Method and computer program product for lighting a computer graphics image and a computer

The invention relates to a method to and a computer program product for lighting a computer graphics image to be rendered. It is assumed that a plurality of light sources illuminate one or more objects of the scene to be rendered thus causing a complex lighting situation. For reducing the complexity of the lighting situation and saving computing time the lighting condition is pre-calculated by approximating at least two and preferably all light sources by a single fictitious light source in a pre-calculating step. In the step of pre-calculating, there is computed an approximated light direction for at least two selected ones of the light sources and an approximated light color for the selected light sources by weighting color contributions thereof. The step of pre-calculating is performed for selected areas of a surface of objects present in the scene and results in coefficients that are stored, for these selected areas, in a lightmap or in vertices representing the object surface. The coefficients are retrieved by subsequent method steps for rendering the computer graphics image using the approximated light condition. The invention applies not only to diffuse lighting but is, with a minor modification, also of use for calculating specular lighting.

Method for operating a hearing device and hearing device

A method operates a hearing device for a user. In the method, electromyography is performed, in which a muscle activity of an auricular muscle of the user is measured by an electrode array. The muscle activity is continuously measured to detect a complex activity profile of the auricular muscle, in which the user's intention is coded. The electrode array generates a sensor signal that is classified by means of a classifier, and in this classification process, the muscle activity is decoded and the underlying intention is determined by examining whether the sensor signal has a previously known feature vector. The previously known feature vector is assigned to an operating mode of the hearing device, which is set when the sensor signal has the previously known feature vector.
