Detailed Description

This class will mark vertices of a mesh, which are visible from far away (from outside).

Triangle is visible if each vertex of it is visible.

Constructor & Destructor Documentation

◆ LodOutsideMarker()

Ogre::LodOutsideMarker::LodOutsideMarker ( LodData::VertexList vertexList,
Real  boundingSphereRadius,
Real  walkAngle 
)
Parameters
vertexListList of vertices. vertex.position is the input and vertex.isOuterWallVertex is the output of the algorithm.
walkAngleWalk angle in dot product values. Allowed range is from -1 to 1. Default = 0. Smaller value is bigger angle. If you set it to 1 then you can disable walking and it will only mark the vertices on the convex hull.
