14 Rendering

Rendering is the process of capturing a view of your 3D scene and displaying it as a 2D image. Once you've rendered the image, it can be used in other image editing or page-layout applications.

Rendering in Bryce uses multiple passes to generate the final rendered image. On the first pass, the image is rendered in large pixel blocks, and then, in successive passes is refined to produce finer detail. The final pass of the rendering is an anti-aliasing pass.

Using this method you can see how the final image will look. Things like colors and light/object placement are very easy to see even during the first pass or two.

Bryce renders images using multiple passes. On the first pass object placement and color are easily visible...

...on successive passes, the image becomes more refined.

Rendering an image requires a great deal of computation. Scenes with multiple terrains (at 512x512 each or more) can generate hundreds of thousands of height points. This can yield millions of polygons to hit with rays. Animations with many frames can require even more computation to render. The more complex the scene or animation, the more computational power is required for rendering, and the longer rendering can take.
