Detailed Description

Computes bounding boxes of objects.

Bounding box can be computed for the following types of objects:

• entire model;
• graph element (and its subtree) - assembly, part or instance;
• part representation;
• B-Rep shape (ModelData::Shape);
• Mesh shape (ModelData::MeshShape);

A bounding box of a model is accumulation of bounding boxes of its roots.

A bounding box of an assembly is a cumulative bounding box of its children taking into account their transformation matrices.

A part's bounding box is accumulation of bounding boxes of available part's representations.

static

Computes an axis-aligned bounding box (AABB) of the mesh shape.

Compute() [3/5]

void cadex::Measurements::BoundingBox::Compute ( const ModelData::Model & theModel, ModelData::Box & theBox )

static

Computes an axis-aligned bounding box (AABB) of the model.

Compute() [4/5]

void cadex::Measurements::BoundingBox::Compute ( const ModelData::ModelElement & theElement, ModelData::Box & theBox )

static

Computes an axis-aligned bounding box (AABB) of the model element.

Compute() [5/5]

void cadex::Measurements::BoundingBox::Compute ( const ModelData::Shape & theShape, const Geom::Transformation & theTransformation, ModelData::Box & theBox )

static

Computes an axis-aligned bounding box (AABB) of the transformed shape.

ComputeMin() [1/2]

void cadex::Measurements::BoundingBox::ComputeMin ( const ModelData::Shape & theShape, const Geom::Transformation & theTransformation, ModelData::Box & theBox, Geom::Transformation & theOutTransformation )

static

Computes an oriented bounding box (OBB) of the transformed shape.

theTransformation is the input transformation applied to the shape before computing the bounding box.

theOutTransformation specifies the translation and rotation needed to place the input object inside the returned axis-aligned box.

Note

This API is currently in feature preview state and may change.

ComputeMin() [2/2]

void cadex::Measurements::BoundingBox::ComputeMin ( const ModelData::Shape & theShape, ModelData::Box & theBox, Geom::Transformation & theOutTransformation )

static

Computes an oriented bounding box (OBB) of the shape.

The method estimates the box orientation from the principal axes of inertia. Since ModelData::Box stores an axis-aligned bounding box (AABB), the computed orientation is returned as theOutTransformation.

theOutTransformation specifies the translation and rotation needed to place the input object inside the returned axis-aligned box.

Note

This API is currently in feature preview state and may change.

ComputeOptimal() [1/5]

void cadex::Measurements::BoundingBox::ComputeOptimal ( const ModelData::Body & theBody, ModelData::Box & theBox, Geom::Transformation & theOutTransformation )

static

Computes an optimal oriented bounding box (OBB) of the body.

The method attemps to determinate the box orientation from the planar faces and linear edges, and falls back to ComputeMin() if no suitable orientation is found.

theOutTransformation specifies the translation and rotation needed to place the input object inside the returned axis-aligned box.

ComputeOptimal() [2/5]

void cadex::Measurements::BoundingBox::ComputeOptimal ( const ModelData::MeshShape & theMeshShape, ModelData::Box & theBox, Geom::Transformation & theOutTransformation )

static

Computes an optimal oriented bounding box (OBB) of the mesh shape.

Note

For mesh shapes, this method curently returns an axis-aligned bounding box (AABB), and theOutTransformation is the identity transformation.
