The first option, Rotate, will give you the option of rotating the structure about the viewing axes.

These axes are fixed in the window. When a rotation is applied, the structure rotates within this viewing axis, but its coordinates DO NOT CHANGE. The true X, Y, and Z axes are fixed to the structure and cannot be changed in this manner. For the purpose of display, Red corresponds to the X-axis, Green corresponds to the Y-axis, and Blue corresponds to the Z-axis. Again, this affects the viewing angle ONLY. Your structure will retain its original coordinates and added mass matrix.

The next two options, Light and Material, will change the color of the light shining on the object and of the material itself.

The sub-menu of View Structure will change the structure displayed.

Initially, only the default structure can be displayed, as it is the only one stored in the program itself. Later, as you input additional structures, you can toggle between them to view each one in turn. Click here to learn about reading files.

The final menu item with a sub-menu, View M_ij, will enable you to print out the calculated Added Mass Matricies of any structures that have been read into Amass.

At first, only the Default structure will have any non-zero M_ij entries, but after other data files are entered, their M_ij matricies will be stored in memory to be displayed later. (They are also displayed as the file is entered). The M_ij for any structure may be recalled individually, or all 6 may be displayed at once.

Read File will let you input a new structure. To learn how to do this, click here.

Alter File will let you translate a structure, and then output the altered datafile. This enables the creation of many similar, complicated structures without a lot of retyping on your part. To learn how to do this, click here.

Read Motion will let you enter a motion file which contains a series of runs varying velocity, angular velocity, and acceleration. Click here to learn about Motion Files.

Reset View will reset the viewing angle to the original position and the colors to white. All structures and M_ij's will be maintained.

Reset All will completely reset the entire program. It is effectively the same as quiting Amass and restarting.

Quit will exit Amass and return your xterm.
