Computer science at MIT is the engineering department at the Massachusetts Institute of Technology (MIT). Located in Cambridge, Massachusetts, the department is comprised of more than 2,000 students. Its undergraduates pursue a variety of degrees, from a minor in mathematics to a Ph.D. in computer science. Among its specialties are solid modeling and finite element method. During the course of their studies, MIT students will learn about such areas as computer graphics, 3D scanning, and geometry processing.

Computer graphics

While the subject of computer graphics has a long history, the field has become more commercialized and modern in recent years. Since the popularity of personal computers began to rise, computer graphics has become a popular subject, and the number of programmers and developers increased dramatically. Several fields are under the umbrella of computer science, including computer vision, robotics, and location-based entertainment. Listed below are just some of the main areas of research in the field.

Early computer graphics began as pure academic research and came from technological developments in the United States military. These technologies were largely non-interactive and required new forms of display to process information. Sutherland's work was ultimately instrumental in developing the HMD, which NASA would later use for virtual reality research. Sutherland and Evans became highly-respected consultants for large companies. The two eventually decided to launch their own computer graphics company.

Solid modeling

The use of 3-D solid modeling has numerous applications in engineering. This computer software can represent complex geometry, such as those of a cube, and calculate their attributes quickly. This software is very useful in a wide range of manufacturing applications, including reverse engineering, motion planning, NC path verification, and kinematic analysis. Solid modeling is a core component of computer-aided engineering. It has many benefits and is a key component of 3D-CAD.

The basic concept behind solid modeling is that each cell is a list of spatial cells. These cells are typically cubes of a fixed size arranged in a spatial grid. These cells may represent a single point, or a set of points. Each point is represented by a certain set of coordinates, and this order is usually imposed. This ordered set of coordinates is called a spatial array. This kind of representation is unique to a solid, but it is overly verbose to be useful for most purposes.

Finite element method

In 1962, the Berkeley campus computers were improved in speed and capacity, and they were first used to analyze a concrete dam. This research continued for several decades, until the finite element method was adopted in computing by industry and the government. It is now the most widely used numerical method in many fields, including computer science and engineering. MIT has made its teaching materials freely available online for all to access. The finite element method was developed by researchers at MIT and its impact can still be seen today.

The finite element method is a numerical computation method that takes into account a variational problem and a finite-element mesh to produce a system of discrete equations. Implementations of the finite-element method are highly specialized, usually handling a small set of finite elements and variational problems. The program's interface is also often parametrized, allowing users to choose a particular mesh.

3D scanning/geometry processing

A large portion of geometry processing research at MIT focuses on surfaces embedded in 3D, but there is also interest in volumes and higher-dimensional manifolds. These new methods are based on intuition gained from studying the lower-dimensional case. In this article, we will look at some of the current research in 3D scanning/geometry processing. In addition, we will briefly discuss a few applications for these techniques.

The main method of 3D scanning is called photogrammetry. This technique records objects from all sides. Its accuracy is highly controversial, but there is no standard range. The accuracy of the method is determined by how detailed the object is and what type of data it contains. For example, the Artec Eva scanner used on the Wismar Big Ship Project has an accuracy of 0.1 mm and geometric resolution of 0.5 mm. This accuracy is a step above what traditional shipbuilders were working at.

Parallel and multicore computer architecture

MIT researchers have developed an algorithm for parallel and multicore computing that divides memory into uniform-sized chunks. Each chunk points to up to 16 others. When a large data structure cannot fit in a single memory chunk, the system creates additional chunks and links them to existing ones. In this way, the system can efficiently access the cache. Nonetheless, there is still a risk of bottlenecks when multiple cores are working on one task.

The course covers fundamental philosophies of parallel programming and parallel computing, as well as emerging best practices. It also briefly examines the history of microprocessors and discusses the recent move toward multicore architectures. It also discusses the Cell processor that powers the PLAYSTATION 3 and compares it to other emerging architectures. The course's instructors are supported by IBM, Toshiba, and Sony.

Bayesian modeling

Students pursuing a degree in computer science can take a course in probabilistic modeling, a field that emphasizes the use of data to determine the best course of action. The course will teach students how to use a probabilistic programming framework and will give them exposure to core conceptual and theoretical issues in computer science. It will also provide students with a strong foundation in probability and its applications, as well as an introduction to Bayesian modeling.

In general, Bayesian statistical modeling is a powerful statistical method used by engineers and scientists to make decisions based on the data collected. Bayesian approaches combine various statistical methods into a single framework for prediction, estimation, and coherent uncertainty quantification. Moreover, this course will introduce students to contemporary challenges in Bayesian inference, including high-dimensional data, complex interactions, and distributed architectures. Bayesian models are effective tools for predicting the future, which makes them an important tool for data scientists and engineers.
