glu3D is a complete system that makes easy making liquids in Autodesk's 3dsMax, Maya and XSI. glu3D uses particles to simulate the liquid behavior, and a multi-resolution polygonal surface is also generated to display the liquid surface.

Its main features are:
Particle based dynamic engine that automatically animates liquids that interact with surrounding geometry
Poly surface mesh surface sequence is generated to visualize liquid surface
Fully integrated in 3dsMax and Maya
File cache system to store pre-calculated dynamics results
Wet maps ( 3dsMax only)
Texture mapping ( 3dsMax only)
Arbitrary planar shapes as sources ( 3dsMax only)
Fill objects function to speed up scene initial condition setup
Friendly customizable UI full of shortcuts, menus and toolbar buttons
Integration with Particle Flow ( 3dsMax only)

Pwrapper is a surface blobMesh generator for any kind of particle system in 3dsMax, Maya and XSI(not only glu3D particles). Create a new instance of Pwrapper. Then select any particle system through pwrapper command panel and its particles will be wrapped with a poly surface mesh. Modify Pwrapper parameters to change surface look.
