Claim 0:
1. A method comprising:
controlling an image projection system of an additive manufacturing system using an image display subsystem, wherein the image projection system comprises a plurality of image projectors;
projecting a composite image onto a build area within a resin pool of the additive manufacturing system using the image projection system, wherein the composite image comprises a plurality of sub-images arranged in an array, and wherein the projecting the composite image comprises projecting each sub-image onto a portion of the build area using one of the plurality of image projectors; and
adjusting properties and aligning a position of each sub-image in the array using a set of filters comprising:
an irradiance mask that normalizes irradiance;
a gamma adjustment mask that adjusts sub-image energy based on a reactivity of resin in the resin pool; and
a warp correction filter that provides geometric correction.
