A Survey of Haptic Rendering Techniques

Computer Graphics Forum, 2007
AbstractComputer Graphics technologies have developed considerably over the past decades. Realistic virtual environments can be produced incorporating complex geometry for graphical objects and utilising hardware acceleration for per pixel effects. To enhance these environments, in terms of the immersive experience perceived by users, the human's sense

Sensation-preserving haptic rendering

IEEE Computer Graphics and Applications, 2005
Most human-computer interactive systems focus primarily on the graphical rendering of visual information and, to a lesser extent, on the display of auditory information. Haptic interfaces have the potential to increase the quality of human-computer interaction by accommodating the sense of touch.

Haptic rendering and control

, 2008
In haptic simulations a human operator is coupled to a virtual environment, in such a way that the user is able to perceive the scene with his/her sense of touch. In Figure 1 the interaction paths between user and virtual world are shown. To obtain a good level of immersion, at least two interaction paths must be provided for haptic simulations, namely

Haptic Rendering of Point Set Surfaces

Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (WHC'07), 2007
We present a haptic rendering algorithm for a point set surface. Given a point set, its point set surface is an implicit surface defined by local projection of point sets using the moving least square (MLS) method. Our haptic algorithm is a penalty-based method which requires a calculation of the minimum distance between the haptic interaction point ...

Introduction to haptic rendering

ACM SIGGRAPH 2005 Courses on - SIGGRAPH '05, 2005
For a long time, human beings have dreamed of a virtual world where it is possible to interact with synthetic entities as if they were real. To date, the advances in computer graphics allow us to see virtual objects and avatars, to hear them, to move them, and to touch them.

Haptic rendering of photographs

2012 IEEE International Workshop on Haptic Audio Visual Environments and Games (HAVE 2012) Proceedings, 2012
Exploration of 2-D images is a challenging problem in computer haptics and research has primarily been focused on the exploration of restricted types of images, e.g., maps or mathematical curves. In contrast, this paper describes the design and implementation of a system for the haptic exploration of general photographs.

Haptic Rendering of Mixed Haptic Effects

2010 International Conference on Cyberworlds, 2010
Commonly, surface and solid haptic effects are separated for haptic rendering. We propose a method for defining surface and solid haptic effects as well as various force fields in 3D cyber worlds containing mixed geometric models, including polygon meshes, point clouds, image-based billboards and layered textures, voxel models and functions-based ...

Haptic Rendering of Compliant Shapes

IEEE Transactions on Robotics, 2015
Dynamically controlling the shape of an object by means of a 3-D shape interface offers many new opportunities in the fields of virtual reality and design as direct exploration of objects becomes feasible. Using a parallel kinematics as 3-D shape interface comes with features such as high stiffness and speed, but requires a series of points to be ...

Rendering of Constraints With Underactuated Haptic Devices

IEEE Transactions on Haptics, 2020
Several previous works have studied the application of proxy-based rendering algorithms to underactuated haptic devices. However, all these works make oversimplifying assumptions about the configuration of the haptic device, and they ignore the user's intent.
