In addition, we achieve a significant speedup for ray-surface intersections by caching per-ray intersection points. We also present a technique for rendering sharp edges and corners in point-sampled models by introducing a novel surface clipping algorithm....
The clipping algorithm operates on floating point values. Perspective projection is used to perform foreshortening so that he farther an object is from the viewport, the smaller it appears in the final image. This occurs because the viewing volume for a perspective projection is a frustum of a ...

In addition to point positions, we augment MLS with a formulation that also considers colors and normals, updated at each iteration. Our algorithm iterates between the three steps described below. 1. Find point neighborhood. For each point Pi, we define its neigh- borhood N (Pi) as a ...

Point cloud registration is a fundamental problem in computer vision, which is extremely challenging for LiDAR point clouds with a lot of noise, outliers, and poor initial position. To deal with these difficulties, this paper proposes a semantic-based iterative closest point algorithm, which utilizes...
Clipping: I think shader modification could do it (hide or use different color, if point coordinate is not inside given coordinates), but having lots of separate boxes wouldnt work so well on this.. Or actually could probably adjust from script the invidual point colors, not sure how slow ...

Block406contains the clipping, perspective, and viewport application. Clipping refers to the elimination of the portion of a geometric primitive that is outside the half-space defined by a clipping plane. The clipping algorithm operates on floating point values. Perspective projection is used to perf...
CPU 208 then performs a model fitting algorithm by processing the determined set of keypoint information matches to build the model. The model fitting algorithm may be designed to discard false matches during the model building process. The model fitting algorithm may be based on, e.g., the ...
