OpenGL绘制上坡的路
这个是直路 怎么改成上坡的路

C/C++ code

for(float z=1200;z>-100;z-=25){        glBindTexture(GL_TEXTURE_2D, texture[1]);//跑道        glBegin(GL_QUADS);        glTexCoord2f(0,0); glVertex3f(-9,2,z);        glTexCoord2f(1,0); glVertex3f(9,2,z);        glTexCoord2f(1,1); glVertex3f(9,2,z-25);        glTexCoord2f(0,1); glVertex3f(-9,2,z-25);        glEnd();
