A multilevel detail algorithm based on a quadtree is a method for effectively rendering a VR scene, and as shown in fig. 3, a specified three-dimensional space region is divided into four spaces by the structure of the quadtree according to four quadrants of a horizontal plane. Each node of each quadrant, except for the leaf nodes, has 4 children nodes that equally divide the area occupied by their parent nodes until a leaf node occurs. A leaf node is a very special node, which has no children, and is the smallest unit in which rendering and mapping are performed. The multilevel detail algorithm based on the quadtree flows as follows:
after receiving the scene data, the rendering processing unit divides the vertex coordinates (x, y, z) of each three-dimensional element into two parts, namely, the (x, z) part and the (y) part. Where y is the height of the vertex. In the three-dimensional rendering process, the whole environment to be rendered is regarded as a rectangular grid, the requirement of the rendering precision value of the three-dimensional element of the node is determined according to the distance between the node and the position of an observer and the flatness, and the rendering progress requirement corresponding to the position of the node with lower flatness is higher as the distance is closer, the corresponding quadtree node needs to be further subdivided.
As shown in FIG. 4, the distance from the center of the node to the observer is d, d can be obtained according to (x, z), the side length of the node is l, and a grid division factor C is set1When is coming into contact with
If the ratio is larger than the grid division factor, then no further division is needed,mesh partitioning factor C1The larger the value of (a), the higher the rendering accuracy of the scene.
As shown in FIG. 5, the central point of a quadtree node and the middle point of its boundary are o and p, respectively1、p2、p3、p4Definition of dp1Is p1Dividing the sum of the heights of two vertexes of the boundary where the point is located by 2 and then summing p1Is the result of the subtraction of y, dp1Can represent p1The flatness dp of the other three edges can be calculated by the same method2、dp3、dp4. The flatness between the vertex of the quadtree node and the central point o is calculated in the following manner: the sum of the height values of the four vertices of the node is divided by 4 and then the difference is made with the height value of o. And is counted as do. Max (dp)1、dp2、dp3、dp4Do) represents the maximum value between the five flatness levels, if any. Max (dp)1、dp2、dp3、dp4、do)＞C2And if so, judging that the flatness of the node of the quadtree is low and further division is needed. C2The smaller the set value is, the higher the rendering accuracy of the scene is.
Through the judgment process, the rendering flag bit is set to be true for the situation that the rendering is needed to be subdivided according to the quadtree thought, and the rendering mapping is carried out without further subdivision. The structure of the QuadTree data is as follows:
Class QuadTree
{
int index；
int depth；
int width；
position3D position；
QuadTree*father；
QuadTree*children[4]；
Mesh mesh[n]；
}
wherein index is the sequence number of the tree node; depth describes depth information of the quad tree nodes. The depth information of the root node is 0, and the depth information of its four child nodes, i.e., the four nodes of the first layer, is 1, and so on. The depth information is mainly used for detecting the depth of the tree structure in real time by a program; the position mainly records the central point of the spatial position of the quad-tree node, and the width records the position from the central point to the spatial boundary. Because the space is a three-dimensional space from bottom to top by taking the horizontal plane as a reference plane, the three-dimensional space can be completely restored by utilizing a central point coordinate and a distance value; the history records all model nodes in the three-dimensional space surrounded by the leaf node through the parent node mesh of the node.
The invention adopts an iteration method to complete the generation of the whole tree structure, and completes the generation of all the quad-tree nodes from top to bottom through circular calling.
As shown in fig. 2, the process of the rendering processing unit includes:
receiving three-dimensional scene data sent by a server;
acquiring three-dimensional coordinates of each three-dimensional element vertex in three-dimensional scene data;
determining the range of the root node according to all three-dimensional model elements in the three-dimensional scene data, namely initializing the root node;
