Nico de Poel	bbf87bbf58	Implemented backface culling per face, by adding plane and center point fields to the face struct and checking the plane's normal against the camera vector to the center point. This eliminates the need for per-polygon normal clipping and reduces the amount of redundant vertex copying, for a measurable speed boost.	3 years ago
Nico de Poel	ddffc8860e	Fixes to make things work on real hardware again: - Struct pointers need to be 32-bit aligned, otherwise the PS1 will crash - For this purpose, some structs have been padded to make them a multiple of 4 bytes in size - Vector data needs to be copied into scratch RAM at a 32-bit aligned address	3 years ago
Nico de Poel	3a7ea8d4b3	Debugging work: - Load map data using a macro, so I can easily change the implementation for all data chunks. - Implemented a visdata function that loads all 1's, so that every leaf will be drawn. - Point-to-plane distance now uses copies of input vectors. May or may not be faster. - Fixed fps counter rounding and disabled vsync so we can see the true framerate	3 years ago
Nico de Poel	a05a800da0	Implemented PVS decompression, leaf visibility check using PVS data, and front-to-back traversal of the BSP tree.	3 years ago
Nico de Poel	b7da18d0c8	First bits of code involving BSP traversal with front/back selection and math: determine the leaf that the camera is currently in.	3 years ago
Nico de Poel	5a3b6aac46	First implementation of world loading and rendering. No BSP logic or optimizations in here yet, but something is being displayed!	3 years ago
