CAD Modeling and CAE Simulation
Published in Jose Martin Herrera Ramirez, Luis Adrian Zuñiga Aviles, Designing Small Weapons, 2022
Jose Martin Herrera Ramirez, Luis Adrian Zuñiga Aviles
The software for modeling and simulation is included in the 3D computer graphics software, and due to its evolution and the new requirements of immersion, interaction, and imagination, today it is related to the virtual reality (VR) software. This software is classified as shown in Figure 4.2, where the usability testing and training focus on the user model and the firearm and test bench refer to the environment model.
Contending Philosophical Frameworks Within Artificial Intelligence

From the chromosome/coding vector, the genetic algorithm should be able to construct the phenotype, in this case a full facade, typically within a 3D computer graphics software. The most crucial issue in the algorithm is the fitness. It is a function that should take as input a phenotype, and return a real value that measure how good the solution is. In our case, the fitness is evaluated by simulating the exposure of the building to a variety of daylight conditions over a year and over different times of the day, and measuring several aspects of the internal illumination, taking into account also other aspects such as enegy saving.
Hologram calculation

We now explain how to calculate a hologram by the multi-view image approach. First, we generate multi-view images in some way (Figure 3.20). Representative multi-view image generation methods include a method of moving a camera, using a lens array, and using a plurality of cameras (camera array). If we physically use lens arrays and cameras, we can capture real-world multi-view images. On the other hand, if we move a virtual camera in 3D computer graphics, we can generate a multi-view image of the 3D graphics.

Videos were captured with both cameras at the same time using a frame rate of 25 and a shutter speed of 50 with variable aperture. Both the cameras were not synchronized mechanically or electronically; however; their position was aligned to get the best possible overlapping images for tie point measurement during triangulation. The videos were quality controlled for any blurring or smearing effect. The vehicle speed was kept below 20 km/h throughout the data capture. The road corridor for the area of interest was subdivided into 11 segments, and video acquisition was done separately. The overlapping imagery found during video acquisition was marked for elimination at a later stage of processing. The two cameras were positioned at a set distance apart to create a stereo setup that can capture stereoscopic views with ≥60% lateral overlap and 80% of forwarding overlap along the vehicle track. Using a mobile mapping vehicle travelling at 20 km/h in an urban area, and the camera’s frame rate of 25, stereoscopic views at 5 m intervals can be acquired efficiently with this technology (Ferrer-González et al. 2020). Splitting of the images from videos are carried out using Blender Software. Blender is an open-source software primarily used for 3D computer graphics. It is used in 3D modelling, texturing, video editing and animation as well.
