3D Mesh & Texture Processing 3D Models

Mesh & Texture

Processing

• Adaptative LOD generator for solid and smooth models • Embedded Multi LOD preserving whole shape • Multi Resolution Texture • Process time is depending of

• Models Topology • Texture Organization

• Easy integration in an process workflow using batch method.

Compression and Storage

• Compress Mesh and Texture LOD • High Compression Ratio

• Very High Quality from 1:20 to 1:50 • Good Quality up to 1:100

• Scalable Performance based on GPGPU • Compressed file format generation

USE CASES

Storage Reduction

• CAD/CAM – Visualize 100 Millions polygon assemblies

on any type of devices – Batch process of 120 minutes to generate 7 LOD – Compress data in 2 minutes. – Reduce the file size by 40.

Reverse Engineering

• Make Scan to generate CAD/CAM model to integrate in PLM process for maintenance – LOD Generator can process 1M Triangle / minutes – Visualize up to 60 M using 7 LOD – Reduce the files size by 30 – Reduce the loading time

Collaborative Engineering

• Manufacturing Process Review – Visualize and interact on the same model using local and remote device – Use Compressed Format to stream the model over the network. – Decompress on remote device using OpenCL – User set the appropriate Level Of Detail on remote device manually or

automatically – Reduce the Bandwidth – All remote user to show the model – Possible integration on existing Framework
