Member Function Documentation
| virtual void iShadowBlock::AddAllShadows | ( | iShadowBlockList * | source | ) |  [pure virtual] | 
Copy all shadow frustums from another shadow block list into this block.
The frustums are not really copied but a new reference is kept.
| virtual void iShadowBlock::AddRelevantShadows | ( | iShadowBlockList * | source | ) |  [pure virtual] | 
Copy all relevant shadow frustums from another shadow block list into this block.
The frustums are not really copied but a new reference is kept.
| virtual void iShadowBlock::AddRelevantShadows | ( | iShadowBlock * | source, | |
| csTransform * | trans = 0 | |||
| ) |  [pure virtual] | 
Copy all relevant shadow frustums from another shadow block into this block.
The frustums are not really copied but a new reference is kept. However, if a transformation is given then a copy is made and the shadows are transformed.
| virtual csFrustum* iShadowBlock::AddShadow | ( | const csVector3 & | origin, | |
| void * | userData, | |||
| int | num_verts, | |||
| csPlane3 & | backplane | |||
| ) |  [pure virtual] | 
Add a new frustum and return a reference.
The frustum will have the specified number of vertices but the vertices still need to be initialized.
| virtual void iShadowBlock::AddUniqueRelevantShadows | ( | iShadowBlockList * | source | ) |  [pure virtual] | 
Add unique shadows.
Only add relevant shadow frustums that are not already in the current list. The frustums are not really copied but a new reference is kept.
| virtual void iShadowBlock::DeleteShadows | ( | ) |  [pure virtual] | 
Dereference all shadows in the list.
| virtual const csBox3& iShadowBlock::GetBoundingBox | ( | ) |  [pure virtual] | 
Get the bounding box of this shadow block.
| virtual csFrustum* iShadowBlock::GetShadow | ( | int | idx | ) |  [pure virtual] | 
Get the specified shadow.
| virtual int iShadowBlock::GetShadowCount | ( | ) |  [pure virtual] | 
Get the number of shadows in this list.
| virtual iShadowIterator* iShadowBlock::GetShadowIterator | ( | bool | reverse = false | ) |  [pure virtual] | 
Get an iterator to iterate over all shadows in this block.
| virtual void iShadowBlock::Transform | ( | csTransform * | trans | ) |  [pure virtual] | 
Apply a transformation to all frustums in this list.
| virtual void iShadowBlock::UnlinkShadow | ( | int | idx | ) |  [pure virtual] | 
Unlink a shadow frustum from the list and dereference it.
