Real-time Rendering of 3D Clouds
Pantelis Elinas, Wolfgang Stuerzlinger · Journal of Graphics Tools · 2000
The visual realism of a computer graphics simulation of outdoor scenery is greatly enhanced by a realistic display of clouds. In this paper, we present an algorithm based on Gardner's work that can render perspectively-correct 3D clouds in real time on current graphics hardware. The use of 3D ellipsoids as primitives permits even close-ups without the viewer noticing the approximation. We describe an implementation using OpenGL.
