Painting Textures with a Haptic Interface

Simulated 3D Painting

This paper looks at the motivation for simulating painting directly on 3D objects, and investigates the main issues faced by such systems. These issues include the provision of natural user interfaces, the reproduction of realistic brush effects and the surface parameterization for texture mapping so that the results of the painting can be stored on texture maps. The paper further investigates ...

inTouch: Interactive Multiresolution Modeling and 3D Painting with a Haptic Interface

We present an intuitive 3D interface for interactively editing and painting a polygonal mesh using a force feedback device. An artist or a designer can use the system to create and refine a three-dimensional multiresolution polygonal mesh. Its appearance can be further enhanced by directly painting onto its surface. The system allows users to naturally create complex forms and patterns not only...

Simulation of the Admittance Control Based Haptic Interface Device

Stochastic models for haptic texture

Recent research in haptic systems has begun to focus on the generation of textures to enhance haptic simulations. Synthetic texture generation can be achieved through the use of stochastic modeling techniques to produce random and pseudo-random texture patterns. These models are based on techniques used in computer graphics texture generation and textured image analysis and modeling. The goal f...

Judging 2D versus 3D Square-Wave Virtual Gratings

Haptic virtual texture can enhance people's experience in interacting with virtual objects by providing surface information. We present a study to analyze how people distinguish between 2D and 3D square-wave gratings using a point-source haptic interface. Our analyses were based on objective vibration and force measurements and psychophysical experiments with human subjects. The results indicat...
