Abstract
The invention relates to a method for estimating information representative of a pixel of a virtual object. In order to improve the rendering while minimizing the required calculation time, the method comprises defining a first surface element associated with the pixel according to a direction of observation of the virtual object, the first surface element belonging to a representation of the virtual object according to a first level of detail; associating a second surface element with the first surface element, the second surface element being determined by intersection between the direction of observation and a first parametric surface representing the virtual object according to a second level of detail; estimating the information representative of the pixel according to the second surface element and information associated with the second surface element enabling the virtual object to be represented according to a third level of detail.
