| and .pyr files already exist and just does rendering, getting its input |
| from these files. If RENDER_ONLY is not defined, then the program will |
| not use these files but start from the .den file itself. In this case, |
| there are two options: if PREPROCESS is defined, then the program will |
| not render, but will create the .norm, .opc and .pyr files from the .den |
| file for a future run of the program to render. If PREPROCESS is not |
| defined either, then the program will not produce these intermediate |
| files: It will start from the .den file, create the normal and opacity |
| tables etc as internal data structures, and render them directly. |
| |
| The SERIAL_PREPROC option tells whether the preprocessing phases (computing |
| the normal table or .norm file, etc.), should be done serially or in |
| parallel, when they are done. |
| |
| Clearly, if none of the three options are defined, the default is to |
| do parallel preprocessing and rendering without storing intermediate array |
| values. |
