ped - A Physics Engine Editor
نویسندگان
چکیده
This work presents ped – the physics engine editor. It builds on the existing pe framework to compute rigid body simulations, and introduces an interactive tool to set up, manipulate and examine pe world simulations, via a flexible and easy to use GUI. While in the original pe it is only possible to construct arbitrary simulations in the form of hardcoded programs, ped offers an interactive and freely modifiable simulation world. The ped interface provides the functionality to place any pe primitives and self-built union bodies, as well as offering several tools to easily set up large scale simulations, like structural templates and body generators. During the actual course of the simulation, ped supplements pe with an all-new timeline mechanism, which allows the user to freely regulate the flow of time of the simulation: The user may just watch the simulation unfold, or choose to jump to any specific time step at will. Simultaneously, additional bodies may be added at any time of the simulation, as well as existing bodies being modified or removed. Additionally, specific bodies may be selected and traced over the course of the simulation, to follow their route through the simulation world as time passes. The ped package is rounded off by various additional functions, such as storing complete simulations to hard disk, an easy to use union editor, and several display options to illustrate the current state of the simulation.

Integration of a Physics Engine into an Adventure Game Platform
This paper presents the challenges and possibilities that arise from the integration of a 2D physics engine into an adventure game platform (i.e. engine and editor). This integration allows the use of a complex physics model within a narrative environment, thus increasing expressiveness and educational potential (through re-usability and increased challenge). In this work eAdventure is used as ...
متن کاملμ Max-Unity3D Interoperability Toolkit
Object-oriented rapid prototyping tools geared towards multimedia, such as Max/MSP/Jitter and Pd/Gem, serve as a powerful foundation for efficient multimodal crosspollination and integration. Although both Max and Pd support OpenGL, the lack of scalability, user-friendly 3D editor, and physics engine makes them less desirable solutions for the rapid development of complex environments and physi...

Real-time photoacoustic and ultrasound imaging: a simple solution for clinical ultrasound systems with linear arrays.
Recent clinical studies have demonstrated that photoacoustic imaging (PAI) provides important diagnostic information during a routine breast exam for cancer. PAI enhances contrast between blood vessels and background tissue, which can help characterize suspicious lesions. However, most PAI systems are either not compatible with commercial ultrasound systems or inefficiently deliver light to the...
