JOGL测试

JOGL是JAVA通过JNI的方式调用OpenGL的封装。

给出一个简单Demo(所需依赖，不是最小依赖，有多余的jar和DLL)

1、环境配置

依赖jar包：

指定native库

工程配置和javacv配置过程类似：指定依赖的jar包、dll库。

2、使用JOGL显示三角形

公共类：OneTriangle，进行OpenGL的初始化、绘图。

import com.jogamp.opengl.GL;import com.jogamp.opengl.GL2;import com.jogamp.opengl.glu.GLU;public class OneTriangle {    //初始化    protected static void setup( GL2 gl2, int width, int height ) {        gl2.glMatrixMode( GL2.GL_PROJECTION );        gl2.glLoadIdentity();        // coordinate system origin at lower left with width and height same as the window        GLU glu = new GLU();        glu.gluOrtho2D( 0.0f, width, 0.0f, height );        gl2.glMatrixMode( GL2.GL_MODELVIEW );        gl2.glLoadIdentity();        gl2.glViewport( 0, 0, width, height );    }    //渲染    protected static void render( GL2 gl2, int width, int height ) {        gl2.glClear( GL.GL_COLOR_BUFFER_BIT );        // draw a triangle filling the window        gl2.glLoadIdentity();        //绘制图元：三角形        gl2.glBegin( GL.GL_TRIANGLES );        //第一个点以及颜色        gl2.glColor3f( 1, 0, 0 );        gl2.glVertex2f( 0, 0 );        //第二个点以及颜色        gl2.glColor3f( 0, 1, 0 );        gl2.glVertex2f( width, 0 );        //第三个点以及颜色        gl2.glColor3f( 0, 0, 1 );        gl2.glVertex2f( width / 2, height );        gl2.glEnd();    }}

OneTriangleSwingGLCanvas：显示三角形

package com.test;import java.awt.BorderLayout;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;import javax.swing.JFrame;import com.jogamp.opengl.GLAutoDrawable;import com.jogamp.opengl.GLCapabilities;import com.jogamp.opengl.GLEventListener;import com.jogamp.opengl.GLProfile;import com.jogamp.opengl.awt.GLCanvas;public class OneTriangleSwingGLCanvas {    public static void main( String [] args ) {        GLProfile glprofile = GLProfile.getDefault();        GLCapabilities glcapabilities = new GLCapabilities( glprofile );        final GLCanvas glcanvas = new GLCanvas( glcapabilities );//添加监听        glcanvas.addGLEventListener( new GLEventListener() {                        @Override            public void reshape( GLAutoDrawable glautodrawable, int x, int y, int width, int height ) {                OneTriangle.setup( glautodrawable.getGL().getGL2(), width, height );            }                        @Override            public void init( GLAutoDrawable glautodrawable ) {            }                        @Override            public void dispose( GLAutoDrawable glautodrawable ) {            }                        @Override            public void display( GLAutoDrawable glautodrawable ) {//调用渲染方法，进行渲染                OneTriangle.render( glautodrawable.getGL().getGL2(), glautodrawable.getSurfaceWidth(), glautodrawable.getSurfaceHeight() );            }        });//创建绘图窗口        final JFrame jframe = new JFrame( "JAVA下的OpenGL实现" );         jframe.addWindowListener( new WindowAdapter() {            public void windowClosing( WindowEvent windowevent ) {                jframe.dispose();                System.exit( 0 );            }        });//将GL渲染的图，显示到窗口中        jframe.getContentPane().add( glcanvas, BorderLayout.CENTER );        jframe.setSize( 640, 480 );        jframe.setVisible( true );    }}
