Relato de Experiência Sobre o Aprendizado de Introdução à Renderização Baseada em Física em um Curso de Graduação da Área de Computação

Abstract

Este artigo apresenta um relato da experiência do estudo da disciplina de Introdução à Renderização Baseada em Física (IRBF) em um curso de graduação da área de computação. Ao longo deste trabalho, é ressaltada a importância da disciplina na motivação dos alunos e no combate à evasão escolar. Também é traçado um paralelo entre os conceitos abordados ao longo da disciplina e as disciplinas estudadas ao longo do curso de graduação. Ao final, discutem-se os pontos positivos e negativos da experiência e são apresentadas sugestões para as futuras ofertas da disciplina de IRBF.

How to Increase Interest in Studying Functional Programming via Interdisciplinary Application

“…This rendering technique traces the path of light, converting it to pixels in an image plane, as a way of simulating the effects of multiple light rays interacting with primitives in a virtual environment ( Figure 1). Its inherently interdisciplinary background, covering multiple topics spanning both Mathematics and Physics, has shown to be a motivational application of theoretical concepts which are considered hard to understand according to undergraduate students [9]. Implementing this algorithm in the context of education in functional programming courses can also demonstrate how well languages in such a paradigm could handle parallel programming [6,8,10].…”

“…Implementing this algorithm in the context of education in functional programming courses can also demonstrate how well languages in such a paradigm could handle parallel programming [6,8,10]. With ray tracing, considered to be an "embarrassingly parallel" [9] problem, the implementation of such features as well as the understanding of students would be facilitated.…”

“…As it is currently used within a multitude of fields such as engineering, medicine, and data visualization, ray tracing [9] can have a motivational appeal to students. Realizing that, by learning functional programming concepts, one can be a part of a ray tracer software project brings meaningful examples of its importance.…”

“…They are responsible for generating a ray for every pixel in the final image to be later intersected against the list of triangles in the scene. ONB [9] is an auxiliary module whose task is to generate a matrix used for transforming a ray from the simplified camera space, where it is created, to the world space, where the scene (list of triangles) is located. In performing such a task, it uses Vector3 and Matrix3 operations defined in the VectorOverloading module.…”
