ZDBSP 1.17

[ReX]

GL nodes in a map that has both sets will never get used by the engine. (needs fixing...)

In other words, (until the fix) using both the GL & extended node build options doesn't do any good nor does it do any harm? If both are present in a GZDooM map which one takes predominance? Because, if that is the option to which the engine defaults, then we should not even bother using the other one.

Furthermore, in a GZDooM map, is it better to have GL nodes built or extended nodes?

[Graf Zahl]

Currently only the normal nodes are loaded. The plan is to load the normal nodes for gameplay and the GL nodes for rendering but the second part isn't implemented yet.

[Demolisher]

Are GL nodes faster for rendering? How big of a difference will it make?

[Graf Zahl]

No, they are a bit slower. On a large map like E1M6 of P:AR it's a difference of 0.5 ms on my system. The reason for this is that GL nodes contain more segs so for rendering more data needs to be processed. Without this speed hit I would have set it up a bit differently so that GL nodes get preferred more often.

So, why would you ever want to build GL nodes if they are slower?

[Graf Zahl]

Because:

- GZDoom needs them
- You need them for the textured automap

Normal nodes are useless when you want to draw the sectors as polygons.

[Demolisher]

That would make sense, I never knew the overall purpose of them.

Hello.

Please update the zdbsp-1.17-src.zip
It doesnt contain Makefile. I had to took it from previous release.

Regards,
Borg

The makefile is not missing. It was intentionally removed because it now uses CMake to create its build files.

Hello,
I tried to compile ZDBSP in Linux, but without success. What did I fail?

Does it work if you add the following line to the top of nodebuild.cpp?

#include <unistd.h>  

[ducon]

Yes, it worked.
Thank you.
