OpenGL glEnable Depth Test

Shows how to turn on the depth test (z test) using glEnable(GL_DEPTH_TEST) to enable a write to the depth buffer (z-buffer). You must sort your geometry in the Z dimension. Also shows clearing the depth buffer using glClear(GL_DEPTH_BUFFER_BIT) and how these operations affect what is rendered to the screen.

[@MrSaemichlaus]

1:55 who paused the video? Guys, come on :D

[@JamieKingCS]

Hehe. Did you? You better have!

[@MrSaemichlaus]

No time for pausing, I'm searching for help, good sir :D I can't get gluPerspective() to work...no clipping lanes, picture has wrong aspect ratio. Have been searching for days, aargh :(

[@JamieKingCS]

Yikes. Fixed function pipeline huh?

[@MrSaemichlaus]

No idea...I checked an example that comes with my IDE, that gave my program a blackout :) I guess the headerfiles are complete, libs and bins included and linked. Btw, I'm a freetime programmer, so ... xD But man, that's probably the biggest knot I've ever had in coding...

[@JamieKingCS]

Ya, sounds like you are doing fixed function. That's deprecated. Good to learn, but not if it's worth it.
