Systems and methods for optimizing a model file

Abstract

Systems and methods for optimizing a model file include an occlusion reduction process. The occlusion reduction process includes acts of: (i) identifying points on a mesh section of a model, (ii) casting a set of rays toward the points, (iii) determining a number of rays that reach the points without being occluded by a portion of the model or a portion of another object, (iv) determining occlusion values for the points based on the number of rays that reach the points without being occluded; (v) determining whether the occlusion values for the points satisfy a predetermined occlusion threshold value; (vi) removing the mesh section from the model in response to determining that the occlusion values satisfy the predetermined occlusion threshold value, and (vii) refraining from removing the mesh section from the model in response to determining that the occlusion values fail to satisfy the predetermined occlusion threshold value.
