Τρισδιάστατα γραφικάAbstract
Virtual reality is the representation of a real or fantastic environment which can be seen by the user in three dimensions. Virtual reality usually uses computers to create and represent virtual worlds. The sector of computer science which creates virtual worlds is called 3D computer graphics. The fact that in 3D graphics 3 dimensions are used makes them more realistic.
The progress in creation of virtual worlds and the increase of the abilities and speed of the internet made possible the creation of online virtual environments. One of the main characteristics of online virtual environments is the users’ interaction.
Website development technologies can use 3d computer graphics. This was made possible by the development of specialized technologies and platforms like shockwave 3D, hoops, java 3D, VRML and others. Every technology has its own strong characteristics.
In order to create the application of this paper firstly the website was created and then the 3D graphics. Finally the 3d graphics were embedded in the website. The stages of a website development are five. Analysis phase, development, test and production , maintenance and updating. The most crucial part of the previous procedure is the development phase and more precisely the code creation.
There are many 3d computer graphics creation and for the 3d application of this paper blender was used.
The main stages of 3d computer graphics creation are modeling, texturing, lightning and rendering.
The final integration of the 3D graphics in the website was conducted by embedding the 3D video with the html tag <video>. This choice may not offer much interactivity to the user but it is functional and presents all the information about the 3D building of the gym.
