qft-infinite-sweep.mjs — workshop the cartesian grid as INFINITE
|
||
|
|
space: wide/deep/shallow slabs + camera pushed into the lattice +
|
||
|
|
exaggerated perspective, so the field bleeds off every edge and
|
||
|
|
rushes to a vanishing point rather than reading as a closed cube.
|
||
|
|
Usage: node tools/qft-infinite-sweep.mjs [size]
