PVANodes ▸ Generators ▸ Reader
Read
Reads data from a reader into a grid, array or stack: the whole file, an index window, a value window or interpolated points. The lps input for interpolated points appears while method is points.
Inputs
| Port | Accepts | Required | Description |
|---|---|---|---|
reader | generator(reader) | required | The reader (HDF, table, geometry file, or directory set) that supplies the data |
lps | primitive(array) dataset(stack) dataset(grid) dataset(surface) | optional, quiet: shown when relevant, connected or pinned | Points to sample at (method = points); the output keeps this payload's shape |
Parameter ports
Added from the Parameters pane (⊕). While connected, each drives its parameter.
| Port | Accepts | Mode | Description |
|---|---|---|---|
r_index | primitive(array) | opt-in drives r_index | Drives the r window (index) parameter while connected |
t_index | primitive(array) | opt-in drives t_index | Drives the theta window (index) parameter while connected |
p_index | primitive(array) | opt-in drives p_index | Drives the phi window (index) parameter while connected |
r | primitive(array) | opt-in drives r | Drives the r window (value) parameter while connected |
t | primitive(array) | opt-in drives t | Drives the theta window (value) parameter while connected |
p | primitive(array) | opt-in drives p | Drives the phi window (value) parameter while connected |
Outputs
