Nested Volume Modifier



Nested Volume modifier set other volume data inside the volume as nested data.
In some simulations, most part of the volume is quite uniform, while the some part has complex structure. Even if the important part of the data requires high resolution, it may be too expensive to use that resolution of the entire volume.
In these case, one may divide them to some pars, one with low resolution for wide range, and other with high resolution for narrow range.
You can nest the later one to the former one with this modifier.

With this modifier, the child data will be called by the parent data and drawn as single data.
Since not being drawn one by one, no artifact would be shown if each data is consistent ones.

MRI Head data nested in default data. Tough this is a bad sample, the function of this modifier is clearly shown.

Target

Target volume will be nested to the center of volume.
(Off-centered nest is not implemented yet.)
The original data in the nested region will be overriden by the target data.
The target volume data becomes invisible, to prevent from double writing.

Size

The size of nested grid.
If it is set to 0.5, the nested data will be set to the region [0.25 - 0.75].

Rim

Width of the rim.
The data would be interpolated linearly within the rim region.

Nest Type

Box and sphere can be selected for the shape of nesting.
Spherical nest is for data in spherical coordinates.

Repeated Nest

This modifier can be used repeatedly up to 4.
Thus, volume data like followings can be achieved.
Volume_D at the center of Volume_C, which is at the center of Volume_B, which is at the center of Volume_A.

Material Setting

Since child data is considered as a part of parent one, material setting of parent volume is used to draw both data.
Thus, material setting of child volume has no menings and ignored here.
