3Space Assistant from TGS
3Space Assistant lets you visualize, communicate and exchange 3D
design information. It includes a feature to decimate large
objects. This feature was originally released as a separate
product called 3D decimator.
Action3D from Action3D Inc.
Lets you import .3ds and .x files and vary the model's
LOD using a slider control (based upon progressive mesh
technology). Uses DirectX and runs on Windows 98, Me,
2000, and XP. There is a free demo version and a full
license sells for a low $50.00.
Balancer from Atangeo
Atangeo Balancer is a tool that allows you to find perfect balance between
visual appearance and the number of polygons, quickly and easily.
Balancer utilizes a high quality polygon reduction to preserve the
visual appearance of your model.
The model features, normals, texture coordinates, layer boundaries are
Chisel from Trapezium
Chisel optimizes and validates VRML .wrl files. It includes
a number of polygon reducing techniques including merging
coplanar triangles, edge collapse, and triangle collapse.
Chisel can also adjust numeric resolution of coordinates
and remove unused coordinates.
Geomagic Decimate from Raindrop Geomagic
Geomagic Studio is a CAD/CAE/CAM application that supports
the Windows and Solaris platforms. It contains the Geomagic
Decimate component that performs polygon reduction, preserving
surface curvature and minimizes surface errors. Supported file
formats include .obj, .3ds, .dxf, and .wrl. Geomagic Decimate sells
for $295 (as of 8 Sept 2001).
Polygon Cruncher from Mootools Software
A plugin for Lightwave, 3DS Max, and 3D Photo Browser that
lets you reduce the number of polygons in your objects without
affecting their appearance. Supports models with textures and
vertex coloring. Also includes an OpenGL view and a batch
Progressive Fans by Antonio Cortés Carrillo
Progressive Fans are a technology for progressive transmission
and view-dependent simplification of manifold and non-manifold
meshes. The application that builds the LODs uses Garland's
quadric error metric and a volume heuristic.
Progressive Meshes Maya Plugin by Erik Pojar
Erik has written a Maya Plugin that implements a progressive
mesh scheme using quadric error metrics. Additionaly, the user
can supply custom weights (using Maya's Artisan interface) to
control the aggressiveness of the simplification in different
parts of the model. Full source code is provided.
ProgMesh from Paralelo Computação
ProgMesh is a Windows 9x/NT application for 3D polygon mesh
simplification which supports the 3DStudio file format. A
progressive file format is used allowing progressive downloads on
the Internet to any level of detail. Texture maps are also
downloaded progressively if in WLM format. The unregistered version
only imports objects with less than 6000 polygons.
Rational Reducer from Systems In Motion
Rational Reduced is a high-end polygon reduction tool with support
for the follow file formats: .3ds, .dxf, .flt, .wrl. The product
runs on Windows, IRIX, HP-UX, and Linux operating systems. Cost
begins at $4,950 for 1 user and goes down to $3,710 for 7-10 users
(as of 8 Sept 2001). A Software Development Kit is available to
integrate this functionality in your own programs.
RXpolyred from Realax
RXpolyred is a graphical polygon reduction tool available for SGI and
Windows NT platforms. Materials, textures, surface-curvature and
object hierarchy are all preserved, and RXpolyred can also
calculate the switch-out-distance for each level of detail.
RXpolyred is integrated in RXscene which supports .dxf, .iv, .flt,
.wrl, .3ds, .obj, among others.
Simplygon is a versatile and powerful tool for
optimizing 3d polygon mesh models, including high-quality
polygon reduction and polygon repair-features. You can use
Simplygon to automatically repair and reduce the size and
complexity of your 3d polygon mesh models. Simplygon can be
used for creating highly optimized level-of-detail (LOD)
objects, and optimizing 3D models for simulations and
TerraVision is 3D terrain visualization system that lets you browse
massive terrain datasets over the Web. Multiple datasets from
different servers around the Web can be streamed and fused into a
single coherent representation of the planet. The software is
freely available for noncommercial purposes on Windows, Linux, and
Silicon Graphics platforms.
Virtual Terrain Project (VTP)
The VTP site is maintained by Ben Discoe with the goal to foster
the creation of tools for easily constructing any part of the real
world in interactive, 3D digital form. This includes Open Source
software for all stages of the terrain production process. To
receive the source code, you must register (it's free) with Ben.
VIZup Optimizer from Sergei Zawelsky.
VIZup is a product for reducing the complexity of your
VRML 3D models. VIZup attempts to automatically
preserve the visual quality as much as possible while
users tune the polygon count to suit their needs. The
author reports that this software uses
custom genetic algorithms to achieve this goal.
