The invention relates to a method for producing a homogenized light quantity distribution with a spatial light modulator, which has a plurality of addressable, tiltable micromirrors arranged in rows and columns, in which the light from a flood light source is projected by an optical system and an illumination pattern of the projected light source is guided over a projection surface, wherein a plurality of pixels increasing in number towards the centre of the image are not illuminated so that homogenization of the light intensity of all pixels illuminated on the projection surface is achieved over a time integral. The invention also relates to a rapid prototyping method in which a liquid, light-curing plastic is illuminated by a method of this kind, is preferably illuminated with UV light, wherein the illumination pattern is projected on the surface of the plastic, and the plastic is cured by the lighting in the illumination pattern.
