Extension Mesh Generation

Major extensions of functionality for mesh generation.

New Features

• [core]:
  • Added math::findPerpendicularVector() method to find a vector which is perpendicular to the given vector (optimized for speed and numerical stability)
• [geometry]:
  • Added classes CylindricalCoordinates and SphericalCoordinates for an efficient representation of cylindrical/spherical coordinates and their first order derivatives
  • CGMeshFactory: added following methods:
    • createCircleSlice, createCircleSector, createCircle
    • createCylinderSlice, createCylinderSector, createCylinder
    • createSphereSlice, createSphere
    • createCone
    • extrudeOutlineAlong3DPath, createCylindrical3DPath
  • SSVPointElement, SSVLineElement, SSVTriangleElement, SSVSegment: added method createMesh to generate a triangulated representation of the element/segment

Non-Breaking Changes

• [geometry]:
  • SSVElement, SSVPointElement, SSVLineElement, SSVTriangleElement: removed virtual keyword in front of virtual methods since this inherits from the base class anyway (allows to remove virtual destructor)
• [examples]:
  • added broccoli dependencies (eigen, sdl, zlib) for examples (such that examples can be compiled stand-alone without the unit-tests)
