USING BLENDER 3D FOR LEARNING VIRTUAL AND MIXED REALITY

In this contribution we are focusing on creation of mixed reality composed of panoramatic video, into which an animation of 3D model of object is added. In the research conducted at Department of Computer Science, Faculty of Natural Sciences at Matej Bel University in Banska Bystrica (Slovakia) we are dealing with the question how is it possible to create the desired environment as quickly and efficiently as possible, into which we can set an animated object. If this environment is sufficiently realistic and man can freely rotate and move there at the same time, the deception of senses occurs. Knowing that, it is possible to use such environment for the treatment of different phobias and insert an object model whose motion and trajectory can be predefined. In case of arachnophobia for example, it would be a spider, etc. The paper deals with detailed steps how to create such a combination using the Blender 3D software tools such as positioning and tracking of tags, setting camera parameters, calculating its motion, setting a scene in 3D space, importing a 3D model into a scene, using rendering tools, lighting a scene, combining images into a single unit, etc.
