opengl实现3D弹球
实现在3D空间小球的运动，碰到墙壁后反弹，小球会自己旋转和移动，运用了opengl,开发语言运用的是c#,框架运用的是taoframework.代码如下：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using Tao.OpenGl;using Tao.FreeGlut;namespace homework2{ public partial class Form1 : Form { double cx = 0.01, cy = 0.02, cz = 0.03; double x = 0.0, y = 0.0, z = 0.0; double angle = 2.0; double radius = 0.1; public Form1() { InitializeComponent(); this.simpleOpenGlControl1.InitializeContexts(); Glut.glutInit(); } private void MyInit() { Gl.glClearColor(0.0f, 0.0f, 0.0f, 1.0f); } private void SetViewVolume() { Gl.glMatrixMode(Gl.GL_PROJECTION); Gl.glLoadIdentity(); double aspect = (double)this.simpleOpenGlControl1.Width / (double)this.simpleOpenGlControl1.Height; Glu.gluPerspective(45, aspect, 0.1, 100.0); Gl.glViewport(0, 0, this.simpleOpenGlControl1.Width, this.simpleOpenGlControl1.Height); } private void simpleOpenGlControl1_Load(object sender, EventArgs e) { MyInit(); SetViewVolume(); } private void simpleOpenGlControl1_Paint(object sender, PaintEventArgs e) { Gl.glClear(Gl.GL_COLOR_BUFFER_BIT); drawWall(); Gl.glMatrixMode(Gl.GL_MODELVIEW); Gl.glLoadIdentity(); Glu.gluLookAt(0.0, 0.0, 3.5, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0); Gl.glPushMatrix(); Gl.glColor3f(1.0f, 1.0f, 1.0f); Gl.glTranslated(x, y, z); Gl.glRotated(angle, 0.0, 1.0, 0.0); Glut.glutWireSphere(0.1, 20, 20); Gl.glPopMatrix(); } private void drawWall() { Gl.glMatrixMode(Gl.GL_MODELVIEW); Gl.glLoadIdentity(); Gl.glPushMatrix(); Glu.gluLookAt(0.0, 0.0, 3.5, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0); Gl.glBegin(Gl.GL_QUADS); Gl.glColor3f(0.0f, 0.0f, 1.0f); Gl.glVertex3f(1.0f, 1.0f, 1.0f); Gl.glVertex3f(-1.0f, 1.0f, 1.0f); Gl.glVertex3f(-1.0f, -1.0f, 1.0f); Gl.glVertex3f(1.0f, -1.0f, 1.0f); Gl.glEnd(); Gl.glBegin(Gl.GL_QUADS); Gl.glColor3f(1.0f, 0.0f, 0.0f); Gl.glVertex3f(1.0f, -1.0f, -1.0f); Gl.glVertex3f(-1.0f, -1.0f, -1.0f); Gl.glVertex3f(-1.0f, 1.0f, -1.0f); Gl.glVertex3f(1.0f, 1.0f, -1.0f); Gl.glEnd(); Gl.glBegin(Gl.GL_QUADS); Gl.glColor3f(0.0f, 1.0f, 0.0f); Gl.glVertex3f(-1.0f, 1.0f, 1.0f); Gl.glVertex3f(-1.0f, 1.0f, -1.0f); Gl.glVertex3f(-1.0f, -1.0f, -1.0f); Gl.glVertex3f(-1.0f, -1.0f, 1.0f); Gl.glEnd(); Gl.glBegin(Gl.GL_QUADS); Gl.glColor3f(0.0f, 1.0f, 0.0f); Gl.glVertex3f(1.0f, 1.0f, -1.0f); Gl.glVertex3f(1.0f, 1.0f, 1.0f); Gl.glVertex3f(1.0f, -1.0f, 1.0f); Gl.glVertex3f(1.0f, -1.0f, -1.0f); Gl.glEnd(); Gl.glPopMatrix(); } private void timer1_Tick(object sender, EventArgs e) { angle += 3.0; if (x+radius >= 1||x-radius<=-1) cx = -cx; if (y+radius >= 1 || y-radius <= -1) cy = -cy; if (z+radius >=1 || z-radius <= -1) cz = -cz; x += cx; y +=cy; z += cz; this.simpleOpenGlControl1.Refresh(); } }}
