najork s [35] CUBE is an example of a 3 D visual programming language that has a 3 D syntax. In CUBE, programs consist of an arrangement of 3 D shapes instead of a linear stream of text [35] The language is divided into two fragments [35] The first fragment consists of predicate definitions and logic ....

....similarity to type inference [11, 3] in that it reasons behind the scenes through static analysis techniques to find errors in combining values, but our approach is not based on types. In particular, we are not translating abstract type systems into visual languages as exercised, for example, in [14, 18]. Rather, like other research into units and dimensions [24, 9] the goal of our approach is to detect errors related to illegal combinations of units. However, unlike the other works on units, we aim to detect any such # This work was supported in part by the National Science Foundation under ....

....found in the fact that 3D interaction techniques [Han97] are a topic of ongoing research, and no standard means for interaction have emerged yet. Usability questions of interaction devices are also discussed, often without satisfying results. This situation is also stressed by a remark of Najork [Naj96], stating that usability problems precluded the use of others exploiting the graphical editor for his 3D language Cube , but the author did not provide any details. Difficulties with direct manipulation techniques such as dragand drop are discussed by Oshiba and Tanaka [OT99] in the context of ....

Najork [43] created the Cube language, with cubes representing program nodes and pipes for flow.

In reviewing algorithmic art, representing the former concept of ....

....editor that describes components of an animation in terms of hierarchical objects and actions on them such as transformations, modeling operations, deformations, particle systems and recursive procedures. Two virtual environment languages for programming that have been implemented are CUBE [6] and Lingua Graphica [10] CUBE allows visualization of expressions in a functional language, and some limited editing through a desktop based interface. Lingua Graphica is a 3D editor for a C based language. The Lingua Graphica workspace looks like a tool board with the tools being the various ....

....detected. 2.3.1. Static Types in VPLs Our search through VPL literature has revealed only seven VPLs that have incorporated static type inference. In about half of these VPLs, systems like Milner s are fully incorporated into the VPL, and hence static soundness is preserved. ESTL [30] and CUBE [31] are VPLs in this category. For example, Milner s type system has been incorporated into ESTL as follows. ESTL, an extended version of the dataflow VPL Show and Tell [32] has a feature termed consistency, with which values can be compared, conditions tested, etc. If such conditions are not met, ....

.... object oriented programming thoroughly discussed in [1] The extension lies in different encapsulation of objects and different usage of classes which is inherent to the NUT system [2] With this respect, our technique is similar to visual programming based on constraint nets [3] or data flow [4]. The novelty of the present work is, first of all, in a uniform representation of semantics of visual images and schemes composed from the images. We use images instead of icons for representing objects. An image includes, as a rule, a number of elements with their own meaning: buttons, ports, ....

....reasoning community. Our use of Venn Euler diagrams is centered on its computational aspects. We want to focus on simple diagrams with a clear computational interpretation, avoiding as many logical symbols as possible. There exist other visual declarative programming languages like CUBE [14], VEX [7] and SPARCL [23] but none of them uses sets, Venn Euler diagrams, and graphical containment as its foundations. In the Database field, most visual formalisms are applied to what is known as visual query languages and we do not know of any other formal visual language devoted to ....
