Parametric Array
Recently we have been working on several projects that required to improve our modeling tools. It led us to develop a new version of array tool in 3ds Max. One of the most challenging tasks in 3ds Max is to deal with a series of replicated objects. 3ds Max has an array function that allows you to clone entities in three dimensional space.
Parametric arrays. Arrays of sources (or receivers) of sound formed by variation of appropriate parameters of the propagation medium. Normally, these parameters are the local sound speed and the particle velocity which vary because of the presence of large-amplitude pump, or primary, sound waves. Hi, I'm trying to create a parametric array in a family. However I'm getting continuously message that constraints are not satisfied. If I have just.
Beside that there are other commands to replicate objects such as Snap shot and Spacing tool. All array commands in 3dsMax let you to decide on the number of items as well as other settings while you are making the array. After you exit from the dialog box, 3ds Max generates the clones and you are no longer able to add or remove items or change the settings. In fact 3ds Max doesn't make any dependency between the clones. We realized that the main concern about arrays is to have control on the number of members. Furthermore accessing to properties of the items based on their position in the array can help us to transform the items in into a variety of ways. We have designed a helper object that not only offers all types of the array but also allows you to change the settings of the array.
The package contains two script files.All you need to do is copying them under your max script/start-up folder. Parametric array offers many functions using parametric features of 3ds MAX. You have five different types of function that help you to arrange objects in 3D space or even transform them along the array by modifying properties of the objects. To explain the functions of Parametric Array I have started to make a blog that contains more than 150 minutes video tutorials in three stages (basics, intermediate and advanced). You will find any information you need including documentations, FAQ and provided sample scenes. If you have any question regarding to this tool please feel free to comment on comment section.

The usual parametric source configuration simply consists of a directional transducer (often a plane piston or planar array) driven at two frequencies near the transducer resonance, forming a dual-frequency sound beam called the primary beam. Because sound-wave propagation is not a completely linear process, signals at new frequencies are formed effectively through the interaction of sound with sound as the beam progresses and are generated along the length of the primary beam. The lowest of these new frequencies is the difference of the two primary frequencies, and so the primary beam acts as an end-fire array of sources at the difference frequency. The effective length of the array will be determined by the attenuation of the primary beam, which occurs either as a result of small-signal absorption or, for sufficiently high primary amplitudes, as a result of nonlinear losses due to the generation of harmonics of the primary frequencies and other intermodulation components, such as the sum-frequency component. Most applications of parametric sources have been to underwater acoustics, but their use in air, as well as in other media, may be expected. Because the effective length of a parametric source can be made quite long in practice, it is possible to generate highly directional difference-frequency beams, and because the primary amplitude is shaded very gradually along the length of the array, these beams can be made practically side-lobe-free, in contrast to the beams from conventional acoustic sources.
As a result, echoes from a parametric source exhibit practically no reverberation, whereas conventional echoes may be obscured by reverberation from reflection of the side lobes. Thus, the parametric source may be expected to be useful in reverberation-limited situations where one desires a narrow beam from a small projector. Such applications include precision fathometry, subbottom profiling, echo ranging, communications, and Doppler navigation logs. In order to obtain the advantages of a parametric source, however, one must be willing to tolerate low efficiency and low search rate.
