前言

在openGL绘制字体，我们一般都使用freeType字体库，如下图所示

下载

freeType官网

编译源码

使用CMake编译源码

如果嫌麻烦，我这里有编译好的库，包括头文件、lib静态库、dll动态库

编译好的lib和dll库下载地址

例子

// Hacky test//#include "glfreetype/TextRenderer.hpp"
#include "TextRenderer.hpp"
#include "GLFW/glfw3.h"int main(int argc, char **argv)
{GLFWwindow* window;/* Initialize the library */if (!glfwInit()) {return -1;}glfwWindowHint(GLFW_SAMPLES, 4);int windowWidth = 300;int windowHeight = 40;window = glfwCreateWindow(windowWidth, windowHeight, "glfreetype test", NULL, NULL);if (!window) {glfwTerminate();return -1;}/* Make the window's context current */glfwMakeContextCurrent(window);// NEHE's font systemglfreetype::font_data our_font;//font_dataour_font.init("C:/Windows/Fonts/Arial.ttf", 25 /* size */);/* Loop until the user closes the window */while (!glfwWindowShouldClose(window)) {/* Render here */glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);glClearColor(255.0, 255.0, 255.0, 0.0);glPushMatrix();glLoadIdentity();// Blue textglColor3ub(0,0,0xff);glfreetype::print(our_font, 20 /* xpos */, 20 /* ypos */, "The quick brown fox blah blah blah");glPopMatrix();/* Swap front and back buffers */glfwSwapBuffers(window);/* Poll for and process events */glfwPollEvents();}our_font.clean();glfwTerminate();return 0;
}
