Render View This option is for selecting the window or application that will be used to display the image layers while they are rendered during a normal or a live render. Live Render Coarseness In order to provide a quick feedback and allow interactive manipulations, 3Delight's live renders always start with a very coarse image that is refined through a few iterations, each one taking increasingly more time. The Live Render Coarseness option specifies the lowest quality (coarseness) the live renders starts with. More coarseness (larger pixels) provides faster frame rate during interactive manipulation at the expense of image quality. The available options are 8, 6, 4 and 2 pixels. The default is 4 pixels. Larger values (more coarseness) is usually preferred for moving objects and cameras because of the increased frame rate it provides. Smaller values (less coarseness) is usually better suited for editing light and shading parameters as it provide better starting image quality. Users are encouraged to set the coarseness to their preference based on the interactive work they do and the performance of their workstation. Scanning 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. It applies to both normal and live renders. The default scanning is Circle. The available options are:
Progressive Refinement This options applies to normal renders only. It does not apply to Live Render (IPR) – a separate rendering technique allowing interactive manipulations with a different progressive approach. For normal renders, when this toggle is turned on, the rendering rapidly starts with a noisy image and refines it progressively until completed. Progressive Refinement has a slight overhead and may increase render time to complete the image by about 5 - 10%.
