Between sphere performance and building mode just become our inevitable choices.
With the development of numerous 3D open source technologies and universal, but also we carry out ourselves according to the display form wanted
Three-dimensional sphere is fabricated to for a kind of possibility.But it allows and faces more problem and challenge.
Firstly, since needing to find out the basic component units for constituting three-dimensional sphere, as grid type sphere is made using triangle
For the base unit etc. of three-dimensional sphere configuration.And the production of this three-dimensional sphere will be using hexagon as configurational base unit.
Secondly, the aesthetics and intuitive of three-dimensional space sphere.Due to being hexagon to be passed through using the purpose of this method
As the basic unit of building sphere, to show user to carry out visual experience.Therefore how it is clear directly, beautiful table
Up to be need we try to solve the problems, such as.
Furthermore on three-dimensional space sphere the position on each vertex how to determine be also the present invention in primary study place.
Because any three-dimensional bodies and construct the position control for all be unableing to do without vertex, the positional relationship of mistake and put in order will
Keep entire space sphere mixed and disorderly, it is unordered.
Finally, being the line to vertex on space sphere.Since line segment is determined by its endpoint location, Spatial Sphere
Vertex position in body, and endpoint corresponding to every line segment is accurately found, it is that can correctly construct the three-dimensional space ball
The key points and difficulties of body

5. system as claimed in claim 4, which is characterized in that further include computing module one, for according to three institutes found out
The three-dimensional coordinate of the first nodes needed calculates the three-dimensional coordinate of two-level node, calculation formula are as follows:
Two-level node X axis coordinate: B.x=(A (p, q) .x+A (p, q+1) .x+A (p+1, q+1) .x)/3；
Two-level node Y axis coordinate: B.y=(A (p, q) .y+A (p, q+1) .y+A (p+1, q+1) .y)/3；
Two-level node Z axis coordinate: B.z=(A (p, q) .z+A (p, q+1) .z+A (p+1, q+1) .z)/3；
The two-dimensional coordinate A (p, q) that wherein A (p, q) .x, A (p, q) .y, A (p, q) .z respectively indicates first nodes is converted into three-dimensional
The value of corresponding x-axis, y-axis, z-axis after coordinate.
6. system as claimed in claim 5, which is characterized in that further include computing module two, for by being had determined that all
The three-dimensional coordinate of first nodes and the calculation formula that is calculated of the three-dimensional coordinate of two-level node are as follows:
Three-level nodes X coordinate: C.x=A.x+ (B.x-A.x) * 0.25；
Three-level node Y-coordinate: C.y=A.y+ (B.y-A.y) * 0.25；
Three-level node Z coordinate: C.z=A.z+ (B.z-A.z) * 0.25.
