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…

matchXfrm.cpp
Sample plugin to demonstrate a simple command that matches
position, rotation and scale between multiple selected items.
This command operates slightly differently to the built in
match.position, rotation, scale commands. The built in commands
will average out the transform if multiple items are selected,

mattcox / SurfaceForce.py
Last active December 16, 2021 14:48
This example plugin for modo 701, shows how to create a surface force in Python. The force will read a mesh, get the closest position on that mesh and find the normal at that position. A force will be created along the normal vector of the surface. The result is a force that pushes particles and dynamic objects away from the surface.

Python example demonstrating how to modify GL drawing of an item.
View shapeDraw.py
#python
'''
Shape Draw python example. This python plugins demonstrates how to create
a Package that can be added to existing items, that controls how they draw
in the GL viewport. We will simply draw a circle. A radius channel and an
sides channel will control how the circle is drawn.
To use, add the python script to an lxserv folder in your scripts directory.
Select an locator item and enter: item.addPackage shape.draw. To remove the

Created February 15, 2019 15:27
Demonstrates how to implement a custom Polymorph object that implements the SetCOM method. When the COM object is allocated, the SetCOM method will be passed a copy of the object, which can be useful if the allocated object needs passing to additional methods from within the COM implementation. Note: As the COM object is maintaining a pointer to…
