Normalpaint: uma ferramenta interativa de pintura de normal maps em modelos 3D

Abstract

This work presents a novel model of creation and modification of normal maps, using a intuitive interface similar of a paint system. These maps are crucial to graphical applications, processed in real time, that claims better visual realism. Most digital games use this technology, allowing the recreation of the visual complexity of a dense geometric 3D model, in a simplified model. That way game utilize only the lighter model to process, but can render the details on the object that create the illusion of geometric complexity. The creation process of this normal map is very labor intensive. An artist must create the simplified model that will be used in game, besides another model that is as complex as desired. This last model will be used only as a reference to extract the normal

map in a 3D software. Then the normal map is applied in the simpler model, that is rendered with the visual detail the normal map represent. This work presents a computacional model that propose the concept of eliminate the creati
