The present invention provides a method for approximately rendering soft shadows in a three-dimensional scene. This method estimates the visibility of the planar light source in the visible scene area by random sampling of the planar light source, and uses spatial convolution smoothing and denoising filtering to reduce the visibility noise of the planar light source introduced by random sampling; technology, according to the obtained visibility data of the plane light source of the visible scene point, calculate the illumination contribution of the plane light source to the visible scene point, and finally calculate the color value of the visible scene point based on this, and draw a soft Shaded 3D scene footage. The method can improve the drawing speed while ensuring the drawing quality of the three-dimensional scene picture.

The invention provides a three-dimensional dynamic data compression and a smoothing method based on image space. The three-dimensional dynamic data compression and the smoothing method based on image space include compressing a sampling point which is projected on a server-side based on the image space, firstly calculating space position of the sampling point at a certain internal, then conducting cluster compression on a motion track to greatly improve data compression rate, conducting smoothing process on a transition area between a client-side and an adjacent rigid body, eliminating gaps between the adjacent rigid body when compression rate is overlarge, and enabling the server-side to transmit dynamic data when the compression rate is overlarge. In a traditional method of interactive three-dimensional figure visualization, when a client-side viewpoint parameter changes, the server-side needs to redraw and transmit a figure with novel viewpoint, and frequent changes of the client-side viewpoint lead to overlarge data transmission amount. The compression of the sampling point motion track can be finished in the image space, GPU parallel calculation characters can be well utilized, rapid and compact compression of the three-dimensional dynamic scene data can be achieved, and limit on a network broadband can be reduced.
