Detailed Description

Polygonyal surface. Each individual polygon is stored using the space sub-division for better performence.

Restrictions: 1) vertex(unsigned), vertex(unsigned, unsigned), vertex(unsigned, unsigned, unsigned) and vertexUV(unsigned, unsigned) methods of vertex definition are used with accord to existance of corresponding global arrays, i.e. vertices, vertices+normals, vertices+normals+uv_coords and vertices+uv_coords. 2) The done() method must be called at the end of surface definition. 3) normal() defines normal vector for the next polygon ONLY. 4) If normal vectors of surface facets are defined then they should be properly oriented (e.g. all directed outward a solid). 5) When using TRIANGLES or QUADS method of surface creation then edge loops of all facets must be oriented in the same way (preffered loop direction is counter-clockwise because clockwise loops creates facet normals directing towards a solid). 6) The array of vertices should contain only vertices really used by any facet because some operations like extent() works directly with this array.

Protocol: Surface s(...); [s.normal(x,y,z);] s.vertex(index1, index2); s.vertex(...); ... s.done();
