A Web3D modeling optimization algorithm based on cylindrical projection

To a Web3D virtual reality scene, the clarity of objects and the fluency of interaction are the two most important factors on affecting users´ experience. They are both constrained by the performance of the modeling algorithm. In order to overcome the bottlenecks of existing modeling algorithms, a Web3D modeling optimization algorithm based on cylindrical projection is proposed in this paper. Algorithm exchange 3D object model into cylindrical images and introduce a type of optimized strategy to reduce the number of models needed to be projected and blanked with the help of intermediate results during the period of interactive calculation. Finally, we design some tests which show that the algorithm performs better than other algorithms on the construction of complex scenes.
