Stretch tree
The Splay Tree, also known as the split Tree, is a binary sorting Tree created by Daniel Sleator and Robert Tarjan, which improves it.
Assume that you want to perform a series of search operations on a binary search tree.To make the entire search time shorterHigh query frequencyThose entries should always be near the root of the tree.So I thought of

The 13th chapter introduces some basic kinematics and the difference between forward and reverse kinematics. In the previous chapter we talked about forward kinematics, and this chapter will study the inverse kinematics which is closely related to it. The action involved is dragging and stretching.
As in the case of forward kinematics, the example in this chapter is also to establish a system from an indepe

The splay tree, or the adaptive find tree, inserts, finds, and deletes operations in the time of O (Logn).The aim of the stretching tree is to keep the articles with high frequency of being looked at in close proximity to the roots. It does this by splay the node that is being looked up to the root node after each lookup.Using a stretch tree requires a 90-10 rule: in practice, 90% of access occurs on 10% of the data.Pros: No need to record redundant i

Cliff with texture stretching Problems
Solves the problem of texture stretching.
If you have played some early 3D games dominated by outdoor terrain, such as the uprising, you will find that the ground textures are severely stretched when you encounter steep cliffs. With the introduction of shader and the improvement of graphics card functions, in many recently released high-quality 3D games, Cliff text
