直接上完整代码：#define GLEW_STATIC#define STB_IMAGE_IMPLEMENTATION#include<iostream>#include<GL/glew.h>#include<GLFW/glfw3.h>#include"Shader.h"#include "stb_image.h"#include <glm.hpp>#include <gtc/matrix_transform.hpp>#inc

MVP变换M变换是将物体空间的坐标转换到世界空间坐标的一个过程，可以有旋转平移缩放等操作V变换是用来将世界坐标变换到观察空间，一般为平移操作P变换指透视投影变换定义三个矩阵，分别代表MVP矩阵： glm::mat4 modelMat; modelMat = glm::rotate(modelMat, glm::radians(-60.0f), glm::vec3(1.0f, 0.0f, 0.0f)); //绕x轴顺时针旋转60度 glm::mat4 viewMat; viewMa

矩阵变换在顶点着色器中添加一个变换矩阵transform，用矩阵uniform乘以位置向量#version 330 core layout (location = 7) in vec3 aPos; layout (location = 8) in vec3 aColor; layout (location = 9) in vec2 aTexCoord; out vec4 vertexColor; out vec2 TexCoord;uniform ma

为了能够让笑脸图片重叠到箱子图片上做如下修改：fragmentSource.txt#version 330 core in vec4 vertexColor; in vec2 TexCoord;uniform sampler2D ourTexture;uniform sampler2D ourFace; //加入第二张图片out vec4 FragColor; void main(){ // FragColor = vert

1. 下载stb_image.h编写格式（在main.cpp中）：#define STB_IMAGE_IMPLEMENTATION#include "stb_image.h"2.修改着色器vertexSource.txt#version 330 core layout (location = 7) in vec3 aPos; layout (location = 8) in vec3 aColor; layout (location = 9) in vec

Shader.h 中声明新函数：private: void checkCompileErrors(unsigned int ID, std::string type);Shader.cpp 中定义新函数：void Shader::checkCompileErrors(unsigned int ID, std::string type){ int success; char infolog[512]; if (type != "PROGRAM") { glGetShaderiv(ID,

main函数#define GLEW_STATIC#include<iostream>#include<GL/glew.h>//#include<glad/glad.h>#include<GLFW/glfw3.h>#include"Shader.h"//现在直接在顶点数据里加入颜色信息float vertices[] = {-0.5f, -0.5f, 0.0f,1.0f,0.0f,0.0f,//右上角0 0.5f, -0.5f,

新加项Shader.h#pragma once#include<string>class Shader{public: Shader(); Shader(const char * vertexPath, const char * fragmentPath); //cpu中的string 和 char* std::string vertexString; std::string fragmentString; const char* vertexSource; con.

修改部分：着色器中定义颜色信息：const char* vertexShadersource ="#version 330 core \n""layout (location = 7) in vec3 aPos; \n""layout (location = 8) in vec3 aColor; \n" //加入颜色属性位置是8;"out vec4 vertexColor; \n" //在 vertexShadersource 中定义并输出到fragment

重点部分：在顶点着色器中定义一个out扔到片段着色器中（in），片段着色器将顶点着色器中vertexColor的值赋给每一个像素；#mermaid-svg-DlLweXvQF1RV2pxB .label { font-family: 'trebuchet ms', verdana, arial; font-family: var(--mermaid-font-family); fill: #333; color: #333; }#mermaid-svg-DlLweXvQF1R

OpenGL三角形绘制具体流程：版本号初始化glew将着色器附加到程序对象上初始化窗口创建窗口定义VBO VAO EBO创建着色器并编译创建程序对象绘制#define GLEW_STATIC#include<iostream>#include<GL/glew.h>//#include<glad/glad.h>#include<GLFW/glfw3.h>float vertices[] = {-0.5f, -0.5f, 0.0f,
