Hello, having found that VRML supports macros, a suggestion comes into mind for VRML export of scenes containing CPK data. First, materials are unnecesarily redefined with every single object. Second, since atoms have no individuality, and spheres of each element the same size and material, any sphere can be a macro.
Use case: I have hand-optimized an exported VRML file, with a 35 per cent size reduction: PDB 5ACN without HOH exported: 3,535,096 bytes Same using DEF and USE: 2,340,799 bytes There is further capacity for optimisation by discretising cylinder joint lengths. If opaqueness is a condition, cylinders could be made in only a few sizes and 'shoved' into spheres if too long.
