Abstract: This paper aims to analyse how the accuracy of rendering 3D models on 2D surfaces is affected by using different real number representation inside different stages of a graphics pipeline. Also, an optimal format that would not alter the final product in a significant way was a target of our research. Additionally, a great number of 2D projections for each 3D Model is targeted. In order to achieve our goals, we have modified an own software implementation of the OpenGL ES 1.1 specification so that it could be easily specified which real number formats are used in each stage.
