Detailed Description

Represents a grid geometry drawn along the XY plane. If vertical cell count is specified then the grid becomes 3D.

Constructor & Destructor Documentation

~Grid()

virtual ~Grid ( )

inlinevirtual

Destructor.

Member Function Documentation

CellCount()

virtual unsigned int CellCount ( ) const

pure virtual

Get the number of cells on a planar grid.

Returns

Number of cells

Implemented in BaseGrid< T >.

CellLength()

virtual double CellLength ( ) const

pure virtual

Get the cell length.

Returns

The cell length

Implemented in BaseGrid< T >.

SetCellCount()

virtual void SetCellCount ( const unsigned int  _count )

pure virtual

Set the number of cells on a planar grid.

Parameters

[in]

_count

The number of cells

Implemented in BaseGrid< T >, BaseGrid< Ogre2Geometry >, and BaseGrid< OgreGeometry >.

SetCellLength()

virtual void SetCellLength ( const double  _len )

pure virtual

Set the cell length in one direction. The cells are assumed to be square.

Parameters

[in]

_len

The cell length

Implemented in BaseGrid< T >, BaseGrid< Ogre2Geometry >, and BaseGrid< OgreGeometry >.

SetVerticalCellCount()

virtual void SetVerticalCellCount ( const unsigned int  _count )

pure virtual

Set the vertical cell count of the grid. This makes the grid 3D.

Parameters

[in]

_count

Number of cells in vertical direction.

Implemented in BaseGrid< T >, BaseGrid< Ogre2Geometry >, and BaseGrid< OgreGeometry >.

VerticalCellCount()

virtual unsigned int VerticalCellCount ( ) const

pure virtual

Get the vertical cell count.

Returns

The vertical cell count.

Implemented in BaseGrid< T >.
