RELAP5-3D is an outgrowth of the one-dimensional RELAP5/MOD3 code developed at Idaho National Laboratory (INL) for the U.S. Nuclear Regulatory Commission (NRC). The U.S. Department of Energy (DOE) began sponsoring additional RELAP5 development in the early 1980s to meet its own reactor safety assessment needs.
LOD is found in GIS and 3D city models as a similar concept. It indicates how thoroughly real-world features have been mapped and how much the model adheres to its real-world counterpart. Besides the geometric complexity, other metrics such as spatio-semantic coherence, resolution of the texture and attributes can be considered in the LOD of a ...
The Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. [1]Blinn–Phong is a shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixel values between vertices are ...
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
As a sort of Easter egg and last personal tag, the artists and developers decided to add a 3D model of a chimpanzee head (called a "monkey" in the software). It was created by Willem-Paul van Overbruggen (SLiD3), who named it Suzanne, after the orangutan in the Kevin Smith film Jay and Silent Bob Strike Back .
A triangle is considered poor-quality if it has a circumradius to shortest edge ratio larger than some prescribed threshold. Discovered by Jim Ruppert in the early 1990s, [4] "Ruppert's algorithm for two-dimensional quality mesh generation is perhaps the first theoretically guaranteed meshing algorithm to be truly satisfactory in practice." [5]
OpenGL (Open Graphics Library [4]) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.
The first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, [1] it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth ...
