4.5.2.3 Optimization Pane

This pane contains settings for the optimization during the rendering process. Here you can turn on/off various flags that try to optimize bounding and buffering to speed up rendering, often at the cost of increased RAM memory usage.

4.5.2.3.1 Auto-Bounding

This changes the bounding slab object threshold switch (+MBnn), or turns off auto-bounding altogether. Use the slider to set the threshold.

4.5.2.3.2 Ignore any "bounded_by" in scene

Early versions of POV-Ray had no automatic bounding to speed up rendering. Users had to manually creating bounding boxes to speed up rendering. For most scenes using the automatic bounding is faster and you should keep this setting on, but some old scenes may expect the old bounding mechanism.

4.5.2.3.3 Split Unions

Early versions of POV-Ray had no automatic bounding and handled unions a little bit different. Some scene files expect the old way unions could be used for and will not work with this option activated.

4.5.2.3.4 Use Light Buffer

Turn this on to speedup rendering. You only need to deactivate this option is when it does not work as expected.

4.5.2.3.5 Use Vista Buffer

Turn this on to speedup rendering. You only need to deactivate this option is when it does not work as expected.

4.5.2.3.6 Draw Vista Buffers

Turn this on to draw the vista buffers created. This is for your interest and for debugging only, it has no real use.
