W,A,S,D to move R,F to go up and down https://turbowarp.org/753555952/ for better perfs SIGMA IS A GREEK LETTER, NOT BRAINROT Instructions on how to use can be found inside of the project
Credits: @TheGoodGuy8000 for object rotation, strecthing and optimization @-Rex-Test- for his tri filler and his quicksorting @nampinanathali for lod idea @Bambozzle for his textured tri filler V1 (2022/10/30): shared, 15fps on my laptop. Based on my optimized version of @MathMathMath's tutorial so thanks to him V1.1 (2022/10/31): Now, obj can be rotated and stretched, thanks to @TheGoodGuy8000. Improved perfs, now 20 fps. V2 (2022/10/31): Now not only wireframe, thanks to @-Rex-Test- for his tri filler and his sort algorithm V2.1 (2022/10/31): Added shading! V2.2 (2022/10/31): Added backface culling, thanks to https://www.youtube.com/watch?v=wpNef1Nu4pA V2.3 (2022/11/02): Can now load obj form a string and not necessary a list. Support some materials. V2.4 (2022/11/03): Added shading for ALL models (no need to add normals in the model, it calculate them). Added 2 semi-wireframe mode (both look like cell-shading). Added colors and shading V3 (2022/11/03): Multi object support!!! V3.1 (2022/11/03): Opti (shortened var names, removed 6 useless blocks, removed useless vars, added a blank sprite) V3.1.1 (2022/11/04): Fixed some bugs V4 (2022/11/04): Z CLIPPING! V4.0.1(2022/11/04): Found some backface culling inaccuracies, added some basic colors to the materials V4.0.2(2022/11/04): Now support quads in the obj file (it will mostly not works with concave quads) V4.0.3(2022/11/04): Now support 5 sided polygons in the obj file (it will mostly not works with concave polygons) V4.1(2022/11/05): Added level of detail (lod)! If you go far away, the monkey head model will change to a less detailled one (you wont see it) and you will get better perfs! Thanks to for the idea V4.2(2022/11/05): Better backface culling V4.3(2022/11/05): Added skybox V4.4(2022/11/06): Added priority levels for the sorting V4.5(2022/11/06): Added a render distance V4.6(2022/11/10): Optimization :D V4.7(2022/11/10): 2.5D sprites V4.7.1(2022/11/11): Fixed skybox V4.8(2022/11/11): Optimized clipping and wireframe V4.8.1(2022/11/11): Optimized some more things (clipping and lod) V4.8.2(2022/11/13): Added 3D audio V4.8.3(2022/11/13): Now easier to use V4.8.4(2022/11/13): Minor optimizations V4.8.5(2022/11/13): Optimized "add to sort" block V4.9(2022/11/26): Added textures! You can now import textured models! Thanks to and for their textured tri fillers! To convert png textures to str, use this: https://xeltalliv.github.io/ScratchTools/Img2list/ V4.9.1(2022/11/26): Fixed a bug with textures in obj loader V4.10(2022/11/27): Sigma engine, added UV clipping, fixed bugs, optimized textures, added an option to disable backface culling for a material V5(2022/11/27): Added AABB collisions, try to enable collisions, the grey box has collisions! V5.1(2022/11/27): Added 3rd person view V5.2(2022/12/02): Made some optimizations V5.3(2022/12/02): Added LOD for textured materials V5.4(2022/12/09): Switched to new ultra fast tri filler, big thanks! V5.5(2022/12/10): Big optimization for textured models V5.6(2022/12/10): Added cell-shading (set wireframe slider to 2) V5.7(2022/12/19): Fixed flipped model importation v5.8 (2023/06/05): BIG optimisation when multiple models loaded v5.9 (2023/06/16): Bounding box V6.0 (2025/05/18): Optimisations and made the use of LOD easier V6.1 (2025/05/22): Optimisations, bug fixes, QOL features for people who wants to use this engine and added support for re-using models more than once V6.2 (2025/05/23): Added supports for point lights, multiple lights, colored lights, fixed bugs, QOL features, optimisations, better lightning formula Good 3D rasterization tutorials: -https://www.youtube.com/watch?v=ih20l3pJoeU (full 3D engine) - https://www.youtube.com/watch?v=wpNef1Nu4pA (backface culling) - 's one
