Detailed Description

Triangulation on float data.

Triangulation represents a set of triangular and quadrangular plates which are joined to each other by their common sides.
The triangulation consists of a sets of points, normals, surface parameters and a sets of triangles and quadrangles. The triangle is represented as three indices from the set of points defining vertices of triangle, the quadrangle is represented as four indices from the set of points defining vertices of quadrangle.

Member Function Documentation

◆ Clone()

SPtr<MbPrimitive> MbFloatGrid::Clone ( MbRegDuplicate * iReg = nullptr ) const

overridevirtual

Create a copy of primitive.

Create a copy of primitive using the registrator. Registrator is used for preventing multiple copying of primitive contained in several simultaneously copied objects. It is allowed not to use the registrator while copying a single object or a set of disconnected objects. The registrator must be used to copy several correlated objects successively. Correlation is an existence of references to common primitives in objects. Then, while copying without using the registrator, one can get a set of copies which contains references to the different copies of a single included primitive, what leads to loss of connection between the copies.

Parameters

[in] iReg - Registrator.

Returns: The object copy.

Implements MbPrimitive.

◆ Transform()

void MbFloatGrid::Transform ( const MbMatrix3D & matr )

overridevirtual

Transform primitive according to the matrix.

Transform primitive according to the matrix using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to transformation.

Parameters

[in] matr - A transformation matrix.

Implements MbPrimitive.

◆ Move()

void MbFloatGrid::Move ( const MbVector3D & to )

overridevirtual

Move primitive along a vector.

Move primitive along the vector using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to moving.

Parameters

[in] to - Movement vector.

Implements MbPrimitive.

◆ Rotate()

void MbFloatGrid::Rotate	(	const MbAxis3D &	axis,
		double	angle
	)

overridevirtual

Rotate primitive about an axis by a given angle.

Rotate primitive about an axis by a given angle using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to rotation.

Parameters

[in]	axis	- The rotation axis.
[in]	angle	- The rotation angle.

Implements MbPrimitive.

◆ AddColor()

void MbFloatGrid::AddColor	(	float	r,
		float	g,
		float	b,
		float	a
	)

overridevirtual

Add color as an additional information of point (0 <= r,g,b,a <= 1).

Warning: Values of color components should belong to the range [ 0; 1 ].

Implements MbGrid.

◆ GetLocation()

MbeItemLocation MbFloatGrid::GetLocation	(	const MbPlacement3D &	pl,
		double	eps,
		bool	onlyInItem = `false`
	)		const

overridevirtual

Define the object position relative to the plane.

Determine the object position relative to the XY-plane of a local coordinate system.

Parameters

[in]	pl	- A local coordinate system which defines a plane.
[in]	eps	- A metric tolerance.
[in]	onlyInItem	- Whether the object position relative to the XY-plane of a local coordinate system is interested only.

Returns: Iloc_OnItem - object intersects the XY plane of a local coordinate system,
iloc_InItem - object is located over the XY plane of a local coordinate system,
iloc_OutOfItem - object is located under the XY plane of a local coordinate system.

Implements MbGrid.

◆ InsideLocation()

bool MbFloatGrid::InsideLocation	(	const MbPlacement3D &	place,
		MbRect &	rect,
		double	eps
	)		const

overridevirtual
