“…To progressively render virtual scenes from a blurred state to a clear state, sequences of LOD models are transferred from coarse to fine. Reference [ 10 ] proposed a novel kd-tree based on a parallel adaptive rendering approach. A two-level framework for adaptive sampling in parallel is introduced to reduce the computation time and to lower the memory usage.…”

To automatically adapt to various hardware and software environments on different devices, this paper presents a time-critical adaptive approach for visualizing natural scenes. In this method, a simplified expression of a tree model is used for different devices. The best rendering scheme is intelligently selected to generate a particular scene by estimating the rendering time of trees based on their visual importance. Therefore, this approach can ensure the reality of natural scenes while maintaining a constant frame rate for their interactive display. To verify its effectiveness and flexibility, this method is applied in different devices, such as a desktop computer, laptop, iPad and smart phone. Applications show that the method proposed in this paper can not only adapt to devices with different computing abilities and system resources very well but can also achieve rather good visual realism and a constant frame rate for natural scenes.

“…Clargerg et al analyze the environment light by wavelet and focus on the high weight area of the scene [8]. To render more effects, adaptive sampling is used in multidimensional sampling [1,9]. To avoid dimensionality curse, some method can get non-image variance based on image analysis [10,11].…”

Global illumination is important and hard to render in computer graphics. We propose a novel technique to generate high quality global illumination images using regression analysis. Our algorithm has two stages. During sampling stage, we get the indirect light field and use it to train an artificial neural network model. In reconstruction stage, the neural network model is used to synthesize the final image. The experiments show our algorithm generates higher quality images than the previous methods.

Models recommendation is always a key part in part-composition system based on sketch. In this paper, proper models are suggested via three steps. Firstly, the possible type of model parts is suggested according to the topological features. Then toy parts that have similar profile types with the inputted sketches are clustered and recommended by lineage clustering method. Finally, based on the promoted $1 recognizer, the suggested parts are sorted according to the shape similarity with the inputted sketch. Experimental results show that the models can be recommended quickly and properly via our method.
