OpenGL [Episode 31] Building The View Matrix with glm::lookat (and moving forward and backwards)

►Lesson Description: In this lesson we introduce a small abstraction for creating a camera using glm's lookAt matrix. We then implement the ability to move forward and backwards in our camera. I leave you at a cliff hanger to think about how to otherwise implement first person camera.

Just finishing the current playlist. Feeling like Hideo Kojima already.

Perhaps we should rename g_uOffset and g_uRotate. they're not uniforms anymore. g_offset and g_rotate would be fine.

[@MikeShah]

Agreed, that's probably not a bad idea :)

Whenever my camera's z position is less than 0, it horseshoe's back around moving in a positive direction. Any idea what the issue could be? Also i'm following along in C so the code below is a bit different.

For anyone having this problem, I'm pretty sure mike did this on purpose. I've watched the video and followed everything to the letter. The issue still persists and I'm pretty sure he knows why cause I think I can see him trying to move the quad in such a way that its hard to tell the bug is happening. I also noticed he doesn't move left or right at all in the video. Whenever I do, my camera spirals along the z axis. He was right. There's definitely a better way to do this lol.

@@Beholden28 Will be fixed in the next video :) This behavior was done on purpose to give folks some time to think about it (You'll see me make an update to glm::lookat in the upcoming videos, as well as implement left and right)
