rational tools’ distribution makes the material creation as easy as possible. Unique, thanks to the revolutionary approach, this module offers a graphic representation of the sub-material sandwich composing the final desired material. This visual help results in an extremely intuitive creation process also thanks to Thea shaders explicative diagram who helps to understand the effect of the shader on the final material. If the material creation takes in account textures, Thea includes an advanced texture editor the “T


exture Lab”. In accordance to the overall system interface, this


module too has been designed to offer the most user-friendly approach. The currently-in-use texture can be easily manipulated to change the tonemap properties as well as texture transformations or even to handle multiple textures on different channels. A set of procedural textures completes the tool-set which is by far one of the most complete texture tool-set available for a “non-programmable shader” rendering application.

In order to choose among different environmental lighting conditions, the “Environment” module, gives the user the option to select between two categories or a combination of these ones. The first uses the “physical sky” model by which the scene is lit under the sun and sky conditions defined by a specific day and time and a defined place on the Earth. Using this lighting model, some parameters can be set in order to properly take in consideration the atmosphere turbidity or the ozone portion. The second lighting condition uses the Image Based Lighting technique (IBL). This technique, by using images, can replicate the lighting condition available when the image was shot. Basically the more the information available in the image the better the rendering result. Because of this behavior, high-dynamic range images (HDR or EXR) can be used in order to provide the best set of exposure information for the shot. These images can be also used as background images or in the reflection or refraction channel in order to enhance the final IBL lighting effect.
