Abstract: Computer graphics methods and algorithms serve to create virtual reality - it means to artificial images of non existing scene. Methods and algorithms of radiative heat exchange serve to determination of temperature and power flow in heat systems, in which radiative heat exchange has occurred. In computer graphics light is modeling and tracing, in radiative heat exchange – heat radiation is testing. Both, light and heat radiation are EM waves. Physical lows of generation, propagation, reflection or absorption in those both cases are the same. But the description of those phenomena for computer graphic and for radiative heat transfer are partially different. It came from the others assumptions in both cases and from the others expectation in final result of calculations. In this lecture the comparison between both cases will be done. The similarities and the differences in:

- description of light and heat radiation phenomena,
- description of light systems and radiative heat transfer systems,
- expected results of calculations,
- acceptable assumptions,
- methods and algorithms of calculations
will be specified.

Additionally, possibility of using computer graphics methods and algorithms (also programs and software) to calculation of radiative heat exchange system will be presented.
