Grids

OpenVDB can contain multiple grids which represent different «layers» of volume. The List View 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.

Sequence

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

Quadros

Number of frames of the sequence to use.

Início

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

Deslocamento

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

Mode

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

Clip:

Hides frames outside the specified frame range.

Extend:

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

Repetir:

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

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.

Nenhum:

The volume is not displayed in wireframe mode.

Contornos:

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

Boxes:

Displays a bounding boxes for nodes in the volume tree.

Pontos:

Displays points for nodes in the volume tree.

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.

Density

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

Interpolation

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

Linear:

Linear interpolation between voxels. Gives good smoothness and speed.

Cubic:

Cubic interpolation between voxels. Gives smoothed high quality interpolation, but is slower.

Mais próximo:

No interpolation between voxels. Gives raw voxels.

Slice

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

Eixos

Automático:

Adjust slice direction according to the view direction.

X/Y/Z:

Slice along the X, Y, or Z axis.

Posição

Position of the slice relative to the length of the respective domain side.

Render

Espaço

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

Objeto:

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

Ambiente:

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.

Completo:

Full float (Use 32 bit for all data).

Metade:

Half float (Use 16 bit for all data).

Variable:

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