The quadratic upper bounds are also appreciated by the computer-graphics literature: Ghali notes [15] that the algorithms by Devai and McKenna "represent milestones in visibility algorithms", breaking a theoretical barrier from O(n 2 log n) to O(n 2) for processing a scene of n edges. The other open problem, raised by Devai, [4] of whether ...
SketchUp is a 3D modeling software that is used to create and manipulate 3D models. It is used in architecture and interior design.. SketchUp is owned by Trimble Inc. The software has a free web-based version, and three paid subscriptions to gain access to applications for Windows and macOS.
It allows SketchUp to view EnergyPlus input files in 3D. The plug-in allows users to mix EnergyPlus simulation content with decorative content. [3] The plug-in adds the building energy simulation capabilities of EnergyPlus to the SketchUp environment. Users can launch an EnergyPlus simulation of the model and view the results without leaving ...
In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space.
Due to discontinuities in the surface normal, a silhouette edge is also an edge which separates a front facing face from a back facing face. Without loss of generality, this edge is usually chosen to be the closest one on a face, so that in parallel view this edge corresponds to the same one in a perspective view. Hence, if there is an edge ...

This method uses multiple thresholds to find edges. We begin by using the upper threshold to find the start of an edge. Once we have a start point, we then trace the path of the edge through the image pixel by pixel, marking an edge whenever we are above the lower threshold. We stop marking our edge only when the value falls below our lower ...
