What is Rational Reducer?
Rational Reducer is an application to help you reduce the complexity of your 3D models and scenes, thereby making them fit for use in real-time visualization environments.
Here is an example of what you can accomplish on a typical 3D model. Please take a closer look at the watch we have reduced dramatically:
The main goal of Rational Reducer is to automatically preserve the visual quality as much as possible while the user tunes the polygon count to suit his needs.
Who should use 3D Rational Reducer Professional and why?
As an example, let us say that you create simulators. To optimize for real time rendering you need to create different levels of detail for your 3D models. The manual optimization of one model for three different layers of detail takes you on average *two days*, and it is not a very interesting job. With Rational Reducer Professional this can be done automatically and within minutes.
Examples of use and users:
Web content providers and designers
To minimize download and rendering time. According to Fortune, the use of 3D content on the web increases on-line sales by 25%.
Entertainment, infotainment and edutainment producers who use 3D graphics in games and educational software
To enable the use of existing CAD models in stead of creating new models from scratch.
To optimize animation smoothness with minimum trade-offs.
Manufacturing industry
To reduce the size of CAD models to enable distribution to customers and/or co-workers.
Providers of simulator systems
To automize the optimization process when creating different layers of detail and to save days per model.
Automatic vs manual polygon reduction
Sometimes there are advantages by doing your model optimization by hand, like when you are on an extremely tight polygon budget. Usually, though, there is a vast number of important advantages to doing it automatically:
The whole process of basic performance tuning becomes much faster when you can do it automatically, and you can release the manpower spent on this task to do creative work instead.
Hand tuning the polygon count of a model is dead boring. Graphics artists are creative types and usually hate this kind of work, "ruining" their own creations because the computer is not up to the task of visualizing their masterpieces.
A valuable side-effect of being able to reduce the number of polygons quickly is that you can easily gradually tune the model down to the minimum complexity; you just reduce with a higher percentage grade until the model starts looking "too bad" instead of "still OK". Then you just go back and reduce it a little less. This is hard to do in a general way when hand tuning.
Doing automatic reduction means you can better take advantage of the geometric properties of the models, e.g. straightening slightly curved surfaces might save you a lot of polygons, but this is an operation which is difficult and tedious to perform by hand. At the same time, you are also able (by some mathematical "magic" on Rational Reducer's part) to preserve some of the important characteristics of the model, like total volume.
Generating several levels of details of the same model is very easy and quick when compared to doing it by hand. Having different complexity levels of the same model is usually something which can be automatically handled by most real-time graphics systems, i.e. when your model is closer you use a version of the model with a high polygon count, while when it is further away you can use lower-level complexity versions.
Common problems with automatic systems
We have checked out the majority of the few available systems comparable or partly comparable to Rational Reducer, and noticed that they have numerous problems:
Some are too slow.
Some leaves the users with way too low quality for serious use.
They don't keep a number of important attributes of the model, like color, material or texture mapping.
There's usually improper support for the model file format, and because of this they destroy too much of the internal model hierarchy.
The user interface is too complex and user-unfriendly when it comes to taking advantage of high-quality options.
We hope to have addressed all of these issues with Rational Reducer. If you bump into any area which Rational Reducer seems to be weak on, please let our support division know about it at support@sim.no, and as far as it is possible, we will promise to provide a solution within a short period of time.
