TunVis: Visualizing specific geologic features for tunnel planning and construction
نویسندگان
چکیده
This paper describes a method and a system for visualizing a virtual tunnel through an existing geologic formation and a method for the generation of a camera animation along the tunnel axis. The tunnel is built from geologic data coming from vertical sample drills from the mountain top along the selected tunnel axis. Its wire frame model is then edited by a geologist and image information of the rock appearance is textured onto the tunnel wall, resulting in a photorealistic representation of the expected geologic rock formations. Finally a camera animation and video options are defined to render a video sequence of the camera movement.

A Geologic Prediction Model For Tunneling
Geologic uncertainty in underground construction often leads to design and construction conservatism and hence to inflated costs. This paper presents a general model for the probabilistic prediction of tunnel geology, as a basis for developing more effective tunnel design and construction decision support systems. The geologic conditions along the tunnel alignment are modeled by a set of geolog...
متن کاملDevelopment of SISGeM - An Online System for 3D Geologic Modeling -
GIS can be readily used to manage and analyze 2D information and also afford 3D visualization of surface features. However, general-purpose GIS packages do not offer capabilities for constructing or visualizing 3D geologic models. GIS tools must, therefore, be appropriately tailored to handle geologic data and accommodate the special spatial analysis needs of geologic information. Since 3D geol...

Among different staining methods used to demonstrate the nuclear abnormalities, Feulgen is one of the most reliable method. Feulgen staining is specific, sensitive method for evaluating the DNA damages.It has been shown that using non-DNA specific stains for monitoring the nuclear anomalies lead to false-positive or false-negative results. From self-experience, immersing the stained slides in h...
متن کاملDesign Algorithm of a Free Surface Water Tunnel to Test the Surface-Piercing Propellers (SPP); Case Study Water Tunnel of Babol Noshirvani University of Technology
Surface-Piercing Propellers (SPPs) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. Unlike the submerged propellers, theoretical methods have no significant application on simulation of SPPsbecause of problems related to modeling of these propeller...
