java.lang.Objectcom.jme3.terrain.heightmap.AbstractHeightMap
public abstract class AbstractHeightMap
AbstractHeightMap
provides a base implementation of height
data for terrain rendering. The loading of the data is dependent on the
subclass. The abstract implementation provides a means to retrieve the height
data and to save it.
It is the general contract that any subclass provide a means of editing
required attributes and calling load
again to recreate a
heightfield with these new parameters.

public void unloadHeightMap()
unloadHeightMap
clears the data of the height map. This
insures it is ready for reloading.
HeightMap

public void setHeightScale(float scale)
setHeightScale
sets the scale of the height values.
Typically, the height is a little too extreme and should be scaled to a
smaller value (i.e. 0.25), to produce cleaner slopes.
HeightMap
内の setHeightScale
scale
- the scale to multiply height values by.public void setHeightAtPoint(float height, int x, int z)
setHeightAtPoint
sets the height value for a given
coordinate. It is recommended that the height value be within the 0 - 255
range.
HeightMap
内の setHeightAtPoint
height
- the new height for the coordinate.x
- the x (east/west) coordinate.z
- the z (north/south) coordinate.public void setSize(int size) throws java.lang.Exception
setSize
sets the size of the terrain where the area is
size x size.
HeightMap
内の setSize
size
- the new size of the terrain.
java.lang.Exception
JmeException
- if the size is less than or equal to zero.public void setMagnificationFilter(float filter) throws java.lang.Exception
setFilter
sets the erosion value for the filter. This
value must be between 0 and 1, where 0.2 - 0.4 produces arguably the best
results.
HeightMap
内の setMagnificationFilter
filter
- the erosion value.
java.lang.Exception
JmeException
- if filter is less than 0 or greater than 1.public float getTrueHeightAtPoint(int x, int z)
getTrueHeightAtPoint
returns the non-scaled value at the
point provided.
HeightMap
内の getTrueHeightAtPoint
x
- the x (east/west) coordinate.z
- the z (north/south) coordinate.
public float getScaledHeightAtPoint(int x, int z)
getScaledHeightAtPoint
returns the scaled value at the
point provided.
HeightMap
内の getScaledHeightAtPoint
x
- the x (east/west) coordinate.z
- the z (north/south) coordinate.
public float getInterpolatedHeight(float x, float z)
getInterpolatedHeight
returns the height of a point that
does not fall directly on the height posts.
HeightMap
内の getInterpolatedHeight
x
- the x coordinate of the point.z
- the y coordinate of the point.
public float[] getHeightMap()
getHeightMap
returns the entire grid of height data.
HeightMap
内の getHeightMap
public float[] getScaledHeightMap()
HeightMap
内の getScaledHeightMap
public int getSize()
getSize
returns the size of one side the height map. Where
the area of the height map is size x size.
HeightMap
内の getSize
public boolean save(java.lang.String filename) throws java.lang.Exception
save
will save the heightmap data into a new RAW file
denoted by the supplied filename.
filename
- the file name to save the current data as.
java.lang.Exception
JmeException
- if filename is null.public void normalizeTerrain(float value)
normalizeTerrain
takes the current terrain data and
converts it to values between 0 and value
.
value
- the value to normalize to.public float[] findMinMaxHeights()
public void erodeTerrain()
erodeTerrain
is a convenience method that applies the FIR
filter to a given height map. This simulates water errosion.
setFilter
public void flatten(byte flattening)
flattening
- the power of flattening applied, 1 means nonepublic void smooth(float np)
np
between 0 and 1
np
- The factor to what extend the neighbors average has an influence.
Value of 0 will ignore neighbors (no smoothing)
Value of 1 will ignore the node old height.
