Base Types

This section presents the fundamental types of Easy3D to represent objects in a 3D space.

E3DPoint

The object E3DPoint ^{.NET Python} represents points in a 3D space. An E3DPoint ^{.NET Python} is the basic container for data processing in a 3D space.

• A E3DPoint ^{.NET Python} is defined by its X, Y and Z coordinates.

• Use the function E3DPoint::DistanceTo ^{.NET Python} to compute distances between points

• You can combine points to form point clouds (see below).

E3DLine

The object E3DLine ^{.NET Python} represents lines in a 3D space.

• An E3DLine ^{.NET Python} is defined by two points.

E3DPlane

The object E3DPlane ^{.NET Python} represents planes in a 3D space.

• An E3DPlane ^{.NET Python} is defined by its normal vector and the signed distance to the origin of the axes.

• Use the function E3DPlane::DistanceTo ^{.NET Python} to compute the distance to any point.

• Use the function E3DPlane::ProjectPoint ^{.NET Python} to project points onto planes.

• Use the function E3DPlane::Transform ^{.NET Python} with transformation matrices to rotate and translate planes.

E3DSphere

The object E3DSphere ^{.NET Python} represents spheres in a 3D space.

• An E3DSphere ^{.NET Python} is defined by its center point and its radius.

• Use the function E3DSphere::DistanceTo ^{.NET Python} to compute the distance to any point.

• Use the function E3DSphere::Transform ^{.NET Python} with transformation matrices to rotate and translate spheres.

E3DBox

An E3DBox ^{.NET Python} is a rectangular parallelepiped in a 3D space. It can have any orientation and be centered on any point in the 3D space.

• An E3DBox ^{.NET Python} is defined by a center point, 3 axes and the extension of the box along each axis.

• Use the function E3DBox::Transform ^{.NET Python} with transformation matrices to rotate and translate boxes.

E3DObject

In eVision, an E3DObject ^{.NET Python} is a geometric representation of a set of 3D points.

• Use the E3DObject ^{.NET Python} to get the characteristics such as the extend along the 3 axes, the area, the total volume and the average position of the set of points.

• Use the function E3DObject::GetBasePlane ^{.NET Python} to get the fitted plane of the set of points.

• Use the function E3DObject::GetBoundingBox ^{.NET Python} to get the bounding box, represented by a E3DBox ^{.NET Python} enclosing the set of points.
