This required a major re-modularization of OpenGL support on all levels, from basic window-system specific interface to medium-level object-representation and top-level scene management. OpenGL has been promoted to become the main 3D rendering engine of the ROOT framework. The new generation of OpenGL support in ROOT The most important conclusion of this work is that server side applications can easily take advantage of fast GPU and produce efficient results of advanced computation just like the visualization.
NET ASP, Java and Mono were used with specific OpenGL libraries to visualize tree-dimensional medical data. In this article construction and potential of OpenGL multi-user web-based application are presented. OpenGL in Multi-User Web-Based Applications It can run a batch sequence of commands (GLVis scripts), or display previously saved socket streams. GLVis can also be used to visualize a mesh with or without a finite element function (solution). This way the results of simulations on a remote (parallel) machine can be visualized on the lical user desktop. When started without any options, GLVis starts a server, which waits for a socket connections and visualizes any recieved data. GLVis is an OpenGL tool for visualization of finite element meshes and functions. OpenGl Visualization Tool and Library Version: 1.0 An algorithm is presented that allows the exact time of stimulus presentation to be deduced, even if there are relatively large errors in measuring the display time. A test of this system is reported that demonstrates that stimuli may be consistently displayed with millisecond accuracy.

A simple C program is presented to illustrate how this may be done within X Windows using the OpenGL rendering system.

This article describes how to display stimuli with millisecond accuracy on a normal CRT monitor, using a PC running Linux.
To measure people's reaction times to the nearest millisecond, it is necessary to know exactly when a stimulus is displayed. Millisecond accuracy video display using OpenGL under Linux. Finally the application of FROG for physic experiment/environement, such as Gastof, CMS, ILD, Delphes will be presented for illustration. This documents describes the features and principles of Frog version 1.106, its working scheme and numerous functionalities such as: 3D and 2D visualisation, graphical user interface, mouse interface, configuration files, production of pictures of various format, integration of personal objects, etc. Moreover, Frog does not require installation of heavy third party libraries for the visualisation.

The code is light (< 3 MB) and fast (browsing time ~ 20 events per second for a large High Energy Physics experiment) and can run on various operating systems, as its object-oriented structure (C++) relies on the cross-platform OpenGL and Glut libraries. It is suitable to any particular physics experiment or detector design. Here is an example of how one of the resulting polygons could look like:Įdit: I thought today that one possible algorithm would be to arrange the polygon points regular (for instance as an rectangle) and then reposition them in x-y-directions to a random amount, while checking that the generated lines are not cut.įor (let i = arr.Frog: The fast & realistic OpenGL event displayerįROG is a generic framework dedicated to visualisation of events in high energy physics experiment. I do not have any idea how to determine the next point for the connecting line, so that it does not cut any other line.įurther, the last point must close the polygon. Return Math.floor(Math.random() * (max - min + 1)) + min Here is an intial code which only draws a complex polygon (lines intersect): var ctx = document.getElementById('drawpolygon').getContext('2d') The number of sides should be defined by the user, n>3. I am trying to find an algorithm of how to draw a simple (no lines are allowed to intersect), irregular polygon.
