/* |

|
* These routines are designed to aid the programmer who wishes |
| 23 |
|
* sort of context, so it is impossible to simultaneously run |
| 24 |
|
* this library on multiple scenes or in multiple threads. |
| 25 |
|
* You get one scene and one thread, and if you want more, you |
| 26 |
< |
* will have to go with the process model used by the programs |
| 27 |
< |
* gen/mkillum, hd/rholo, and px/pinterp. Finally, unrecoverable |
| 28 |
< |
* errors result in a call to the application-defined function |
| 84 |
< |
* quit(). The usual thing to do is to call exit(). |
| 26 |
> |
* will have to go with the process model defined in raypcalls.c. |
| 27 |
> |
* Finally, unrecoverable errors result in a call to the application- |
| 28 |
> |
* defined function quit(). The usual thing to do is to call exit(). |
| 29 |
|
* You might want to do something else instead, like |
| 30 |
|
* call setjmp()/longjmp() to bring you back to the calling |
| 31 |
|
* function for recovery. You may also wish to define your own |
| 77 |
|
* restarted at any point by calling ray_init() on a new |
| 78 |
|
* octree. |
| 79 |
|
* |
| 80 |
< |
* The call ray_save(rp) allocates and returns a buffer |
| 80 |
> |
* The call ray_save(rp) fills a parameter structure |
| 81 |
|
* with the current global parameter settings, which may be |
| 82 |
|
* restored at any time with a call to ray_restore(rp). |
| 83 |
|
* This buffer contains no linked information, and thus |
| 89 |
|
* same as the defaults for rtrace.) |
