Global Selection of Stream Surfaces
Stream surfaces are well-known and widely-used structures for 3D flow visualization. A single surface can be sufficient to represent important global flow characteristics. Unfortunately, due to the huge space of possible stream surfaces, finding the globally most representative stream surface turns out to be a hard task that is usually performed by time-consuming manual trial and error explorat...
متن کاملTopology Aware Stream Surfaces
We present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the computation considerably and may lead to a poor surface approximation. Alternatively, the concerned region is omitted from the stream surface by severing it into two parts thus gen...
متن کاملStreamarrows: Visualizing Multiple Layers of Stream- Surfaces
Occlusion is a crucial spatial cue for the human visual system. Painters as well as researchers in the eld of computer graphics have been dealing with this aspect for a long time. In the eld of visualization occlusion can be especially problematic. We present a new approach to dealing with streamsurfaces that occlude major parts of the system representation. Analyzing mixed-mode oscillations, w...
متن کاملEffect of black surfaces to increase the average surface temperature of the earth: A global warning!
Gradual increase of the Earth's surface temperature can cause many significant changes on the climate of our planet. This problem is progressively increasing. One of the main reasons for this phenomenon is the absorption of the Sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. In this descriptive and cross-sectio...
متن کاملStream Processing in Global Illumination
This paper presents the implementation of the stochastic radiosity algorithm on the graphics hardware. We store the radiosity function in texels of the floating point pbuffer. The radiosity function is updated in each iteration. When converged, the radiosity function is mapped onto surfaces by traditional texture mapping. Our goal is to enable interactive radiosity style rendering of scenes wit...
