Detailed Description

The basic interface for shapes. A shape is a kind of instanciable mesh. For simplicity, render() and clip() virtual method are provided, so majority of shape could be implemented by just define those methods, and let createInstance() as default. But other complex shapes may be defined, by implement a compatible model which will comunicate with them.

Serialisation of a shape MUST be done with ISTREAM::serialPolyPtr.

Member Function Documentation

virtual bool NL3D::IShape::clip (  const std::vector< CPlane > &  pyramid,
const CMatrix &  worldMatrix
)  [inline, virtual]
 

clip this shape with a pyramid. the pyramid is given in world space.The world matrix of the object is given.

Parameters:
pyramid the clipping polytope, planes are normalized.
worldMatrix the world matrix of the instance.
Returns:
true if the object is visible, false otherwise. The default behavior is to return true (never clipped).

Returns:
the specialized instance for this shape.

virtual IMeshGeom* NL3D::IShape::supportMeshBlockRendering (  CTransformShape *  trans,

return !NULL if this shape can support MeshBlock rendering for a special instance. NB: Mesh Block render cannot occurs if the Mesh is Skinned/MeshMorphed. NB: Mesh Block render can occurs only in Opaque pass NB: Mesh block render can occurs only for CMeshBase meshes.

Parameters:
trans the instance to take into account (meshMultiLod may return NULL in blend transition).
polygonCount the number of polygons to render for the meshGeom returned
Returns:
the meshgeom to render per block if OK, else NULL (default)
