We consider the cascade initiated by high energy electrons or γ-rays in the radiation field of the massive star in Cen X-3. The spectra of cascade γ-rays, which escape from the system and collide with a surface of the massive star, are computed for different viewing angles. They have different shapes and intensities. We predict the γ-ray light curves at energies above 100 MeV and 300 GeV from the Cen X-3 system. Photons falling onto the massive star should excite γ-ray lines. However we show that the phase distribution of the γ-ray line and the continuum γ-ray emission is different. This feature can be used as a good test of our model by future γ-ray observations in the MeV, GeV and TeV energy ranges. .
