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 and refines its quality through a few iterations, each iteration taking increasingly more time. The Live Render Coarseness option simply enables you to select the lowest quality (coarseness) the live renders starts with. More coarseness (larger pixels) provides faster frame rate during interactive manipulation at the expense of quality. The available options are 8, 6, 4, 2 pixels. The default is 8 pixels, favouring interactive responsiveness (particularly during camera manipulation). Users are encouraged to try less coarseness based on the interactive work they do and also based on 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:
| Option | Description |
|---|---|
| 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. |
