java - OpenGL中带有四边形的奇怪条带

Question

一切都在我刚刚拍摄的屏幕截图上......基本上，即使没有启用照明，它也会这样做......它是否与抗锯齿有关？

@Axel，这是我的单个立方体的代码：

glBegin(GL_QUADS);

glColor3f(r,g,b);

glNormal3f(0, 0, -1);
glVertex3f(position.x + radius, position.y + radius, position.z - radius);
glVertex3f(position.x + radius, position.y - radius, position.z - radius);
glVertex3f(position.x - radius, position.y - radius, position.z - radius);
glVertex3f(position.x - radius, position.y + radius, position.z - radius);

glNormal3f(0, 0, 1);
glVertex3f(position.x + radius, position.y + radius, position.z + radius);
glVertex3f(position.x + radius, position.y - radius, position.z + radius);
glVertex3f(position.x - radius, position.y - radius, position.z + radius);
glVertex3f(position.x - radius, position.y + radius, position.z + radius);

glNormal3f(-1, 0, 0);
glVertex3f(position.x - radius, position.y + radius, position.z + radius);
glVertex3f(position.x - radius, position.y - radius, position.z + radius);
glVertex3f(position.x - radius, position.y - radius, position.z - radius);
glVertex3f(position.x - radius, position.y + radius, position.z - radius);

glNormal3f(1, 0, 0);
glVertex3f(position.x + radius, position.y + radius, position.z + radius);
glVertex3f(position.x + radius, position.y - radius, position.z + radius);
glVertex3f(position.x + radius, position.y - radius, position.z - radius);
glVertex3f(position.x + radius, position.y + radius, position.z - radius);

glNormal3f(0, -1, 0);
glVertex3f(position.x + radius, position.y - radius, position.z + radius);
glVertex3f(position.x - radius, position.y - radius, position.z + radius);
glVertex3f(position.x - radius, position.y - radius, position.z - radius);
glVertex3f(position.x + radius, position.y - radius, position.z - radius);

glNormal3f(0, 1, 0);
glVertex3f(position.x + radius, position.y + radius, position.z + radius);
glVertex3f(position.x - radius, position.y + radius, position.z + radius);
glVertex3f(position.x - radius, position.y + radius, position.z - radius);
glVertex3f(position.x + radius, position.y + radius, position.z - radius);

glEnd();
