# Module pyopenvdb

Classes | [hide private]
| Axis
| BoolGrid OpenVDB grid with voxels of type bool
| FloatGrid OpenVDB grid with voxels of type float
| GridClass Classes of volumetric data (level set, fog volume, etc.)
| Metadata Class that holds the value of a single item of metadata of a type for which no Python equivalent exists (typically a custom type)
| Transform
| Vec3SGrid OpenVDB grid with voxels of type vec3s
| VectorType The type of a vector determines how transforms are applied to it.

Functions | [hide private]
Transform |
createFrustumTransform(xyzMin, xyzMax, taper, depth, voxelSize) Create a new frustum transform with unit bounding box (xyzMin, xyzMax) and the given taper, depth and uniform voxel size. |
FloatGrid |
createLevelSetSphere(radius, center, voxelSize, halfWidth) Return a grid containing a narrow-band level set representation of a sphere. |
Transform |
createLinearTransform(matrix) Create a new linear transform from a 4 x 4 matrix given as a sequence of the form [[a, b, c, d], [e, f, g, h], [i, j, k, l], [m, n, o, p]], where [m, n, o, p] is the translation component. |
Grid |
read(filename, gridname) Read a single grid from a .vdb file. |
list, dict |
readAll(filename) Read a .vdb file and return a list of grids and a dict of file-level metadata. |
list |
readAllGridMetadata(filename) Read a .vdb file and return a list of grids populated with their metadata and transforms, but not their trees. |
Grid |
readGridMetadata(filename, gridname) Read a single grid's metadata and transform (but not its tree) from a .vdb file. |
dict |
readMetadata(filename) Read file-level metadata from a .vdb file. |
write(filename, grids, metadata=None) Write a grid or a sequence of grids and, optionally, a dict of (name, value) metadata pairs to a .vdb file. |
