base class — bpy_struct

class bpy.types.VoxelData(bpy_struct)

Voxel data settings

domain_object

Object used as the smoke simulation domain

Type :Object
extension

Sets how the texture is extrapolated past its original bounds

  • EXTEND Extend, Extends by repeating edge pixels of the image.
  • CLIP Clip, Clips to image size and sets exterior pixels as transparent.
  • REPEAT Repeat, Causes the image to repeat horizontally and vertically.
Type :enum in [‘EXTEND’, ‘CLIP’, ‘REPEAT’], default ‘EXTEND’
file_format

Format of the source data set to render

  • BLENDER_VOXEL Blender Voxel, Default binary voxel file format.
  • RAW_8BIT 8 bit RAW, 8 bit greyscale binary data.
  • IMAGE_SEQUENCE Image Sequence, Generate voxels from a sequence of image slices.
  • SMOKE Smoke, Render voxels from a Blender smoke simulation.
Type :enum in [‘BLENDER_VOXEL’, ‘RAW_8BIT’, ‘IMAGE_SEQUENCE’, ‘SMOKE’], default ‘BLENDER_VOXEL’
filepath

The external source data file to use

Type :string, default “”
intensity

Multiplier for intensity values

Type :float in [0.01, inf], default 0.0
interpolation

Method to interpolate/smooth values between voxel cells

  • NEREASTNEIGHBOR Nearest Neighbor, No interpolation, fast but blocky and low quality.
  • TRILINEAR Linear, Good smoothness and speed.
  • QUADRATIC Quadratic, Mid-range quality and speed.
  • TRICUBIC_CATROM Cubic Catmull-Rom, High quality interpolation, but slower.
  • TRICUBIC_BSPLINE Cubic B-Spline, Smoothed high quality interpolation, but slower.
Type :enum in [‘NEREASTNEIGHBOR’, ‘TRILINEAR’, ‘QUADRATIC’, ‘TRICUBIC_CATROM’, ‘TRICUBIC_BSPLINE’], default ‘NEREASTNEIGHBOR’
resolution

Resolution of the voxel grid

Type :int array of 3 items in [1, 100000], default (0, 0, 0)
smoke_data_type

Simulation value to be used as a texture

  • SMOKEDENSITY Density, Use smoke density as texture data.
  • SMOKEHEAT Heat, Use smoke heat as texture data. Values from -2.0 to 2.0 are used.
  • SMOKEVEL Velocity, Use smoke velocity as texture data.
Type :enum in [‘SMOKEDENSITY’, ‘SMOKEHEAT’, ‘SMOKEVEL’], default ‘SMOKEDENSITY’
still_frame

The frame number to always use

Type :int in [-300000, 300000], default 0
use_still_frame

Always render a still frame from the voxel data sequence

Type :boolean, default False
