The article considers modeling method of RAW data received by Lidar in real time as well as its implementation. As the method to determine ranging we consider ray tracing method and the alternative method to determine the ranging using Z-buffer which is often applied while 3D modeling. Mathematical apparatus to estimate the power of reflected radiation is offered. The results of the work show the estimation of the performance to implement the offered method on CPU and GPU performed with the help of OpenGL technology.
