| Abstract: |
| This paper presents the implementation of a web application focused on the learning of computer graphics concepts with focus on camera, scene graph and geometric transformations, called CG-VisEdu. Its construction is based on some computer concepts in education, making its use more intuitive and efficient. The Three.js library is used as a key point to set up the exercises editor of the application and view their results in 3D space. The application provides a geometric shapes fitting game, where you can perform exercises through pieces that fit together coherently. Each piece works with a specific concept of computer graphics: camera, geometric transformations, scene graph and graphic objects (which is represented by a cube in the application). These pieces are displayed in an editor where it's possible create pieces and fit them together. As the pieces are fitted, it's possible view the graphic results obtained by the fittings in a 3D space. When a piece is selected, it's possible view the code in Java (using the JOGL library) that is needed to reproduce the concept represented by the piece, helping the student to understand the logical order of the commands used for the scene development. Firefox has been reported as the best browser to use the application on performance analysis, by supporting the largest number of pieces in one exercise. The usability analysis was taken from a questionnaire completed by students of computer graphics, which showed a very good performance of the application e and brought several contributions improvement. |
