The Basic River Rapids Library contains 13 high-resolution, physically accurate mesh models of river rapids. It includes 5 optional river elevation planes for the rapids. The rapids in this Library are of the kind formed by moderate changes in elevation of the river or stream bed, and/or by the flow of water rushing by one boulder, or between two boulders. Each model of a rapid is formed in two pieces - one for the air entrained within the water ('foam') and the other for the plain water. You can delete either of these sub-components to reduce the overall polygon count of your scene. Please download and read the five-page User Guide for a better description of the models in this package. ------->
