Package: gp

Open Cascade documentation: gp.

This package provides the following:

• Pnt: defines a 3D cartesian point.

• Xyz: describes a cartesian coordinate entity in 3D space {X,Y,Z}. This entity is used for algebraic calculation. This entity can be transformed with a “Trsf” or a “GTrsf” from package “gp”. It is used in vectorial computations or for holding this type of information in data structures.

• Vec: defines a non-persistent vector in 3D space.

• gp_Ax2

• gp_Ax22d

• gp_Ax2d

• gp_Ax3

• gp_Circ

• gp_Circ2d

• gp_Cone

• gp_Cylinder

• gp_Dir

• gp_Dir2d

• gp_Elips

• gp_Elips2d

• gp_EulerSequence

• gp_GTrsf

• gp_GTrsf2d

• gp_Hypr

• gp_Hypr2d

• gp_Lin

• gp_Lin2d

• gp_Mat

• gp_Mat2d

• gp_Parab

• gp_Parab2d

• gp_Pln

• gp_Pnt2d

• gp_Quaternion

• gp_QuaternionNLerp

• gp_QuaternionSLerp

• gp_Sphere

• gp_Torus

• gp_Trsf

• gp_Trsf2d

• gp_TrsfForm

• gp_TrsfNLerp

• gp_Vec2d

• gp_Vec2f

• gp_Vec3f

• gp_VectorWithNullMagnitude

• gp_XY

Some “sugar” is added for this package:

1. You can mix floats and integers while defining the points.
2. You can assign values like pnt.x = 8 and get the value with: echo pnt.x
3. The same applies with: pnt[0] = 8 and echo pnt[0]
