public JDefaultHeightMap(JDefaultDataMap dataMap)

The constructor creates geometry and appearance height map.

Parameters:

dataMap - The data required to create a height map.

JDefaultHeightMap

public JDefaultHeightMap(JDefaultDataMap dataMap,
                         java.lang.String fileNameTexture)

The constructor creates geometry and appearance height map.

Parameters:

dataMap - The data required to create a height map.

fileNameTexture - Name of file with texture

Method Detail

createAppearance

public void createAppearance()

The method creates default appearance of the loaded map.

createAppearance

public void createAppearance(java.lang.String fileNameTexture,
                             JHeightMap.AbstractDataMap dataMap)

The method creates default appearance of the loaded map. The texture is used on the map.

Parameters:

fileNameTexture - Name of the file, where the texture is.

dataMap - Data loaded map

createGeometry

public void createGeometry(JHeightMap.AbstractDataMap map)

The method creates a geometry of the loaded map.

Parameters:

map - Data loaded map

resetMap

public void resetMap()

The method resets geometry map.

isWireModelMap

public boolean isWireModelMap()

The method detects whether a wire model is switch on or not

Returns:

The method returns "true" if the wire model is switch on, else the method returns "false".

isValidCoordinates

public boolean isValidCoordinates(int x,
                                  int y,
                                  int width,
                                  int height)

The method detects whether a point is on the map ore not.

Parameters:

x - Order point in the x-axis

y - Order point in the y-axis

width - width map

height - height map

Returns:

The method returns "true" if the point is on the map, else the method returns "false".

isMatrixZero

public boolean isMatrixZero(float[] matrix)

The method calculates whether filter matrix is zero

Parameters:

matrix - Filter matrix

Returns:

The method returns "true" if the filter matrix is zero, else the method returns "false".
