Rendering of Projected Lights

[greebo]

As it seems, the rendering of projected lights is not working anymore in DarkRadiant since I changed some stuff during my work on the draggable projected lights. It's still working in GtkRadiant, so it's definitely because of my changes.

 

I did some comparisons between the relevant code sections and tried to simluate the behaviour of the state before I made the changes, and I think I got this right, but the lights are still not rendering correctly.

 

From what I can see the projection matrix code is still unchanged, so this part should still work. I tried to setup a build environment for GtkRadiant using VC++ 2005 but I failed after some time, as it complains about some type conversion error in the type-cast system (can't remember the actual message, but I think it was something about casting const to non-const).

 

@namespace: Are there some special compiler flags necessary to build GtkRadiant? It would be really helpful to add some debug output in the GtkRadiant code to check against the DarkRadiant render code. It's probably something with the light bounds but I can't solve it from just reading the code alone.

Gtk comes with already setup VC2k5 projectfiles, what are the problems?

[greebo]

Yeah, I imported those files and added the GTK-headers to the project settings. It stopped compiling somewhere in the main codebase. I'll have to look at the error output on my other machine, but it was related to the TypeCast stuff. It complained about const-ness or something like that. I'll post back here as soon as I wrote down the exact error message.

Strange, we used VC2k5 in the past development phase and for the release build.

Did you download the gtkr-dependency package?

[greebo]

Not that I remember, I just downloaded it from the SVN repository. What's that package exactly? I guess it can be downloaded from qeradiant.com?

 

edit: Ok, found the link in the COMPILING file, I will check that out and post back here.

Still no luck with getting this to compile without errors. I got a few thousands of warnings ("C++ exception handler used, but unwind semantics are not enabled.") which I could get rid of, but there are still a few errors when compiling the libs and the GtkRadiant project. This is an example of the error log at plugin.cpp:

I also had to set the include paths of all the gtk, mhash and whatnot header files in the project settings after downloading the gtkradiant dependency package (I removed the other paths that I had added before that, so I think that's clean).
