[ICE] Converting integers to strings


Thanks to Mootzoid emTools, it’s easy to convert an integer to a string:
int2str_emtools
Note that you get padding too, so it’s easy to do things like generating replacements for the [Frame] token.
int2str_emtools_ntoa
The emTools string compounds are convenience compounds:
int2str_emtools_ntoa

For fun, I tried to create my own integer-to-string converter using the stock nodes. I did by dividing by 10 until the quotient (the result) was zero; with each division, I take the remainder and stick it at the front of the string. And by setting Max Repeat to 4, I get padding on my strings (so for integer 45 I get “0045”).
int2str_intdiv
Note the use of Delay Set Data. The integer division compound uses Modulo and Division by Scalar. The 2char compound simply uses a Select Case to map a single digit to a string:
int2str_2char

It did occur to me that I could do it all with a single Select Case šŸ™‚
int2str_selectcase
The catch is that the Select Case node has ten thousand cases.
int2str_selectcase_ppg
That’s really slow when you create that node in an ICE tree (for example, by importing a compound that uses it). It also takes a long time to create ten thousand cases, even with a script.

case_node = Application.AddICENode("$XSI_DSPRESETS\\ICENodes\\SelectCaseNode.Preset", "pointcloud1.pointcloud.ICETree")
string_node = Application.AddICENode("$XSI_DSPRESETS\\ICENodes\\StringNode.Preset", "pointcloud1.pointcloud.ICETree")

Application.ConnectICENodes("{0}.case0".format( case_node.FullName ), "{0}.result".format( string_node.FullName ) )
Application.DeleteObj( string_node.FullName )
Application.SetValue("{0}.case{1}_string".format( case_node.FullName, 0), "{0:0>4}".format(0), "")
Application.SetValue("{0}.default_string".format( case_node.FullName, "9999", "")

for i in range(1,10000):
	Application.AddPortToICENode("{0}.case{1}".format( case_node.FullName, i-1), "siNodePortDataInsertionLocationAfter")
	Application.SetValue("{0}.case{1}_string".format( case_node.FullName, i), "{0:0>4}".format(i), "")
