Web31 de jul. de 2015 · 1 Using OpenGL and the GLM matrix library, I want to translate my camera relative to the world coordinate system. This requires me to compute the necessary view matrix. To initialise the view matrix, I used: view_matrix = glm::lookAt (eye, centre, up); Where eye = (0, 0, 10), centre (0, 0, 0), and up = (0, 1, 0). 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. graphic buyWebIn this video I'm going to show you how to implement the spot light effect in OpenGL.

You compute both your normal and view vector correctly in view space in order to perform your lighting computations in view space. So you need your normalized light direction in view space, too. chip\u0027s 6pWebeyeX, 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).
