Diversi tra questi fenomeni sono visualizzati nel <strong>di</strong>mostratore<br />
VCL.<br />
Il VCL inoltre mostra i fenomeni <strong>del</strong> colore non connessi<br />
ad una specifica situazione spaziale (ve<strong>di</strong><br />
Figura 3). Quando deve confrontarsi con combinazioni<br />
<strong>di</strong> colori e schemi a due <strong>di</strong>mensioni, il nostro<br />
senso <strong>del</strong>la vista spesso crea ciò che comunemente<br />
vengono chiamate “illusioni ottiche”. Possiamo<br />
percepire relazioni <strong>di</strong> luminosità o <strong>di</strong>fferenze <strong>di</strong><br />
tinta che non si conformano con i colori naturali<br />
esistenti (ad es. illusione <strong>del</strong> Bianco ed illusione <strong>del</strong><br />
Diamante), o contesti spaziali che non esistono fisicamente<br />
(ad es. l’illusione <strong>di</strong> Chevreul). Possiamo<br />
anche combinare le esperienze <strong>del</strong> colore <strong>di</strong> superficie<br />
e luce. Molte <strong>di</strong> queste illusioni sono state presentate<br />
con successo in forma bi-<strong>di</strong>mensionale, e<br />
la sfida specifica all’interno <strong>del</strong> progetto VCL è stata<br />
<strong>di</strong> mostrarle in un ambiente spaziale tri-<strong>di</strong>mensionale<br />
<strong>di</strong>gitale .<br />
Problemi legati alla progettazione<br />
<strong>di</strong> <strong>di</strong>mostratore <strong>del</strong> colore interattivo<br />
Il lavoro con il progetto VCL ha rilevato numerosi<br />
problemi connessi alla riproduzione <strong>del</strong> colore in<br />
ambienti virtuali (AV) così come problemi generali<br />
concernenti il progetto <strong>di</strong> un AV. Il realismo, l’interattività<br />
e le possibilità per l’orientamento spaziale<br />
all’interno <strong>del</strong> mo<strong>del</strong>lo sono temi frequentemente<br />
<strong>di</strong>scussi nella ricerca riguardante gli AV, mentre le<br />
<strong>di</strong>fficoltà riguardanti la riproduzione <strong>del</strong> colore sottolineano<br />
il bisogno <strong>di</strong> ulteriore ricerca in questo<br />
campo. Questi temi sono oggetto <strong>di</strong> una recente<br />
<strong>di</strong>scussione <strong>di</strong> dottorato da parte <strong>del</strong>la Stahre 6 .<br />
INVITO ALLA COOPERAZIONE<br />
La versione esistente <strong>del</strong> VCL è un prototipo che al<br />
momento è in corso <strong>di</strong> valutazione da un numero<br />
<strong>di</strong> potenziali utenti provenienti da vari ambiti professionali.<br />
Speriamo <strong>di</strong> avere in futuro la possibilità<br />
that do not physically exist (e.g. Chevreul illusion).<br />
We can also mix the experiences of surface colour<br />
and light. Many of these illusions have been successfully<br />
presented in two-<strong>di</strong>mensional form, and<br />
the specific challenge within the VCL project has<br />
been to demonstrate them in a spatial <strong>di</strong>gital three<strong>di</strong>mensional<br />
environment.<br />
Problems of designing an interactive<br />
colour demonstrator<br />
The work with the VCL-project has revealed several<br />
problems connected to colour reproduction in virtual<br />
environments (VEs) as well as general problems<br />
regar<strong>di</strong>ng the design of a VE. Realism; interactivity<br />
and possibilities for spatial orientation within the<br />
mo<strong>del</strong> are issues frequently <strong>di</strong>scussed in research<br />
concerning VEs, whereas the <strong>di</strong>fficulties regar<strong>di</strong>ng<br />
colour reproduction highlight the need for further<br />
research in this field. These issues are the subject<br />
of a recent doctorate <strong>di</strong>ssertation by Stahre 6 .<br />
INVITATION TO CO-OPERATE<br />
The existing version of the VCL is a prototype which<br />
at present is being evaluated by a number of potential<br />
users from <strong>di</strong>fferent professions. We hope that<br />
we will get the possibility to continue the project<br />
and develop the VCL into a platform for showing colour<br />
research results from all over the world. Therefore<br />
we invite you all to <strong>di</strong>scussions about possible<br />
future co-operation around this project.<br />
<strong>di</strong> proseguire il progetto e sviluppare il VCL in una<br />
piattaforma per mostrare i risultati <strong>del</strong>la ricerca sul<br />
colore da ogni parte <strong>del</strong> mondo. Perciò vi invitiamo<br />
tutti alla <strong>di</strong>scussione circa una possibile collaborazione<br />
futura intorno a questo progetto.<br />
