Apo Quality Render Settings

[JHughes]

Could someone explain the following items on the render screen and how they affect the quality of the rendered image? Are there suggested settings for these three? Thanks. (Please remember I am new at this so I do't speak Apo Geek completely. lol Thanx)

-Density
-Filter Radius
-Oversampling

In brief, density is proportional to the number of iterations. Larger values give better quality at a diminishing marginal rate. Filter radius is a measure of the size of the blur applied during anti-aliasing and works in conjunction with oversample, which, traditionally, is the linear multiplier for the image dimension for anti-aliasing purposes. It doesn't quite work like that in Apophysis, but for simplicity's sake, an oversample of 2 means the image is rendered at twice the linear dimension before being reduced - this process (anti-aliasing) reduces jagged edges and some noise.

I'd recommend doing a test render at density = 500, oversample = 2 or 3 and play with the filter radius settings in the Post process dialogue (check the box 'Post process after render') - you'll probably need to save and view the image externally for each change.

You can find out more than you need here: http://ideviant.deviantart.com/art/Rendering-Optimisation-1-73851834 Bear in mind that density was formerly called quality.

Thank you so much for the information, I have a better understanding of it now. I appreciate the help.

I would like to add my thanks for both the info and the link. Getting the best possible render seems to be quite a challenge at times.

Well worth it though.
