27.8. Let’s adjust the project Bath_Piper.bin, which is included in the program. Below you can see the appearance of this project.
'Radiosity – Calculation of the reflected light' and high-quality anti-aliasing are the main factors that increase rendering time. Therefore, we will set ‘Anti-aliasing’ to 8 and switch off ‘Radiosity’.
The size of the image affects rendering time too, so the image size will be 640 x 480. The number of light sources as well as processing of transparent, shiny and reflective surfaces also increases rendering time. There is only one light source in the project – the lamp Bejorama1979 Guero.3ds. Below you can see light source settings:
We have used default material settings (Ambient and Diffuse) and set 0.03 ‘Reflection’ for all wall tiles, 0.10 – for all floor tiles.
We’ve adjusted objects using quick replacement and polishing buttons. All chromium surfaces – Chrome1, Polishing 2 and 3; the lamp - Gold_Dark_Gold material – Gold 1, Polishing 2; the vase with a leaf (55_Bowl.3ds) – vase material – Glass 5, Polishing 2, also we have changed the leaf material – we have made it more green. Ceramic surfaces – without changes, Polishing 3. The mirror (55_Mirror) - 04_Default material – quick replacement to mirror.
You can check other settings by yourself, their adjustment won’t cause any difficulties. Below you can see the result of rendering::
Rendering time in version 3.7 beta using Intel Core2 Duo 2.66 Ghz – 20 seconds.
Rendering time in version 3.62 using Intel Core2 Duo 2.66 Ghz (only one core was used) – 35 seconds.
