Member Data Documentation

bounds

Aabb superdex::GridSdfData::bounds

Spatial bounds of the SDF grid.

Values are distributed uniformly within this volume.

Definition at line 64 of file model_data.h.

dims

Int3 superdex::GridSdfData::dims {}

Dimensions of the SDF grid in X, Y, and Z.

Definition at line 54 of file model_data.h.

negativeValueBounds

Aabb superdex::GridSdfData::negativeValueBounds

Spatial bounds of the portion of the SDF grid with negative values.

Note

This is generally the bounds of the mesh for which the SDF grid was computed, while the overall grid bounds may be larger due to padding for penalty fall-off distance.

Definition at line 72 of file model_data.h.

rotation

std::optional<Quaternion> superdex::GridSdfData::rotation

Optional parent-from-grid rotation to apply at runtime.

Note

Applied order is scale, then rotation, then translation.

Typically set when a transform is baked into the containing model.

Definition at line 88 of file model_data.h.

scale

std::optional<Real3> superdex::GridSdfData::scale

Optional parent-from-grid per-axis scale to apply at runtime.

Note

Applied order is scale, then rotation, then translation.

Typically set when a transform is baked into the containing model.

Definition at line 80 of file model_data.h.

translation

std::optional<Real3> superdex::GridSdfData::translation

Optional parent-from-grid translation [m] to apply at runtime.

Note

Applied order is scale, then rotation, then translation.

Typically set when a transform is baked into the containing model.

Definition at line 96 of file model_data.h.

values

DynamicArray<real> superdex::GridSdfData::values

Signed distance values [m].

Note

Size must be (dims[0] * dims[1] * dims[2])
