Abstract. Real-Time rendering of reliable clouds has become indispensable for state-of-the art multimedia applications. However, the cost of real-time for this natural phenomena has been a challenge in the last decades. This paper presents a new approach for cloud dynamics and rendering based on General-Purpose Computing on Graphics Processing Units (GPGPU) that achieves realistic cloud movement and morphing of 3D meshes with parallel paradigms. As a result we demonstrate a significant increment of performance by using Compute Unified Device Architecture (CUDA) technology in comparison with old-fashioned serial algorithms.
