Drawtex SCV: uma ferramenta educativa para a composição de primitivas gráficas OpenGL com exportação de código C/C++

Abstract

Considering the difficulty of learning, as an OpenGL programmer, the effect of the several internal state variables of this API in a rendered scene, as well as the difficulty of composing three-dimensional objects in code description of OpenGL calls; this project aims to produce an educational tool to allow the composition of graphic primitives in an educational environment that focuses on concepts of OpenGL. Thus, in order to step over these difficulties, the objective of the present work is to produce a C/C++ code exportation feature from an editing and visualization interface of 3D vertexes and primitives. The project followed and incremental pattern, counting with the building of a prototype before the final implementation started. This allowed for modularization and ease of future expansion. The SCV API for the composition of GUIs was applied, in order to validate its use in more complex software. The results satisfy the proposed objectives, and the project presents various possibilities of expansion.
