This article is written by Kobayashi, Associate Professor of Arizona State University to introduce City Design tool, which was released by FORUM8. I am going to develop tools for the seamless data generation and exchange between VR software package UC-win/Road by FORUM8 and other 3D CG packages. Source code of the tool introduced here is open to public, however since we are not offering support services, we cannot take responsibility for issues such as bugs. Thank you in advance for your understanding. I would like to hear from people in the architectural and civil engineering industries on your needs for concise tools suited for your system. |
Why city generation tool now? |
Let me introduce the background of the development of the tool. Originally
I have been interested in generation process of the 3 dimensional city
model and have been studying how I can reconstruct the existing cities
as digital data easily. During my PhD course, I developed a tool for the
generation of city models from aerial photos, using technology of image
recognition as well as neural networks, artificial intelligence and machine
learning. However I am intentionally away from the development of design tool using artificial intelligence. My theory is "performance of the design tool depends on how high-impact design products can be produced with the tool. Even when I develop new technologies, the development activity of the design tool cannot be highly valued as "research" if I cannot demonstrate something exceeding what people are accustomed to by watching Hollywood movies. . For example, there is a tool called CityEngine developed by Procedural company. I believe why this tool draws attention is because of the tool's ability to demonstrate the impact of its city model, which is unbelievably precise and sophisticated on top of its ability to be produced automatically. What I am aiming to achieve with CityDesign is the tool development which demonstrate the impact by a technology engineer. The keyword is "speed". I'm interested in a tool development: "Using the new technology which realizes dramatic time reduction and cost for something which can be possible with existing technology". It is rather a development of a framework which simplifies the design process while maintaining flexibility than a development of new technology. I am aiming at acceleration, not to the extent that "quick production allows the cost reduction per unit and the offering of products at cheaper prices", but to the extent that possible to meet the request of "completion by tomorrow with the 3-10 times the cost". |

Try MaxScript! |
In 3ds Max, a language called MaxScritpt is available, which allows you
to develop your own tool concisely. Many programmers seem to imagine "script",
a simple language used to write code easily. Of course I agree with the
technical definition of script which can perform functions that are hard-coded,
while I have a different opinion. In fact, the script of the latest CG
package" is a very strong "Thinking Tool". I am evaluating
it because we can edit basic vertex, edge and face in the mesh with flexibility,
rather than using a complicated geometry operation function. The tool is
often used in creating actual Hollywood movies. Some readers might have studied program in computer science in 1980s or early 1990s. At that time, written code, as is in LISP and Prolog was continuously stored in memory, and was able to perform the update of data and function was done interactively and flexibly. Even the simple list operation such as CAR and CDR can solve many issues of artificial intelligence. I am very sorry that programming skills has become the simplest issue of memory how many functions do they know, such as MFC (Microsoft Foundation Class) and OpenGL. Let's get back to the theme, MaxScript can manipulate the 3D data like we did with list manipulation of MaxScript. You can realize choosing the meshes which meets the condition with the cord of 2-3 lines, and creating another geometry data in high-end CGpackage. I would like you to experience the reduction of time and effort, or joy of the programming with mathematical way of thinking in 1980s. |

I would like to introduce following tools.
Please look forward to the next issue |
