• Problem enabling OpenGL ES depth test on iPhone. What steps are necessary?

  - by Chris Cooper

  I remember running into this problem when I started using OpenGL in OS X. Eventually I solved it, but I think that was just by using glut and c++ instead of Objective-C... The lines of code I have in init for the ES1Renderer are as follows: glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LEQUAL); Then in the render method, I have this: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); I assume I'm missing something specific to either the iPhone or ES. What other steps are required to enable the depth test? Thanks

  - by Liuyi Sun

  Hi, guys, I've been developing an iphone web application for a while, and encountered a weird problem: when open the web app in safari(with safari chrome, not starting it from home screen), safari can generate proper "If-Not-Modified-Since" and "If-None-Matches", so the server simply gives 304 Not Modified to speed up the process. however, when starting the app from home screen, safari seems to forget these two headers, and server always replies with 200 OK... any ideas for this?
