Grids

OpenVDB can contain multiple grids which represent different «layers» of volume. The Поле «список» shows all the grids in the OpenVDB-file along with its name and data type.

OpenVDB File

File Path

Volume sample file used by the volume data-block.

Секвенция

Loads the OpenVDB-file as an animation loading separate files for individual frames.

Кадры (frames)

Number of frames of the sequence to use.

Начало (start)

Global starting frame of the sequence, assuming the first frame has a 1 in the file name.

Смещение (offset)

Offset the number of the frame to use in the animation.

Режим (mode)

Animation setting of the volume sequence before the start frame and after the end frame.

Обрезать (clip):

Hides frames outside the specified frame range.

Расширить (extend):

Repeats the start frame before, and the end frame after the frame range.

Повторять (repeat):

Cycles the frames in the sequence; restarting at frame one.

Ping-Pong:

Repeats the frames, reversing the playback direction on every other cycle.

Отображение во вьюпорте (viewport display)

Каркас (wireframe)

Method used to represent volumes in wireframe shading mode. For heavy volume data sets, it can be useful to set the object to always display as wireframe. This way the 3D Viewport remains responsive but the volume still appears in the final render.

Нет (none):

The volume is not displayed in wireframe mode.

Границы (bounds):

Displays the volume as Bounding Box for the entire volume grid.

Boxes:

Displays a bounding boxes for nodes in the volume tree.

Точки (points):

Displays points for nodes in the volume tree.

Детальность (detail)

The amount of detail to display for Boxes or Points wireframe mode.

Coarse:

Display one box or point for each intermediate tree node.

Fine:

Display a box or point for each leaf node containing 8×8 voxels.

Плотность (density)

Thickness of the volume in the 3D Viewport. The density of the volume in the render is adjusted via Volume Shading.

Интерполяция (interpolation)

Метод интерполяции, используемый для визуализации сетки флюида.

Линейно (linear):

Линейная интерполяция между вокселями. Обеспечивает хорошую скорость и плавность.

Кубический(-ая) (cubic):

Кубическая интерполяция между вокселями. Даёт сглаженную интерполяцию высокого качества, но работает медленнее.

Ближайшая (closest):

Никакой интерполяции между вокселями. Даёт необработанные воксели.

Разрезать (slice)

Рендер только одной 2D-секции объекта-домена.

Ось (axis)

Авто (auto):

Отрегулировать направление среза в соответствии с направлением вида.

X/Y/Z:

Slice along the X, Y, or Z axis.

Положение (position)

Расположение среза относительно длины соответствующей стороны домена.

Рендеринг (render)

Пространство (space)

Specifies how volume density and step size are computed relative either to the object or world.

Объект (object):

Keeps volume Density and Detail the same regardless of object scale.

Мир (world):

Specify Step Size and Density in world space.

Step Size Cycles Only

Distance between volume samples. Lower values render more detail at the cost of performance. If set to zero, the step size is automatically determined based on voxel size.

Clipping Cycles Only

Value under which voxels are considered empty space to optimize rendering.

Precision Cycles Only

Specifies volume data precision, lower values reduce memory consumption at the cost of detail.

Полностью (full):

Full float (Use 32 bit for all data).

Наполовину (half):

Half float (Use 16 bit for all data).

Variable:

Automatically vary the precision and use less precision for less noticeable areas.
