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.

Qt provides support for integration with OpenGL implementations on all platforms, giving developers the opportunity to display hardware accelerated 3D graphics alongside a more conventional user interface. These examples demonstrate the basic techniques used to take advantage of OpenGL in Qt applications. Documentation for these examples can be found via the Examples link in the main Qt documentation.
