An image is rendered gradually in small groups of pixels called buckets. This option allows you to specify in what order the buckets are rendered. This option applies to both normal and live renders. The default scanning is ????????. The available options are:
|Horizontal||The buckets are rendered row by row, from left to right and from top to bottom.|
|Vertical||The buckets are rendered column by column, from top to bottom, and from left to right.|
|Zigzag||The buckets are rendered row by row, from left to right on even rows, and from right to left on odd rows.|
|Spiral||The buckets are rendered in a clockwise spiral starting at the centre of the image.|
|Circle||The buckets are rendered in concentric circles starting at the centre of the image.|
This options applies during normal renders only. It does not apply to Live Render (IPR), which is a separate rendering technique progressive in nature (and allowing interactive manipulation). For normal renders, when this toggle is turned on, the rendering rapidly starts with a noisy image and refines it progressively until completed. Progressive Render has a slight overhead and may increase render time in the order of 5-10%.
When using Progressive Render, the Filter Type and Filter Width attributes (specified in the Quality group of Render Settings) are ignored. A Box filter with a width of 1 is used instead. Also images rendering with this option may contain more noise / fireflies. Because of this, these images may differ slightly from your final renders using Maya Batch (remember that when using Maya Batch, progressive is ignored). Make sure to deactivate Progressive Render when rendering final frames.
The first section of this tab contains the Render View option for selecting the window (and application) in which image layers will be displayed on screen during rendering. See Image Layers (AOVs). It can be either the Maya Render View, 3Delight Display or Custom Frame Buffer. When this last option is selected, the render view used for rendering is specified through the
3deliht.config file. 3Delight Display is used by default.
The second section of this tab contains the names of the applications that will be launched to visualize the different data set/file specified in various 3Delight for Maya fields. The supported type of applications are listed in the table below.
|RIB||This application will be launched to view RIB files. The default application is WordPad on Windows and TextEdit on Mac OSX. There is no default application on Linux.|
This application will be launched to view rendering log files. The default application is WordPad on Windows and Console on Mac OSX. There is no default application on Linux.
|Image||This application will be launched to view images. The default application is 3Delight Display (a.k.a i-display) on all platforms.|
This application will be launched to view statistics output by the rendering process. The default application is Internet Explorer on Windows, Safari on Mac OSX and Firefox on Linux.
