TurboCAD Pro includes a robust material editor, and numerous shaders to create materials and their finishes with a real-time preview that is available even on a selection from the model instead of just a simple cube or sphere (also available). When creating or altering materials there are extensive descriptions of each shader in the dialog window to simplify each step.
Bitmap textures may be brought into TurboCAD and used as material textures. Included is support for transparency patterns. This can be useful for entourage, or landscaping and a 2D image of a tree can render much faster than a high-polygon 3D modeled tree with each leaf being calculated separately.
There is also robust support for lighting and luminances. Lights are OpenGL based, are quick to add and use, but are more limited in their options than Luminances (see below). Lights may be added with a click, and their properties adjusted in the Design Director, which also enables creating light sets that can be turned on or off as a group. Light types include:
Each light has many different properties that can be managed, including the color; intensity; fall-off; shadow softness; and more. Some that are directional specific may include properties such as the beam sharpness, penubra and umbra (the angle of the cone of light and the darkness in the center of the beam, useful for flashlights).
Luminances include advanced lighting properties that can be assigned to the whole model, or to specific objects within the model. Any number of lights may be combined, so that an Ambient luminance may be used, then augmented by other lights and luminances.
With each light and luminance there are numerous properties. Combine them effectively and the possiblities are endless. Create natural lighting for various conditions, artificial lighting to simulate any environment necessary, or mood lighting to emphasize elements of a design and provide an impact. Lighting is a very powerful element in the design communication process.
