分享用了两次glPolygonMode()会出现什么结果？
void DrawPolygons()
{
glLineWidth(2.0f);
glPolygonMode(GL_FRONT,GL_LINE);
glPolygonMode(GL_BACK,CL_FILL);
glFrontFave(GL_CCW);
glBegin(GL_POLYGON);
glVertex(-0.3f,0.3f);
glVertex(-0.7f,-0.20f)
glVertex(-0.3f,-0.40f;
glVertex(0.4f,-0.40f);
glVertex(0.8f,-0.2f);
glVertex(0.4f,0.3f);
glEnd();
}
{
glLineWidth(2.0f);
glPolygonMode(GL_FRONT,GL_LINE);
glPolygonMode(GL_BACK,CL_FILL);
glFrontFave(GL_CCW);
glBegin(GL_POLYGON);
glVertex(-0.3f,0.3f);
glVertex(-0.7f,-0.20f)
glVertex(-0.3f,-0.40f;
glVertex(0.4f,-0.40f);
