Computations & Graphics, Inc. (CGI)

was established in April 2002 and is located in the beautiful suburb of Denver, Colorado, United States. Since day one, its mission has been to develop practical, accurate, easy to use and affordable software for average structural engineers who do not have time to study and operate very complex structural analysis and design software.

We have many significant differences from our competitors. For example, our software is written from ground up in modern objected-oriented C++ language instead of some old FORTRAN code wrapped in yet another poorly designed programming language. This makes our software more robust and easier to maintain. Our software uses the industrial-strength OpenGL(R) graphics engine instead of some home-made graphics routines. This means our graphics is more stable and visually compelling. And because OpenGL(R) takes advantage of modern graphics card hardware acceleration, it also means our software runs much, much faster.

We recognize that accuracy and reliability are of utmost importance to engineers. We therefore strive to provide engineers with software that produces most accurate and reliable results. The unique 128-bit floating point solver in Real3D-Analysis is a great example! It rises in accuracy above the industry standard 64-bit floating point solvers. Many ill-conditioned problems under 64-bit solver become solvable under our 128-bit solver. Another example is our concrete column design module which uses exact method to compute P-Mx-My interaction diagram and surface instead of some approximate or empirical methods. Of course, our unique and blazingly fast concrete design solver will save your precious time too!

We believe good software must be designed with usability and good taste in mind. For example, our software allows you to input data graphically via mouse-clicks or numerically via spreadsheets or both. And yes, it also allows you to enter input through command window! Our software offers multiple document interface, that is, multiple files can be opened and worked on simultaneously. This means you can exchange data and compare results more easily. The feature sounds simple and reasonable, but very few engineering programs out there offer that! Unlike our competitors's rudimentary and blackbox approach, we provide true area load definition. You will like the flexibility in Real3D to convert area loads to line loads, knowing the software does what you expect it to!. How about using our RcSections to create your very own concrete column design PDF handbook similar to CRSI Handbook but with actual P-M interaction diagrams? We challenge you to find another program that can do what our software does in the market today!

CGI takes pride in its innovations and invites you to join hundreds of people who have already benefited from using our software.
