Interactive application
replaces animal experiments

About the project

At the request of a Medical University we created fully interactive training applications that provide students with the possibility of experimenting on a three-dimensional frog, rat or a rabbit during virtual classes. Moreover, thanks to special glasses we have an illusion of three-dimensional image depth that makes the experiments more realistic and allows to gain the same knowledge as in a real laboratory session – but without harming the animals.

Case study

A doctor operating on a patient cannot afford a mistake. For many years students have spent hours in laboratories learning the basics of the trade and practicing manual skills. The objects of these experiments were often animals. But due to ethical aspects and financial cutbacks made by many facilities it becomes significantly harder to show students the basic reactions and physiological reflexes that occur in an animal organism. What used to be a standard practice is now restricted by EU permissions and additional constrains. But luckily the progress was made also in technology. Photorealistic 3D graphics prepared in Quazar3D allows not only to show the smallest details of the anatomy and complex physiological processes, but also to interact with the model in a way that is similar to the actual procedure. Why kill animals, when we can use virtual technology?


Coming across the needs of modern education systems, i3D developed set of interactive experiments, which until now could not be performed without the use of laboratory animals. ePhysiology project covers full program of laboratory exercises used in physiology and anatomy courses at universities. In virtual world we can observe how animals are prepared for the experiments, starting from anesthesia through uncovering or isolation of organs, to connecting them to professional equipment.

The set of exercises contains nervous, muscular, and cardiovascular system examination and observation of body’s reactions to many substances – the user feels as if he stood at an operating table. And it’s just the beginning. The wide range of exercises guarantees diverse experiences that teach the student to make right decisions in the future. For example, when experimenting on frog’s heart, we check the influence of temperature, adrenaline, acetylcholine, potassium, calcium, vagus nerve stimulation, pre-load and after-load on heart contractions. Experiment on rabbit lets us observe changes in blood pressure, breathing and heart rate after administration of adrenaline, acetylcholine and ammonia or vagus nerve stimulation/transection and occlusion of renal arteries. The choice of the program lies entirely on the student and the professor. Such virtual exercises can be paused anytime to discuss the achievements and mistakes. Students can repeat each experiment as many times as needed, to practice their skills without causing any harm to animals.
