Robust Interior: Exterior Classification for 3D Models

The use of 3D models has been rapidly expanding, finding applications in both<br/>scientific and commercial fields. One common requirement for these various applications is the geometrical and topological validity of these models. However, many models available online contain deficiencies in various forms, such as duplicated geometry, gaps in...

Fast and accurate ray-casting-based view factor estimation method for complex geometries

The concept of view factor has various applications in engineering problems, ranging from heat management to bifacial photovoltaics. Analytical solutions for view factor calculations are difficult to obtain and normally numerical methods are used. For complex geometries, when several surfaces are arbitrarily arranged in a threedimensional...

An albedo irradiance model usable for bifacial PV modules based on LiDAR data and ray casting

Despite the fact that the price per watt-peak for photovoltaic modules are decreasing rapidly, there is a large population of people which have still not implemented photovoltaic technology in their everyday lives. An important reason why PV is still not the main source of electrical energy for these people is the uncertainty that comes with...
