•Full-field strain and strain-rate fields of rock was obtained by high-speed 3D-DIC.•The 256 × 256 pixels and 200,000 fps are suggested in dynamic measurement of rock.•Wave propagation, dispersion and radial inertial effect on the specimen were found.•The comparison was conducted between 2D- and 3D-...
