Mesh serialize doubles its weight

[Dad72]

Hello,

Is it normal that after serializing is the double weight of a model not serialized.

I have a model with Skeleton and animation that 16 MB, but once serialize, the file is now 38 MB Why is not it the same weight. is there information duplicate add?

I think the difference is huge. it has 22 MB add to the original file 16MB

This is kind of expected as JSON serialization adds a lot of data when serializing numbers (instead of serializing "0", it will serialize "0.0000000")

[Dad72]

How can we remove it to reduce the final weight of the object to serialize?

I don't know

This is a pure JS question actually. And I'm not sure we can control how JS serializes data.

Perhaps something like that: https://github.com/tcorral/JSONC

Yet when I look in the file, the numbers have no 0.0000., I see 0.

By cons it is true that each number has a float number rise after the comma compare the original file.

4 decimal in the original file and 16 after the decimal point in the serialized file. (4 * 4)

There is no possibility to reduce the number of decimal 4 or 6 at the time of serialization in Babylon.

Thanks Adam.

var str_serialized = JSON.stringify(serialization, function(key, val) { return val.toFixed ? Number(val.toFixed(4)) : val;});

Arf, in fact if I made it, the model not load.

With PHP if I had done this instead of recording in gross, decreases the file is 26 MB rather that 38 MB I still fails to get closer to the initial weight of the file (before serialization 16 MB). There I  +10MB.

But the file babylon load after 

$json = json_decode($value, true);

$json["meshes"][0]["scaling"][0] = (float)$_POST['scale'];
$json["meshes"][0]["scaling"][1] = (float)$_POST['scale'];
$json["meshes"][0]["scaling"][2] = (float)$_POST['scale'];

$save = json_encode($json);

@chmod($root, 0777);
file_put_contents($root, $save);
