run on device about xbpagecurl

[xissburg]

THanks for opening this issue. I tested it and indeed doesn't work on the iPad 1, but I am not getting any errors here. It just stops rendering. After analyzing the code a little, I found that whenever I call normalize or length in the fragment shader (FragmentShader.glsl) to normalize the normal vector, the OpenGL view doesn't render anything> I will look further into this mysterious bug.

help me plz plz plz :(

[xissburg]

Sorry for the delay. A temporary fix would be to, in the FragmentShader.glsl file, exchange the line vec3 n = normalize(v_normal); by vec3 n = v_normal;.
