Render


Inside the “Render” tab, under the Settings section on the left of the Thea interface, there are included all the tools and the relative options for a proper photorealistic scene rendering.


Under the General sub-section, in the Main module is possible to choose the engine used for the final rendering. There are three different options: Unbiased (TR1), Unbiased (TR2) and Adaptive (BSD). The choice between the two unbiased rendering method depends explicitly on the scene to render: whilst the first is more inclined to handle efficiently outdoor situation and easier lighting conditions, the latter handles much better scene with adverse indirect lighting conditions. The BSD method is the only biased algorithm and its tuning is governed by the settings available in the Biased RT and Biased GT subsections. In addition, in “General” under the “Channel” module, Thea gives the user the ability to save some specific rendering channels (Normal, Depth, Alpha, ObjectID etc etc) in order to manage a more effective digital compositing process. Last but not least, it's quite important to note that Thea gives the user the options to choose among some rendering presets before firing the rendering process: these are optimized setups to better handle some common rendering situation and speed up the setup of the render engine. In the “Animation” tab some settings for the key-frame animation have also been placed and among the different options there's also one which enables the user to simulate the entire sun cycle defining the start-time and end-time of the cycle.


Tools


When the scene includes repetitive primitives ( a grass aggregate, a carpet, a long sequence of trees) whose handling might negatively impact the scene memory management, geometry instances are available in the Thea arsenal. All the tools and options needed to properly define geometry instances are located in the “T


ools” tab. The approach is


to select the model to get instanced (instance) as well as the geometry (canvas) where to proceed on with the instancing duplication. The instances can be “painted” on the canvas by using a mouse-driven approach or through a texture evaluation.


The specific Thea peculiarities can't be completely describe in such a short review. Concurrently at the software installation, a detailed PDF manual is copied on the application folder, in order to train the user to get more and more proficient with the Thea Studio as well as to get skilled on building
