The 3D scene test data source of performance bottleneck analysis and resource optimized distribution method. (1) Virtual park scene of the data source. (2) Power plant scene of the data source. (3) Virtual city scene of the data source. This group figure describe the test data source of performance bottleneck analysis and resource optimized distribution method for IoT cloud rendering computing system in cyber-enabled applications. These data source provided by Middlebury, Canada (http://pointclouds.org/ [23]). We select the test models with the largest number of patches, vertexes, and the largest amount of data as experimental test model data. These representative models are selected according to the standard of include most IoT cloud rendering computing system scenarios and most amount of data. Moreover, these models have typical loading times and operational characteristics. If our algorithm works well on these characteristics models, it will work well on other scene models as well. In this group of models and scenes, we selected some 3D model test data set from Middlebury, Canada. The first sub-figure is a virtual park scene and related models, the second sub-figure is a power plant scene and related models, and the third sub-figure is a larger virtual city scene and related models. The following are advantages of scene and models:(1) under different influence of network congestion, these scenes and models show different rendering effects. These models are greatly influenced by different network speed, network congestion, algorithm, and parameters. So this kind of model can distinguish different network congestion situations and different algorithms efficiency. It could truly distinguish the advantages and efficiency of different method. (2) These scenes and models contain more vertexes, edges, and triangular patches, which can distinguish complex method effect easily in graphics. (3) These scene and models include the brightness, hue, and saturation of scene color. These scenes and models will show different rendering effects under different rendering method and procedures. These scenes and models have high discrimination and expressiveness for different algorithms
