Rendering Control

This area of the GUI is used to control how the image is rendered.

Algorithm

This optionmenu allows the rendering algorithm to be selected from those supported by TSIPP. Refer to  TSIPP Rendering Options  for more details.
 

Oversampling

Enter an integer value in this field to control the degree of oversampling for anti-aliasing. Each pixel will be the average of the specified number of sub-pixels. The default value is one. Rendering time increases linearly as this value is increased. Oversampling is  ignored if the algorithm is LINE.
 

Automatic Mode

If this option is enabled, then the scene will be continuously re-rendered. This is useful for positioning items, as the effect of each movement in physical object or camera position is immediately seen. When this option is not used, then rendering occurs only when invoked manually with the Render button, and the rendering process can be observed, as the image grows from top to bottom on the screen. With the option enabled, the rendered image is not seen until the rendering process completes, and if any GUI interaction occurs prior to completion then that rendering is aborted and a fresh process initiated. Consequently, the option is of most use when rendering times are short, typically when the LINE algorithm is used.

If any error occurs then the Automatic Mode is turned off. This is to prevent an infinite loop developing in which any attempt to exit from the dialog entered on an error may trigger an additional rendering attempt and a further error.
 

Shadows

This option enables shadow generation. Shadows are generated only by spotlights, and then only providing that shadow generation is turned on for the individual spotlight and with this global option. Refer to the SippShadows  command.
 

Shadow Depth

Enter an integer to define the size of the depth map used to render the shadows. As a rule of thumb one could say that the depth maps
should be at least as large as the image itself (the default) but this may vary from case to case. Refer to the SippShadows  command.
 

Width and Height

The values entered here specify the size of the image when it is written to a PBM file or to the Perspective View. The Perspective View will be automatically resized when the Render button is hit.
