Member Function Documentation
virtual void iMeshGeneratorGeometry::AddDensityMaterialFactor | ( | iMaterialWrapper * | material, | |
float | factor | |||
) | [pure virtual] |
Add a density factor based on a material.
The base density will be used to try a number of positions in every cell. Then for that position it will determine the material that is hit. If that material is listed in the density factor table then that factor will be used to determine if the position should be used or not. Setting a factor of 0 here will disable the material. Setting a factor of 1 will give full density.
virtual void iMeshGeneratorGeometry::AddFactory | ( | iMeshFactoryWrapper * | factory, | |
float | maxdist | |||
) | [pure virtual] |
Add a factory and the maximum distance after which this factory will no longer be used.
The minimum distance will be calculated from the maximum distance used for other factories in this geometry.
virtual void iMeshGeneratorGeometry::AddPosition | ( | const csVector2 & | pos | ) | [pure virtual] |
Add position for placing mesh (only material factor will influence it).
virtual float iMeshGeneratorGeometry::GetDensity | ( | ) | const [pure virtual] |
Get the density.
virtual iMeshFactoryWrapper* iMeshGeneratorGeometry::GetFactory | ( | size_t | idx | ) | [pure virtual] |
Get a specified factory.
virtual size_t iMeshGeneratorGeometry::GetFactoryCount | ( | ) | const [pure virtual] |
Get the number of factories for this geometry.
virtual float iMeshGeneratorGeometry::GetMaximumDistance | ( | size_t | idx | ) | [pure virtual] |
Get a specified maximum distance.
virtual float iMeshGeneratorGeometry::GetRadius | ( | ) | const [pure virtual] |
Get the radius for this object.
virtual void iMeshGeneratorGeometry::RemoveFactory | ( | size_t | idx | ) | [pure virtual] |
Remove a factory.
virtual void iMeshGeneratorGeometry::SetDefaultDensityMaterialFactor | ( | float | factor | ) | [pure virtual] |
Set the default factor to use in case the material found on the meshes is not any of the ones defined in the material factory table.
By default the default factor is 0. This means that as soon as you use SetDensityMaterialFactor() above then on every material that is not listed there will be no foliage generated. The default factor is NOT used in case the material factor table is empty.
virtual void iMeshGeneratorGeometry::SetDensity | ( | float | density | ) | [pure virtual] |
Set the density.
The density is defined as the number of objects in every 1x1 square. Default density is 1.
- Todo:
- add density map support.
virtual void iMeshGeneratorGeometry::SetDensityMap | ( | iTerraFormer * | map, | |
float | factor, | |||
const csStringID & | type | |||
) | [pure virtual] |
Set a density map in grayscale with factor.
The base density will be used to try a number of positions in every cell. Density map will be used to affect base density at given point. So for given point density will be based on base density * value from density map * map factor.
virtual void iMeshGeneratorGeometry::SetRadius | ( | float | radius | ) | [pure virtual] |
Set the radius for this object.
No other objects will be generated within this radius. If this radius is 0 then there is no limitation on object generation (i.e. objects can be put on top of each other if the random generator decides to do that). Default is 0.
