ABSTRACT:
A system, device and method are disclosed for predicting the opacity of primitives used to produce an image using one or more equations, prior to producing an image. More specifically, the present invention relates to a 3D device adapted to produce an image comprising an opacity estimate predictor adapted to predict opacity of at least one primitive using at least one first equation and further adapted to reject the primitive if the predicted opacity is equal to a minimum value.
