[Java 2.5D] from scratch - Doom (1993) WAD map renderer / covering the floor & ceiling - Test 002

Oh, finally it&starting to look like a Doom renderer :) In this test, I was able to draw the upper and lower partial walls of the portals and also covered the floor and ceiling parts. But I¬ actually using portals yet, I&drawing all the polygons returned by bsp from the furthest to the closest. Let&see if i can extract the textures in my next tests. This project requires the original Doom Shareware version DOOM1.WAD file to test. References:
