The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 		2 months ago

assets Bring in the gnu omni font for text, and rewrite my stats code to use c++ and then use that to calc FPS stats for an FPS display on the left. Debug build gets about 48, release gets about 500fps. Amit's code will probably do even better. 2 months ago

scripts Tweaking the build to turn on various debug options in GCC and enable -Wall -Werror on only our executable configs because turning them on globally causes most of the dependencies to fail. One thing to note is if you try to move the -D_GLIBCXX options from the project() to the executable() then you get segfaults inside the libc++ and other places. This is because the ABI changes when you enable these options, so you have to recompile _all_ dependencies with these options. 2 months ago
tests Brought in Amit's latest code and converted it to use either dumb lighting or his new torch lighting, then threw in the FPS counter from last night. 2 months ago

.gdbinit My gdb debug thing. 2 months ago
.gitignore First build that actually works. SDL_main errors before but didn't figure out the cause. 2 months ago
.vimrc_proj First build that actually works. SDL_main errors before but didn't figure out the cause. 2 months ago
Makefile The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2 months ago
README.md Add a README to start. Not much in it. 2 months ago
config.cpp Amit's code mostly converted to use the new texture.hpp but there's an error on line amt/pixel.hpp:472 2 months ago
config.hpp Finished the first pass of moving everything around and cleaning up as much as possible. 2 months ago
constants.hpp The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2 months ago
dbc.cpp Fixed that crash and cleaned up more variables for some study next. I might also try out my debug macros. 2 months ago
dbc.hpp First cut at a replica of the python raycaster. Left side almost works the same but have to sort out math differences. 2 months ago
dbg.h Fixed that crash and cleaned up more variables for some study next. I might also try out my debug macros. 2 months ago
main.cpp The tracy directory now has an experiment in getting Tracy to work. It's _not_ as easy as it is touted to be. 2 months ago
matrix.cpp First cut at a replica of the python raycaster. Left side almost works the same but have to sort out math differences. 2 months ago
matrix.hpp Fenscaster is now using the first version of Lode's DDA raycasting algorithm but the coordinates/angles in the left map view don't matchthe right view, and the right view distorts the distance to far wall so they're viewed at 'infinity'. 2 months ago

Simple Raycaster Study

This is a study project for me to learn the raycasting technique. It's an older technique that's not really used much but I'm learning game dev historically and it's definitely been used in the past (Doom).

I've been told to look into the following as well:
