i’m trying to draw two cylinder, both filled with the same texture, but I have managed to draw only the first one, here is my draw func:
void display(void)
{
// Projection plane
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
//a->draw(mouseY);
//draw first cylinder WORKING
glPushMatrix();
glRotatef(mouseY, 0, 0, 1);
quadratic = gluNewQuadric();
gluQuadricNormals(quadratic, GLU_SMOOTH);
gluQuadricTexture(quadratic, GL_TRUE);
glMatrixMode(GL_TEXTURE);
glLoadIdentity();
glRotatef(90,0,0,1);
glTranslatef(0,-1.0,0);
glMatrixMode(GL_PROJECTION);
gluCylinder(quadratic,fh_cyl,fh_cyl,fw_cyl,50,1000);
if(!exec) //used only one time to get a visible cylinder
{
glTranslatef(fX_cylpos,fY_cylpos,0);
glRotatef(90, 0.0, 1, 0.0); //rotate object 90° on Y axis
glRotatef(fangle_cyl, 1.0, 0.0, 0.0); //0° = vertical / 90° = horizontal
exec=true;
}
glPopMatrix();
glPushMatrix();
//draw second cylinder NOT WORKING
glRotatef(mouseY, 0, 0, 1);
quadratic2 = gluNewQuadric();
gluQuadricNormals(quadratic2, GLU_SMOOTH);
gluQuadricTexture(quadratic2, GL_TRUE);
gluCylinder(quadratic2,fh_cyl,fh_cyl,fw_cyl,50,1000);
if(!exec2)
{
glTranslatef(fX_cylpos+200,fY_cylpos,0);
glRotatef(90, 0.0, 1, 0.0); //rotate object 90° on Y axis
glRotatef(fangle_cyl, 1.0, 0.0, 0.0); //0° = vertical / 90° = horizontal
exec2=true;
}
glPopMatrix();
//b->draw(mouseY);
glutSwapBuffers();
}
And this is the reshape func:
void reshape(int w, int h)
{
glViewport (0, 0, (GLsizei) w, (GLsizei) h);
glLoadIdentity();
glMatrixMode(GL_PROJECTION);
//glOrtho(-1000.0, 1000.0*(screen_h/screen_w), -1000.0, 1000.0*(screen_h/screen_w), 1000.0, -110.0);
glOrtho(fOrtoXinit, fOrtoXend, fOrtoYinit, fOrtoYend , 1000, -1000.0);
glMatrixMode(GL_MODELVIEW);
}
the code in the if statement is used to draw the cylinder vertical.
