The square root of a sum of squares is easier to read and should be computed more accurately if done for us by hypot(). Variables set only once should be set as an initializer and declared const, to make clear this is what's happening. Loop variables can be local to loops. Adding a value to, or subtracting one from, a multiple of itself just multiplies it be one plus (or minus) the multiplier; assigning the result to the same variable is clearer as a *= (especially when the factors are now overt numeric constants). An array of 16k floats all updated in locksteck to the same value can be replaced by a single float that holds that value. Simple things should not be needlessly made more complicated - especially in example code, which should be pedagogic.

README
This directory contains legacy examples that use the fixed pipeline and thus are not compatible with OpenGL ES 2.0+ and the core profile of OpenGL 3.0+. They also rely on the Qt OpenGL module (e.g. QGLWidget) which is not advisable in new application.
