Thread: Rotating In OpenGL

Use glRotate3f(), glTranslate3f(), etc.

glRotate*() and glTranslate*() functions modify the location of objects in the world relative to a stationary camera. So instead of moving the actual camera around the world, it will move the world around the camera. If you wanted this same effect but on the camera you would use the gluLookAt() function. The following code is an example from my book to help explain this more:

Code:

void PlaneView(GLfloat planeX, glfloat planeT, GLfloat planeZ, GLfloat roll, GLfloat pitch, GLfloat yaw)
{
	//roll is rotation on the z axis
	glRotatef(roll, 0.0f, 0.0f, 1.0f);

	//yaw (heading) is y rotation
	glRotatef(yaw, 0.0f, 1.0f, 0.0f);

	//pitch is rotation on x
	glRotatef(pitch, 1.0f, 0.0f, 0.0f);

	//move the plane to the planes world coordinates
	glTranslatef(-planeX, -planeY, -planeZ);
}

When u picture this in use, imagine being in the piolet seat.
