In subject area: Computer Science A 'Projection Operation' refers to the process of finding the point in a closed convex set that is closest to a given point. It is a fundamental mathematical concept used in optimization tasks and generalizes to various spaces including Hilbert spaces. ...
Hybrid X-ray and magnetic resonance (MR) imaging promises large potential in interventional medical imaging applications due to the broad variety of contrast of MRI combined with fast imaging of X-ray-based modalities. To fully utilize the potential of the vast amount of existing image enhancement...
This simplification was super important in a time where most machines did not have the horsepower to process real-time 3D polygons and perform fast 3D math. And this was also true for non-isometric games as well. For example, the gameDonkey Kong Countrymight have a 3D "feel" to it, but...
Computer graphics systems provide sophisticated means to render virtual 3D space to 2D display surfaces by applying planar geometric projections. In a real... FRANK STEINICKE,GERD BRUDER,SCOTT KUHL - 《Acm Transactions on Graphics》 被引量: 41发表: 2011年 An Efficient Mesh Simplification Method wit...
Static hologram print services have already been commercialized1,2, and 3D models designed in computer graphics can be printed out as full-colour holograms based on the well-known holographic stereogram (HS) technique. In contrast, dynamic holographic displays are still at the research stage, and ...
In computer graphics a projection describes the mapping of scene geometry to the screen. While linear projections such as perspective and orthographic projection are common, increasing applications are being found for nonlinear projections, which do not necessarily map straight lines in the scene to str...
computer graphicsorthographic projection Orthographic projection is a fundamental projection technique that transforms objects in a higher dimension to a lower dimension. This transformation is usually used for objects in a 3d world to be rendered into a screen (a 2d surface) and in the process keeps...
The objective of this research is to develop a generic 4D graphics library, 4DGL, and spread the use of 4D graphics in the design field. This library is implemented on POV-Ray, a free 3D computer graphics tool, and can describe 4D shapes themselves and manipulation of the 4D shapes using...
