WebBut as for your actual issue, it has as much to do with how your traslating as rotating. Try this: add glutWireCube (1); at random points in your code. That will tell you a lot about your current model-view matrix and let you debug it easier. For example, right before your DrawRobot in display. Have you taken matrix math classes? Web23 de dez. de 2024 · I have tried using the hidden MarkerHandle settings as described here and it works brilliantly with the exception that transparency is only binary for markers of the '.' type (i.e. the only alpha value that affects the graph is 0, in which case the point is un-rendered), unless the marker size is > 15, in which it seems that a different openGL … cs6 nedir
opengl - How to rotate an object around a fixed point?
http://www.opengl-tutorial.org/intermediate-tutorials/tutorial-17-quaternions/ WebFrom your code it looks as though your camera is stationary (cam_position doesn't change) and you just change cam_target. This will have the effect of spinning your camera around on the spot. If the only thing in your scene is your terrain then it might appear as though the terrain is rotating around the camera. WebIf you want to rotate around another point: rotated_point = origin + (orientation_quaternion * (point-origin)); How do I interpolate between 2 quaternions ? This is called a SLERP: Spherical Linear intERPolation. With GLM, you can do this with mix: glm::quat interpolatedquat = quaternion::mix(quat1, quat2, 0.5f); // or whatever factor dynaread scam
