计算机图形学 -- 变换之旋转二 [鼠标操作]

本文主要是介绍计算机图形学 -- 变换之旋转二 [鼠标操作]，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在上一次的旋转中加入鼠标的动作，

按左键加速，右键减速，中键停止

滚轮的动作文件中好像没有，总之没有找到，只有键的定义

稍后补上

#include<GL/glut.h>
#include<stdlib.h>
#pragma comment(linker,"/subsystem:\"windows\" /entry:\"mainCRTStartup\"") 
GLfloat rtri;
float add = 0.1f;void init()
{glClearColor(0.0f,0.0f,0.0f,0.0f);glShadeModel(GL_SMOOTH);	//GL_FLAT和GL_SMOOTH在这里的区别很明显哟glEnable(GL_DEPTH_TEST);}void mydisplay()
{glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);glLoadIdentity();glTranslatef(0.0f,0.2f,-4.0f);	glRotatef(rtri,0.0f,1.0f,0.0f);	glBegin(GL_TRIANGLES);glColor3f(1.0f,0.0f,0.0f);glVertex3f(0.0f,1.0f,0.0f);glColor3f(0.0f,1.0f,0.0f);glVertex3f(-1.0f,-1.0f,1.0f);glColor3f(0.0f,0.0f,1.0f);glVertex3f(1.0f,-1.0f,1.0f);glColor3f(1.0f,0.0f,0.0f);glVertex3f(0.0f,1.0f,0.0f);glColor3f(1.0f,0.0f,1.0f);glVertex3f(1.0f,-1.0f,1.0f);glColor3f(0.0f,1.0f,0.0f);glVertex3f(1.0f,-1.0f,-1.0f);glColor3f(1.0f,0.0f,0.0f);glVert
