2D rotation map realizes skinning and bone dressing

First you need to know how to rotate 2D graphics. Achieve costume changes through 2D rotation maps, skinned mesh renderers and merged bones. The first is the association between the 2D rotation map and the skinning script, the changeAvator.Change() method in the code below. using System; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems; using […]

Application of C++ algorithm prefix sum: the principle, source code and test cases of the highest-scoring minimum rotation

Basic knowledge points involved in this article C++ algorithm: principles, source code and test cases of prefix sum, prefix product, prefix XOR including course videos Title Given an array nums, we can rotate it by a non-negative integer k, so that the array becomes [nums[k], nums[k + 1], … nums[nums.length – 1], nums [0], nums[1], […]

android pointer animation rotation

Record a simple animation Rendering: They are all implemented directly using the image resource FrameLayout layout. The layout is as follows: <LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” xmlns:tools=”http://schemas.android.com/tools” android:layout_width=”match_parent” android:layout_height=”match_parent” android:orientation=”vertical” > <TextView android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:layout_marginStart=”22dp” android:layout_marginTop=”16dp” android:text=”Manager” android:textColor=”#010101″ android:textSize=”22sp” /> <FrameLayout android:layout_width=”match_parent” android:layout_height=”wrap_content” > <FrameLayout android:layout_width=”match_parent” android:layout_height=”wrap_content” android:layout_marginHorizontal=”22dp”> <ImageView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:scaleType=”fitXY” /> <ImageView android:layout_width=”274dp” android:layout_height=”137dp” android:layout_marginTop=”34dp” […]

Transformation matrix of points in 2D coordinate system (translation, scaling, rotation, miscut)

This article reprints the article of the same name written by Zhuo Bufan on Zhizhihu. I have run the code described in it and added some comments to make it easier to understand. 1. Translation In 2D space, we often need to translate a point to another position. Assume a point P in space, expressed […]

c++ visual processing—functions of affine transformation and two-dimensional rotation transformation matrix

Affine transformationcv::warpAffine cv::warpAffine is a function in OpenCV used to perform affine transformation. An affine transformation is a linear transformation that can be used to perform operations such as translation, rotation, scaling, and shearing. The following is the basic usage of the cv::warpAffine function: cv::warpAffine(src, dst, M, dsize, flags, borderMode, borderValue); src: Input image. dst: […]

uCOSIII real-time operating system 5 task API (time slice rotation API scheduling)

Time slice rotation scheduling Time slice rotation method: mainly used for process scheduling in time-sharing systems. In order to implement round-robin scheduling, the system arranges all ready processes into the first process of a queue according to the first-in, first-out principle, and allows the CPU to run for a time slice. A time slice is […]
