Transform Quantizer

by Duarte Ramos in Addons


Why can't I quantize mesh faces or edges?

Mesh edges are defined by the two connecting vertex. By quantizing both end vertex you end up quantizing the edges they define. Edges themselves don't really have a position property, unless you compute their median point, and quantizing that could potentially look arbitrary.
Guaranteeing one edge was quantized by moving its center would unintentionally alter the positions of all adjacent ones, leading to possible conflicts or undesired results.
Likewise faces could be even more complex since they are potentially non planar, and quantizing by their center could be hard since there are many ways to measure them (like median or center of mass) and centering those would become meaningless and hard to predict.
Ensuring multiple adjacent faces had a quantized center position would also be hard, since moving neighbours alters their shape, which in turn alters their centers again recursively, leading to a deadlock.

Why do my objects not lign up correctly to a grid?

Some objects are missing or overlapping, how can I fix them?


Quantizer only quantizes the position coordinates by rounding them to the closest matching value for the given precision threshold. If in your original scene or model they happen to be deviated enough from their "correct" or expected position, they may end up an undesirable or unexpected position.
The addon only does a purely mathematical rounding of values, it doesn't try to "be smart" about it. If you get "wrong" results those have most likely to be fixed manually, either before quantizing by manually moving the objects closer to their desired final position, or afterwards by snapping them into place.
Why can't I quantize vertex rotation or scale

Vertex or bezier curve control points are one dimensional by definition and don't really have rotation or scale values, so it is not possible to quantize these types of transforms for them.

Bezier curves do have a Radius property by vertex, but it is not supported at the the moment for quantization
