Procedural weathering
Abstract
Pintojen ikääntymisen kuvaaminen on tärkeä osa virtuaalisten
maailmojen uskottavuutta. Olemassa olevat ikääntymistekniikat ovat usein joko yksittäiseen
ikääntymisilmiöön keskittyviä simulaatioita tai puhtaasti visuaalisia malleja, jotka
eivät pysty mallintamaan ilmiöiden syntymekanismeja. Meidän mallimme asettuu näiden
tekniikoiden väliin. Se on visuaalinen malli, jolla voidaan approksimoida useiden ikääntymisilmiöiden
syntymekanismeja muutamilla parametreilla. Mallimme on riittävän nopea
käytettäväksi interaktiivisena työkaluna. Malli voidaan toteuttaa yleisesti saatavilla olevilla 3D-mallinnusohjelmilla ilman ohjelmointitaitoja, joten se soveltuu tiedeyhteisöä laajemman
yleisön käytettäväksi.
Representing weathering of surfaces is an important aspect when creating believable virtual worlds. Existing weathering techniques are often either simulations concentrating to a single weathering phenomenon at a time, or pure visual models that do not have a connection to the birth mechanisms of the phenomenon. Our model fits in between these two techniques providing a visual weathering model that approximates real world birth mechanisms with a small set of parameters, which can be used for several weathering phenomena. Evaluation of our model is fast enough to be used as an interactive tool. Our model can be implemented on commonly available 3D-modeling software without programming skills required, which makes it suitable for audiences larger than the science community.
