Human-computer interactive systems focused mostly on graphical rendering, implementation of haptic feedback sensation or delivery of auditory information. Human senses are not limited to those information and other physical characteristics, like thermal sensation, are under research and development. In Virtual Reality, not so many algorithms and implementation have been exploited to simulate thermal characteristics of the environment. This physical characteristic can be used to dramatically improve the overall realism. Our approach is to establish a preliminary way of modelling an irradiating thermal environment taking into account the physical characteristics of the heat source. We defined an algorithm where the irradiating heat surface is analysed for its physical characteristic, material and orientation with respect to a point of interest. To test the algorithm consistency some experiments were carried out and the results have been analysed. We implemented the algorithm in a basic virtual reality application using a simple and low cost thermo-feedback device to allow the user to perceive the temperature in the 3D space of the environment.
