Abstract: Various approaches to performing non-divergent parallel traversal operations for a bounding volume hierarchy (“BVH”) during ray tracing are presented. For example, a computer system has a processing unit with threads that, collectively, perform ray tracing for a group of rays in parallel in a computer-represented environment, which includes geometric objects (such as triangles) enclosed in the BVH. Each of the threads receives parameters for a given ray and traverses the BVH to determine an intersection, if any, between the given ray and one of the geometric objects. The order of traversal of the BVH is synchronized between threads for the rays of the group, for example, using a cross-group operation such as a ballot operation. In this way, the overall speed of the BVH traversal can be improved in many cases, while avoiding code divergence and data divergence in extra-wide single-instruction, multiple data (“SIMD”) graphics processing unit (“GPU”) architectures.

Abstract: During tracing of a primary ray in a 3-D space (e.g., a 3-D scene in graphics rendering), a ray is found to intersect a primitive (e.g., a triangle) located in the 3-D space. Secondary ray(s) may be generated for a variety of purposes. For example, occlusion rays may be generated to test occlusion of a point of intersection between the primary ray and primitive is illuminated by any of the light(s). An origin for each secondary ray can be modified from the intersection point based on characteristics of the primitive intersected. For example, an offset from the intersection point can be calculated using barycentric coordinates of the intersection point and interpolation of one or more parameters associated with vertices defining the primitive. These parameters may include a size of the primitive and differences between a geometric normal for the primitive and a respective additional vector supplied with each vertex.

Abstract: Shadow is computed in a lighted 3D scene, based on a depth map. For each depth map element, following geometric information is stored: depth value, coordinates of vertices and local depth variation of a surface element. Also, ray intersection is tested for a pixel with the surface element having depth computed from the depth and local depth variation, taking into account the coordinates of vertices. A minimum depth associated with the surface element is further computed from the geometric information, with which the depth of a pixel is compared. The pixel is classified as lit if the depth is lower than the minimum depth, and as shadowed if the depth is greater and if a ray intersection is found for the pixel with the surface element from the ray intersection testing. The invention can provide a fast solution for high-quality shadow.

A triangle mesh generator (107) positions an internal vertex within each region of the k-D tree. The triangle mesh is then generated by forming sides of triangles of the triangle mesh as lines between internal vertices of neighboring regions. The approach may generate an improved triangle mesh that is suitable for many 3D video processing algorithms.

Abstract: An improved part optimization process in additive manufacturing is provided, which uses a finite element analysis only where boundary parameter differentiation is detected. For a given part being manufactured, such as in DMLS, thermal effects of adjacent volumes with no boundary parameter differentiation are ignored in the part optimization process. For example, if a given volume is over a volume of the same material, no computational analysis is conducted, but if a volume of metal is over air, then the computational analysis is conducted. This results in significantly less computational time being required. Further, the present invention uses computation equipment remote from the DMLS part production equipments, connected instead via the internet or other such “cloud computing” arrangements.
