In this work two novel techniques are proposed for 3D lighting computed in real-time on dedicated video hardware (GPU). Classical techniques such as Phong specular reflections are computationally heavy when executed on budget hardware, performing poorly in real-time and reducing battery life. The proposed alternatives are defined in simpler terms yet produce realistically looking results similar to the classical techniques. Numerous experiments are provided implementing the proposed techniques in hardware running both on GPU and CPU. The provided performance benchmarks show that the proposed techniques boost the performance significantly on budget equipment. The experiments were made on many different computers both on 32-bit and 64-bit platforms using single-threaded and multi-threaded approaches to evaluate the real-time performance accurately.
