BASIC MOUSE CONTROLS:
This viewer is not a complete, standard
compliant,
VRML browser, because VRML objects decoding is not always guaranted.
It's
more a high performance viewer dedicated to high
quality real time visualization, and
associated
to well-defined and carefully prepared data bases:
In general, available VRML objects are not very
complex, levels of details are not computed. Moreover, commercial
viewers
don't implement correctly textures, highlights, etc...Our brother is
dedicated
to high quality rendering for complex, scalabled and detailed data
bases.
particularly for large patrimonial architectures and "Cultural
Heritage"
monuments.
However, Viewer_Texture is VRML1 and 2
compatible,
but don't parse all VRML known nodes. (Even commercially available
browsers
don't !) Geometric nodes are completely decoded. Any VRML1 or 2 objects
are not guaranted. But objects generated by 3DSTUDIO VRML plugin are
fully
decoded, and 100% guaranted.
MAIN FEATURES:
Fast texture and material rendering have been
carefully enhanced compared with other available products.
This viewer is particularly dedicated to very
large 3D data bases real time rendering such as:
- Virtual Museums
- Virtual commercial galleries
- Historic reconstructions
- Prehistoric or historic sites or events
reconstitution.
CHARACTERISTICS:
Several objects have been tested, and other
tools have been designed for automatic 3D objects decimation , in order
to compute levels of details in real scenes. This capability is very
important
for rendering large data bases on small PC's with openGL graphic boards.
REQUIREMENTS:
As any 3D real time viewer, Viewer_Texture need
mandatory a recent, low cost 3D openGl compatible graphics card.
(NVIDIA
or ATI Radeon or ex Guillemot Xentor, Accelgraphics, Diamond or Optia
are
quite suitable).(cost for Xentor: about 1500 €)
Except for the graphic card it is absolutely
not
necessary to use a powerfull PENTIUM V XXX Mhz: A simple 200 or 233 is
quite sufficient, provided that a convenient graphics card is installed.

DETAILED CHARACERISTICS:summary
- VRML1 and VRML 2objects are generally
read
by our browser, but are not guaranted.
- IGN files are decoded (see TROCADERO and
"Quartier de l'etoile" examples)
- Objects generated by VRML1 or 2 3DSTUDIO
Max plugins work fine. (100%
success tested)
- Other exotic file, with # inserted in the
VRML syntax, or having several "indexfaceset" keywords per object,
not separated by "DEF" may be decoded, but without warranty.
- Comportmental nodes are not yet decoded.
- All shape (geometric nodes) are fully
decoded
on VRML1 or VRML2 files.
