Member Function Documentation

CVisualCollisionEntity * NL3D::CVisualCollisionManager::createEntity (    ) 
 

create an entity.

NB: CVisualCollisionManager do not owns this ptr for now, and you must delete it with deleteEntity(). NB: CVisualCollisionEntity are no more valid when this manager is deleted.

void NL3D::CVisualCollisionManager::setLandscape (  CLandscape *    landscape ) 
 

setup the landscape used for this collision manager.

ptr is kept, and manager and all entities must be cleared when the landscape is deleted.

void NL3D::CVisualCollisionManager::setSunContributionPower (  float    power,
float    maxThreshold
) 
 

for CVisualCollisionEntity::getStaticLightSetup().

See also:
CVisualCollisionEntity::getStaticLightSetup()
Build a lighting table to remap sun contribution from landscape to sun contribution for objects. The value remap the landscape sun contribution (0 ~ 1) to an object sun contribution (0 ~1) using the following formula:

objectSunContribution = min ( powf ( landscapeSunContribution / maxThreshold, power ), 1 );

Default is 0.5 (=> sqrt) for power and 0.5 for maxThreshold.
