mattcox / pmodel_selectOdd.cpp
Last active August 26, 2021 14:27
Example of a simple selection operation for the Modo procedural modelling system that selects every other polygon. It demonstrates how to use thread slots, to allow selection to be evaluated from multiple threads

mattcox / pmodel_createPlane_incremental.cpp
Last active July 30, 2022 20:27
Demonstrates a simple plane mesh operation for the Modo procedural modelling system. This demonstrates how to do incremental updates that create the polygon on the first evaluation, and then updates point positions on subsequent evaluations. Incremental updates can significantly improve performance, as Modo will only rebuild the surface for draw…

A pointless command that demonstrates how to use a notifier without arguments

mattcox / getInstance.cpp
Last active July 12, 2018 21:10
Demonstrates how to get a PackageInstance from a ILxItem COM interface. If you pass this function an item, it will return the class that it derives from, as long as it is one of your classes. Obviously, change the class name to whatever your class is called, as well as the server name!

getInstance (
ILxUnknownID item)
{
CLxLoc_PackageInstance pkgInstance (item);
CLxSpawner <Instance> spawn ("myInstance");
if (pkgInstance.test ())
return spawn.Cast (pkgInstance);

This sample plugin demonstrates how to create a very simple and pointless modifier. The modifier attaches to every light in the scene and sets the light radiance value to the distance from the center of the world.

Packages are features that can be added to a modo item to add channels and extend functionality. This may be to override drawing, add extra transforms, or provide some complex functionality that was beyond the capabilities of the original item. This sample demonstrates testing an item to see which packages it has.
import lx
hstSvc = lx.service.Host ()
hstSvc.SpawnForTagsOnly ()
allPackages = []
containsPackages = []
for i in range (hstSvc.NumServers (lx.symbol.a_PACKAGE)):
factory = hstSvc.ServerByIndex (lx.symbol.a_PACKAGE, i)

This python plugin example defines a new package that can be added to an existing item, adding a string channel called "customData".

This plugin example adds a new package that can be added to
an existing item, adding a float channel called "customData".
Essentially, it's just implementing a custom item. But by not
specifying a supertype, it becomes a generic item that can be
added to an existing item to extend their functionality.

Last active June 17, 2018 20:48
Demonstrates how to write an executable and queryable command. The difference is that this command will listen for state changes in a scene. If the selection changes, then the command will check its enable/disable state and force any form it's embedded into to update.
