Some formatting inconsistencies

[tsoj]

when converting from .obj to .dat vertex data will in some cases be formatted as [float][space][float][space][float]:

oolite-mesh-converters/Obj2DatTexNorm.py

Line 177 in d5156dc

return '%s %s %s' % (format_number(x), format_number(y), format_number(z))

But the Dat2ObjTex converter assumes that the vertices are separated by commas:

oolite-mesh-converters/Dat2ObjTex.py

Line 79 in d5156dc

coordinates = string.split(line, ',') # split line by commas

Also, it assumes that all float values that describe a face are separated by commas:

oolite-mesh-converters/Dat2ObjTex.py

Line 89 in d5156dc

tokens = string.split(line, ',') # split line by commas

It seems to make more sense to have code like this instead:

# ...
elif (mode == 'FACES'): 
   tokens = string.split(line, '\t')   # split line by tabs
   if (len(tokens) > 3) : 
   	color_data = string.split(tokens[0], ' ')
   	normal_data = string.split(tokens[1], ' ')
   	n_points = tokens[2]
   	point_data = string.split(tokens[3], ' ')
# ...
