Research on Scene Organize Algorithm Based on BVH with Dynamic Rendering Tree Li XU1,a, Maozhen LIU2,b 1 Computer College, Beijing Information Science and Technology University, Beijing 100101, China 2 Virtual Reality and Simulation Laboratory, Beijing Information Science & Technology University, Beijing 100192, China aemail:xuli_lh@139.com, bemail:liumaozhen123@126.com KEYWORDS：Scene Organize; Multimedia Technology; Rendering Tree; Scene Management ABSTRACT: The real-time rendering of 3D scene need excellent algorithm to support scene management.
For example, suppose there is such a scene, in a room with three computers on three desks respectively, two material cabinets, three chairs, for such scenes, we can organize the structure of the scene through the following steps: first, to determine the object in the scene, computer, desk, chair, material cabinet; then determine their relationships, material cabinet and chairs can be regarded as independent that can be drawn, with independent bounding box to represent the object's bounding volume, the computer on the desk, we can put a desk and the corresponding computer to be surrounded in the body, desk and computer in separate surrounded in the body, similar to the other two desks and computers; finally, determine the hierarchy, according to the three branches under the root node, respectively organize material cabinets, chairs, desk, computer, but computer and desk is divided into two branches, respectively is a desk and a computer.

Experimental blanking die Table 1 shows mechanical properties of the work materials to be blanked in the experiment, from Table 1, we can see the work materials include 3 types SPCC sheet steel, 2 types sheet aluminum and 2 types sheet copper, and their thickness, hardness and tensile strength have been measured in the experiment.
Table 1 Mechanical properties of the work materials Work Materials Thickness (mm) HV Hardness （MPa） SPCC 1.5 116 300 SPCC 1.0 124 320 SPCC 0.5 148 380 AL 2.0 37 90 AL 1.0 40 100 H62 1.5 81 300 H62 1.0 85 310 Experimental Results and Analysis.
In addition, read by noise meter is uncertain for some materials with lower HV hardness and lower tensile strength, even lower than press machine’s no-load noise value.
It is clearly defined that Eq. 2 only applies to those materials whose HV hardness is from 10 to 600[5].

Experiment 1.1 Experimental materials and pretreatment Thlaspi caerulescens L. rich in selenium is collected from Yu Tangba of Enshi, Hubei Province, while the normal thlaspi caerulescens L. is collected from the mountain behind Hubei Institute for Nationalities.
Seen from Figure 2, both thlaspi caerulescens L. and selenium thlaspi caerulescens L.in thlaspi caerulescens L. have clear role of scavenging O2-•, and from 60s-180s, the scavenging capacity and the amount the samples form a certain linear relationship, with the capacity enhancing with the increasing of the amount of materials.

The application of composite materials in the framework of aerospace structures has been growing up due to high stiffness and strength-to-weight ratios but also to the path-loads management capability [1].
The analyzed configuration consists of cross-ply graphite-epoxy stack while PZT-5A material is used to arrange the sensing device.
