Properties – Властивості¶

Grids¶

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

OpenVDB File¶

File Path – Шлях Файлу: Volume sample file used by the volume data-block.

Sequence – Послідовність

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

Frames – Кадри: Number of frames of the sequence to use.

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

Offset – Зсув: Offset the number of the frame to use in the animation.

Mode – Режим

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

Clip – Кліп: Hides frames outside the specified frame range.
Extend – Розшир: Repeats the start frame before, and the end frame after the frame range.
Repeat – Повтор: Cycles the frames in the sequence; restarting at frame one.
Ping-Pong: Repeats the frames, reversing the playback direction on every other cycle.

Viewport Display – Показ Оглядвікна¶

Wireframe – Каркас

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.

None – Нема: The volume is not displayed in wireframe mode.
Межі – Bounds: Displays the volume as Bounding Box for the entire volume grid.
Boxes: Displays a bounding boxes for nodes in the volume tree.
Points – Точки: Displays points for nodes in the volume tree.

Детальність – 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.

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

Interpolation – Інтерполяція

Interpolation method to use for the visualization of the fluid grid.

Linear – Лінеарно: Linear interpolation between voxels. Gives good smoothness and speed.
Cubic – Кубічно: Cubic interpolation between voxels. Gives smoothed high quality interpolation, but is slower.
Closest – Найближче: No interpolation between voxels. Gives raw voxels.

Slice¶

Renders only a single 2D section of the domain object.

Axis – Вісь

Auto – Авто: Adjust slice direction according to the view direction.
X/Y/Z: Slice along the X/Y/Z axis.

Position – Позиція: Position of the slice relative to the length of the respective domain side.

Render – Рендер¶

Space – Простір

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

Object – Об’єкт: Keeps volume Density and Detail the same regardless of object scale.
World – Світ: 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.
