"Perancangan model 3 Dimensi dari sebuah kampus untuk keperluan visualisasi lokasi dapat dilakukan dengan pemindaian secara 3 dimensi. 3D Gaussian Splatting merupakan teknik pemindaian objek 3 Dimensi menggunakan 3D Gaussian sebagai representasi data volumetric dari proses Structure-from-Motion yang di konversi menjadi splats sebagai representasi objek yang memiliki data warna dan intensitas yang membentuk sebuah citra digital dengan akurasi warna dan posisi, dan detail objek yang tinggi. Untuk melihat render dari 3D Gaussian viewer berbasis web yang dapat menggunakan library ThreeJS. Menggunakan metode 3D Gaussian Splatting sebuah model kampus virtual 3D dapat diciptakan dan dilihat melalui aplikasi web dengan library ThreeJS . Hasil dari pembuatan model 3D Gaussian Splatting tersebut adalah rata-rata waktu training 9,49 menit dan hasil dari pengembangan aplikasi web tersebut menghasilkan rata-rata framerate 111 FPS.

Designing a 3 dimensional model of a campus for location visualization needs can be done using 3 dimensional scanning. 3D Gaussian Splatting is a 3 dimensional scanning technique using 3D Gaussians as a representation of volumetric data from Structure-from-Motion process that is converted into splats as the representation of objects with color and intensity that creates a digital view with high accuration of color, position, and object detail. To see the render of 3D Gaussian Splatting a web based viewer can be used using the ThreeJS library. Using the 3D Gaussian Splatting method a 3D model for virtual campus can be created and viewed using a web application by utilizing ThreeJS library. The result of creating the 3D model using 3D Gaussian Splatting is an average training time of 9,49 minutes and the result of the development of the web based application is an average framerate performance of 111 FPS."

"Komponen otomotif, terutama casing dan mounting umumnya memiliki bentuk yang sangat rumit. Perancangan dari awal akan memakan banyak waktu, namun dapat dihindari dengan proses rekayasa balik. Komponen yang direkayasa balik pada penelitian ini adalah casing transmisi Nissan March. Metode yang digunakan adalah pemindaian tiga dimensi dengan menggunakan Faro Arm dan Geomagic Studio. Permukaan komponen dipindai untuk mendapatkan titik - titik koordinat x, y, z persatuan jarak tertentu. Data titik ini dibentuk menjadi model polygon dengan proses triangulasi. Model polygon disempurnakan dan dijadikan dasar untuk pemodelan permukaan CAD dengan metode parametrik dan NURBS. Model CAD kemudian digunakan untuk pembuatan cetakan, estimasi kebutuhan material, dan berbagai simulasi.

Automotive components, especially casing and mounting, have very complex geometry. Normal design procedure will take too much time, but it can be avoided by doing reverse engineering process. Component that is reverse engineered in this research is Nissan March transmission’s case. The method is 3D scanning using Faro Arm and Geomagic Studio. Component’s surfaces are scanned to get x, y, z coordinate points at every certain distance. This point clouds are used to make a polygon model with triangulation process. Polygon model is refined and used as a base for CAD surface modeling with parametric and NURBS methods. Then the CAD model is used for dies modeling, raw materials needs estimation, and many kinds of simulations."

"The book discusses the theoretical fundamentals of CAD graphics to enhance readers’ understanding of surface modeling and free-form design by demonstrating how to use mathematical equations to define curves and surfaces in CAD modelers. Additionally, it explains and describes the main approaches to creating CAD models out of 3D scans of physical objects. All CAD approaches are demonstrated with guided examples and supported with comprehensive engineering explanations. Furthermore, each approach includes exercises for independent consolidation of advanced CAD skills. This book is intended for engineers and designers who are already familiar with the basics of modern CAD tools, e.g. feature based and solid based modeling in 3D space, and would like to improve and expand their knowledge and experience. It is also an easy-to use guide and excellent teaching and research aid for academics and practitioners alike."
