[求助]opengl程序被全屏……

[i=s] 本帖最后由 523066680 于 2010-5-5 22:07 编辑 [/i]

下载了个 opengl源码档案，
这想批量编译来着，结果全部都默认全屏，全屏就算了，还是黑屏，啥效果耶看不见。

我试过了，采用双缓冲的可以保持窗口，而初始化时选择了GLUT_SINGLE 的，编译后都是全屏+黑屏，

当时测试的代码

引用:

#include

#include

static float rotAngle = 0.;

/* Initialize antialiasing for RGBA mode, including alpha
* blending, hint, and line width. Print out implementation
* specific info on line width granularity and width.
*/
void init(void)
{
GLfloat values[2];
glGetFloatv (GL_LINE_WIDTH_GRANULARITY, values);
printf ("GL_LINE_WIDTH_GRANULARITY value is %3.1f\n", values[0]);

glGetFloatv (GL_LINE_WIDTH_RANGE, values);
printf ("GL_LINE_WIDTH_RANGE values are %3.1f %3.1f\n",
values[0], values[1]);

glEnable (GL_LINE_SMOOTH);
glEnable (GL_BLEND);
glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE);
glLineWidth (1.5);

glClearColor(0.0, 0.0, 0.0, 0.0);
}

/* Draw 2 diagonal lines to form an X
*/
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);

glColor3f (0.0, 1.0, 0.0);
glPushMatrix();
glRotatef(-rotAngle, 0.0, 0.0, 0.1);
glBegin (GL_LINES);
glVertex2f (-0.5, 0.5);
glVertex2f (0.5, -0.5);
glEnd ();
glPopMatrix();

glColor3f (0.0, 0.0, 1.0);
glPushMatrix();
glRotatef(rotAngle, 0.0, 0.0, 0.1);
glBegin (GL_LINES);
glVertex2f (0.5, 0.5);
glVertex2f (-0.5, -0.5);
glEnd ();
glPopMatrix();

glFlush();
}

void reshape(int w, int h)
{
glViewport(0, 0, w, h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
if (w <= h)
gluOrtho2D (-1.0, 1.0,
-1.0*(GLfloat)h/(GLfloat)w, 1.0*(GLfloat)h/(GLfloat)w);
else
gluOrtho2D (-1.0*(GLfloat)w/(GLfloat)h,
1.0*(GLfloat)w/(GLfloat)h, -1.0, 1.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}

void keyboard(unsigned char key, int x, int y)
{
switch (key) {
case 'r':
case 'R':
rotAngle += 20.;
if (rotAngle >= 360.) rotAngle = 0.;
glutPostRedisplay();
break;
case 27: /* Escape Key */
exit(0);
break;
default:
break;
}
}

/* Main Loop
* Open window with initial window size, title bar,
* RGBA display mode, and handle input events.
*/
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize (200, 200);
glutCreateWindow (argv[0]);
init();
glutReshapeFunc (reshape);
glutKeyboardFunc (keyboard);
glutDisplayFunc (display);
glutMainLoop();
return 0;
}

当时执行批量编译的.sh[code]
#!/bin/bash
for i in `ls *.c`
do
echo -n -e "\nPress any key to continue..."
read -s -n1 inp
read -t0.1 -n10 REPLY
if [ "$inp" == "q" ] ;then exit ;fi
gcc -o ${i/".c"/""} -lglut $i
echo -n -e "\n\E[1;32;40m"
./${i/".c"/""}
echo -n -e "\E[0;38;40m"
done
