WebeyeX, eyeY and eyeZ are (obviously) the camera position (which you should have already). center X, Y and Z are the positions of the object you want to focus on. upX, upY and upZ are the up vector's coordinates (I seriously have no idea why OpenGL needs this, but I won't argue). This should be 0, 1 and 0 respectively.

Web2 de jun. de 2015 · You need a vector representing the direction you are facing (0,0,-1), one representing upwards (0,1,0) and one vector representing camera position. After rotating the lookat vector you can then translate your position in the direction of the vector. Afterwards you can easily construct the ModelView matrix using the three vectors.

WebOpenGL by itself is not familiar with the concept of a camera, but we can try to simulate one by moving all objects in the scene in the reverse direction, giving the illusion that we are moving. In this tutorial we'll discuss how we can set up a camera in OpenGL. We will discuss an FPS-style camera that allows you to freely move around in a 3D ... Camera position. Getting the camera position is easy. The camera position is a vector in world space that points to the camera's position. We set the camera at the same position we've set the camera in the previous chapter: glm:: vec3 cameraPos = glm:: vec3 ( 0.0f, 0.0f, 3.0f ); Ver mais Swinging the camera around a scene is fun, but it's more fun to do all the movement ourselves!

WebAlso note that in OpenGL (by default, unless you manually build your own projection matrices to do things differently), the camera looks along the negative z axis. If you move the an object forward by the camera's z axis each frame, you'll actually be moving the ball further and further behind the camera, rather than in front of it.
