General Overview of NLPACS

Introduction

The NeL PACS library comprises world surface representations for content movement and collision management for both server and client applications.

Both landscape and enclosed spaces are supported.
PACS can either be linked to application as a library or run as a pair of stand-alone service.

There is support for both object-object collisions and object-scenery collisions.
Objects are divided into static solid objects, dynamic solid objects and dynamic 'ghost' objects that have no impact on the scenery
Both Logical collisions and Blocking collisions are supported
Blocking collisions may be treated as 'sticky', 'sliding' or 'bounce'
Object collision primitives include cylinders and cuboids.
PACS may maintain a collision space history which allows re-tracing of movement information received late, by the server, through the world as it was for lag management purposes.

Landscape scenery is converted directly to a surface representation by exported data re-processing utilities.
Streets and interiors must have explicit collision models (surface models) which are exported from 3DStudio Max and processed to generate the same surface representation.
