CSG Compiler Last edited 1 year ago2023-12-18 11:31:16 UTC

This is the first of the main compiling programs that takes the info from the .map file produced by WorldCraft and prepares a .pt0 file for the BSP compiler to use. It checks WADs, and stores them, and checks for invalid brushes and invalid face planes.

More info from DOE, Snowdog:
CSG: This tool effectively slices/breaks up complex brushes into simpler polygons so the BSP tool can do its job effeciently and correctly. Think of it as a preprocessor for the BSP tool.

Stands for "Constructive Solid Geometery".

Input/process/output

Input:

• .map file

Processes:

• Combines brushes into solid geometries. For this it does the following:
  • Check for invalid brushes
  • Check for invalid face planes
• Read WAD textures

Outputs:

• BSP file [incomplete] containing:
  • Entities
    • Updates existing BSP file's data with -onlyents argument
  • Texture data, which can be either references to external WADs or embedded
    • Controlled with -wadinclude or -nowadtextures arguments, among others
• Intermediate files for BSP compiler (compiler tool-specific) containing geometry data
