Our team made a promotional 3D animation of a security net product, explaining the operation method and assembly in underground mining excavations for CARBOSPEC M.Jaśniok Spółka Jawna . 3D animation was prepared for the trade fair event which was theInternational Fair of Mining and Power Industry and Metallurgy “Katowice 2017” and for the needs of business meetings. The film material has been prepared in several graphic versions and as short animation forms dedicated to individual stages of product assembly. In the animation we used a variety of 3D models of mining as well as auxiliary equipment. Thanks to our experience, 3D animation was implemented during 30 days during the holidayseason, equipping Carbospec in an effective marketing tool.
