We report results of the first analysis of collisions between stable fundamental (alias spinless) and vortical (spinning) three-dimensional dissipative solitons in a model of a laser cavity. The systematic analysis is carried out for values S = 1 and S = 2 of the vorticity of the latter soliton. With the increase of the collision momentum, χ1, the same generic scenarios are observed in either case: merger into a single fundamental soliton at both small and relatively large values of χ1, and the formation of two fundamental solitons in an intermediate interval of variation of the collision momentum χ1. At very large values of χ1, the collision seems quasi-elastic, but the vortex soliton eventually splits into two nonspinning fragments.
