In this work an interactive teaching tool related to the operable virtual 3-D laboratory has being presented. Though defining the lighting and material, and rendering the scene environment, a remarkable virtual laboratory appears as 3-D figures. As well as combining the ramble, animation and interactivity with the 3-D model, a realistic feel of the experiment presents to us. Data information combine with 3-D model achieve a realistic feel of the experiment and to enhance the students’ understanding of some complex concepts. Based on the virtual laboratory model, a group of experiments are developed, including wind tunnel, a Bernoulli equation rig and a stream line rig, etc.
