Realistic and Fast Cloud Rendering
نویسنده
چکیده
Clouds are an important aspect of rendering outdoor scenes. This paper describes a cloud system that extends texture splatting on particles to model a dozen cloud types (e.g., stratus, cumulus congestus, cumulonimbus), an improvement over earlier systems that modeled only one type of cumulus. We also achieve fast real-time rendering, even for scenes of dense overcast coverage, which was a limitation for previous systems. We present a new shading model that uses artist-driven controls rather than a programmatic approach to approximate lighting. This is suitable when fine-grained control over the look-and-feel is necessary, and artistic resources are available. We also introduce a way to simulate cloud formation and dissipation using texture

Realistic Simulation of 3D Cloud
-The digital creation of cloud is important for many applications in computer graphics, including outdoor simulations and the digital rendering of atmospheric effects. Unfortunately, it is still difficult to simulate realistic cloud with interactive frame rates due to its peculiar microstructures and complex physical process of formation. Realistic simulation of cloud turns to be one of the mos...
متن کاملReal-time Realistic Illumination and Shading of Stratiform Clouds
Realistic rendering of clouds involves solving the complex interaction of light within the cloud and with its environment. Interactive methods achieve efficient cloud rendering by ignoring several lighting effects. However, these effects are visually important, and removing them strongly reduces realism. We present a novel approach for capturing the important effects of multiple anisotropic Mie...
متن کاملSVGPU: real time 3D rendering to vector graphics formats
We focus on the real-time realistic rendering of a 3-D scene to a 2-D vector image. There are several application domains which could benefit substantially from the compact and resolution independent intermediate format that vector graphics provides. In particular, cloud streaming services, which transmit large amounts of video data and notoriously suffer from low resolution and/or high latency...
متن کاملA semi-automatic generation method for visually-plausible virtual clouds
Cloud is one of the most important atmospheric effects in computer graphics applications, and there have been lots of research results on it. Although they have mainly focused on the modeling and rendering of more realistic clouds, nowadays flight simulation games or even full-scale flight simulators often need a quantity of visually plausible clouds rather than realistic ones. Furthermore, we ...
متن کاملReal-Time Cloud Rendering
This paper presents a method for realistic real-time rendering of clouds suitable for flight simulation and games. It provides a cloud shading algorithm that approximates multiple forward scattering in a preprocess, and first order anisotropic scattering at runtime. Impostors are used to accelerate cloud rendering by exploiting frame-to-frame coherence in an interactive flight simulation. Impos...
