LandClasses

LandClasses are regions specified by the LandControl PQSMod that can locally customize several features of the PQS, including features from other PQSMods like HeightColorMap or noise PQSMods. LandClasses can change terrain height, change terrain color, add color noise and height noise, and add ground scatters. LandClasses are defined via ranges of altitude, latitude, and longitude.

Subnodes #

• LerpRange = Defines range values
• Scatters = Defines used scatter amounts

Property	Format	Description
name	Text	The name of the LandClass.
alterApparentHeight	Decimal	Supposedly adjusts the terrain's appearance. Only ever observed in the practice of forming icecaps.
alterRealHeight	Decimal	Supposedly adjusts the terrain's actual height.
minimumRealHeight	Decimal	The minimum height of the LandClass's terrain.
color	Color	The color of the region.
coverageBlend	Decimal	The blend of the coverage with surrounding LandClasses.
coverageFrequency	Decimal	The size of the each feature of the LandClass coverage. As frequency gets bigger, size gets smaller.
coverageOctaves	Integer	The amount of blanketing over the LandClass coverage. Higher octaves mean rougher coverage.
coveragePersistance	Decimal	The complexity of or amount of detail in the LandClass coverage.
coverageSeed	Integer	The random seed of the LandClass coverage.
noiseBlend	Decimal	The blend of the LandClass noise with adjacent terrain.
noiseFrequency	Decimal	The size of the each feature of the LandClass noise. As frequency gets bigger, size gets smaller.
noiseOctaves	Integer	The amount of blanketing over the LandClass noise. Higher octaves mean rougher noise.
noisePersistance	Decimal	The complexity of or amount of detail in the LandClass noise.
noiseSeed	Integer	The random seed of the LandClass noise.
noiseColor	Color	The main color of the noise to be added to the LandClass.
latDelta	Decimal	The change between min and max of the latitude specified. 0 latitude?
latitudeDouble	Boolean	Whether to use a second latitude range - could be used for mirroring over the equator.
lonDelta	Decimal	The change between min and max of the longitude specified. 0 longitude?
altitudeRange	LerpRange	Determines the heights at which the LandClass encompasses.
latitudeRange	LerpRange	Determines the latitudes at which the LandClass encompasses.
latitudeFloatRange	LerpRange	Determines the second latitudes at which the LandClass encompasses - only used if latitudeFloat is true.
longitudeRange	LerpRange	Determines the longitudes at which the LandClass encompasses.

LerpRange #

Each LerpRange { } node describes a range of numbers to encompass, or lerp over. These ranges are applied to each dimension. The image below describes the valid ranges for latitude and longitude, with a handy diagram at the bottom for a visual description of the coverage of the LandClass over a Float "dimension." Areas where coverage is not complete are determined by the coverage___ properties.

Property	Format	Description
startStart	Decimal	The true start of the LandClass coverage. Coverage before this point is non-existent, while coverage after this point is sparse.
startEnd	Decimal	The end of the starting area of the LandClass coverage. Coverage before this point is sparse, while coverage after this point is complete.
endStart	Decimal	The start of the ending area of the LandClass coverage. Coverage before this point is complete, while coverage after this point is sparse.
endEnd	Decimal	The true end of the LandClass coverage. Coverage before this point is sparse, while coverage after this point is non-existent.

Scatters #

Although not a true scatters node, the Scatters { } node in a LandClass node has a list of values in which each modifies the density of the scatter's use in the LandClass.

Property	Format	Description
density	Decimal	The amount to modify the scatter's density with. Seems to be multiplied with the scatter's maxScatter?
scatterName	Text	The name of the scatter to modify the density of.
