Translate the camera along it's forward axis after rotation in OpenGL?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;

I want to rotate the camera 30° view = glm::rotate(view, glm::radians(-30.0f), glm::vec3(1, 0, 0)); and then move it forward along the new forward axis view = glm::translate(view, glm::vec3(0, 0, 1));. Is this hard to achieve without having to use glm::lookAt function?

Have you tried putting those lines one after the other? If that doesn't work, try applying the transformations in reverse order.

see Understanding 4x4 homogenous transform matrices especially the last sublinks ... you can extract the forward direction directly from camera matrix ... but beware cumulated ModelView matrix is not a camera matrix and also camera matrix is usually inverse ...
