1. Basic concepts of set Introduction: All elements are automatically sorted on insertion Essence: set/multiset is an associative container, and its underlying structure is implemented by binary tree. Difference between set and multiset: set does not allow duplicate elements in the container multiset allows duplicate elements in a contain ...

Last time, we drew a 30 pixel point with vertex shader and fragment shader. This time, we mainly briefly introduced the functions of each shader, the template for detecting OpenGL and GLSL errors, and the template for reading GLSL source code from the file. Finally, we drew a simple two-dimensional animation. 1, Various shader functions Verte ...

1. Constant expression The so-called constant expression refers to an expression composed of multiple (≥ 1) constants. In other words, if the members in the expression are constants, the expression is a constant expression. That is, once the constant expression is determined, its value is not allowed to be changed. The execution proces ...

preface This article uses three examples to explain the single adjustment stack What is a monotone stack The elements in the stack are strictly or non strictly monotonically increasing or decreasing When implementing, maintain the order of elements in the stack Example 1 Acwing1978 (simple) Title Link https://www.acwing.com/problem/content ...

Hash concept Premise: In order structure and balance tree, there is no corresponding relationship between element key and its storage location. Therefore, when looking for an element, it must be compared many times by key. The time complexity of sequential search is O(N), and the height of the tree in the balance tree is O (log n). The ef ...

This article is regarded as the last article [optimization of global registration between G2O and multi view point cloud] Continuation of.As we know from the previous article, we now have the registered global point cloud, the transformation matrix of each point cloud and the RGB image corresponding to each point cloud. Next, it is natural to r ...
