Interactive rendering of NURBS surfaces [PDF]
Computer-Aided Design, 2014 [Resumo] As superficies NURBS (Non-uniform rational B-splines) son unhas das primitivas más empregadas no modelado de alta calidade nas ferramentas CAD/CAM e o software gráfico. Dado que a avaliación directa de superficies NURBS na GPU é unha tarefa altamente complexa, a aproximación máis común para o render de NURBS é a súa conversión previa na CPU en
