Why are 3D Transformations in Computer Graphics Difficult? An Analysis of a Decade of Exam Questions
Thomas Suselo, Burkhard Claus Wünsche, Andrew Luxton-Reilly · 2022
Three-dimensional (3D) transformations are a fundamental concept in Computer Graphics and are used for modelling, view transformations, animation, and efficient rendering. Understanding 3D transformations can be difficult, since they typically involve geometric concepts, mathematics, specific programming constructs (e.g. using graphics APIs), and visuospatial skills. While previous research investigated students’ problems with geometry in mathematics courses, we did not find any research investigating teaching and learning of 3D transformations in computer graphics.
