Class: vertextype

For usercreated meshes it is necessary to specify what vertextype you want to have. Different vertextypes have different attributes and sizes.

colortype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
memsize (vertextype): returns: (int bytes)
returns size in bytes.
memtocolor (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtonormal (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtopos (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtotangent (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtotex0 (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtotex1 (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtotex2 (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtotex3 (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
memtouser (vertextype): returns: ([int bytes])
returns byte offset from start of the vertex to this component. Returns nil if component not part of vertex.
normaltype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
postype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
tangenttype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
textype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
usertype (vertextype): returns: ([scalartype])
returns scalartype of the attribute or nil if not found.
vertex16color (): returns: (vertextype)
size 16 bytes, position (3 floats), color (4 unsigned byte).
vertex32normals (): returns: (vertextype)
size 32 bytes, normals (3 shorts), position (3 floats), color (4 unsigned bytes), 1 texcoord channel (2 floats).
vertex32texcoords (): returns: (vertextype)
size 32 bytes, position (3 floats), color (4 unsigned byte), 2 texcoord channels (2*2 floats).
vertex64 (): returns: (vertextype)
size 64 bytes, normals (3 shorts), position (3 floats), color (4 unsigned bytes), 4 texcoord channels (4*2 floats), tangents (4 shorts). The last 2 texcoord channels serve as user4 (4 floats) which may be used for hardware skinning.
