BSPViewer

This is a simple program that displays Quake 3 BSP maps.

Almost everything here was based off the file format specifications found online here and here rather than the source code.

Building and Installing

Ensure that the following packages and their development files are installed properly:

• GNU GCC C++ and GNU Make on Linux
• MinGW or Visual Studio C++ on Windows
• CMake

Most of the libraries used should be downloaded automatically when building but SFML may require some additional packages on Linux first. You should be able to find more details here.

To build use the following commands:

mkdir build
cd build
cmake ..
make

Alternatively, you could use QtCreator to open up CMakeLists.txt to compile the code.

Usage

To use you will need an install of Quake 3 and the location of its data folder q3base. On Steam this can typically be found in C:\Program Files\Steam\steamapps\common\Quake 3 Arena\baseq3\.

A list of availible maps can be shown using: bspviewer /path/to/baseq3/

To load a map use: bspviewer /path/to/baseq3/ /maps/q3ctf1.bsp

• Mouse movement for looking
• WASD for directional movement
• Space to move up
• Shift to move down
• E to toggle collision
• Escape to quit
