A mesh is a BZW map object that defines an arbitrary three dimensional shape. A mesh is defined as a series of faces containing 3 or more points in three dimensional space ( or a vertex ).

Code

The code for a mesh object is as follows, this is only an example

mesh
 name example_mesh
 # Material properties applied to a mesh apply to all faces
 # that follow the setting. Mesh faces will alter their own
 # properties without affecting the state of the mesh properties.
 # The same pattern is used to apply physics drivers.
 vertex 100 200 300  # add a vertex		 (repeatable)
   normals 2 6 0 4 7	# list of normals	       (optional)
   texcoords 0 3 2 4 9	# list of texture coordinates  (optional)
   phydrv example_phydrv  # assign a physics driver
 endface  # end the face
 #
 #  This next element can be added to increase the rendering speed
 #  of the mesh object. If the client is capable of using this data,
 #  then it is used to draw the mesh instead of the face  information.
 #
 drawInfo
   dlist		      # display list for all material sets
   decorative		      # older clients with not see this mesh
   angvel <degrees/sec>       # rotation about initial Z axis
   extents <minX> <minY> <minZ> <maxX> <maxY> <maxZ>
   sphere <x> <y> <z> <radiusSquared>
   corner <v> <n> <t>	      (repeatable)

       quadstrip 0 1 2 3      (repeatable)
       polygon	 0 1 2	      (repeatable)
     end  # matref
   end	  # lod
 end	  # drawInfo
end	  # mesh

TODO::add stuff here

Meshes have full support for Material, Texture Matrix, and Physics Drivers.

Appearance

The appearance of a mesh will vary greatly as by it's very nature it can be defined to look like anything.

Editor Support

The mesh object only supported by the BZWTools blender plugin.

History

The Mesh object was added with the v2.0.0 release of BZFlag.
