anthraxAI game engine (Vulkan API): 3D model texturing, basic (first) lighting, depth buffer

hi guys I finished uh working on the first uh impression of uh 3D modeling like I guess the only thing that is still missing is shadows and uh I think that I will do it somewhere in the near future but like for now what I uh created it's already I guess uh mostly the uh AAA games and uh you can like do whatever you want just you can like move around but it's not a problem it's uh something that I will just improve in the future but uh now you can simply and really fast load your 3D model with the texture and it will be textured as you as you want it and also you can uh control and change lighting and some things as like specular or ambient strength and it's super nice and I will not talk in the my intro uh too much this time I will just show you how it looks and uh it still uh works amazingly in parallel with my 2D engine engine and uh yeah so uh now you can also see that here I included lighting deac window uh it's it it isn't hidden yet and I actually like when it's like mess and I can like uh be lost in functionality and uh yeah so I will just load my level where is I I I removed the background because it's uh not necessary now in my showing case and uh yeah I can I I can start with the uh the level that you all know with the animation and you see that I uh changed the back the background and also now I'm going to load my third level where I only process uh 3D meshes and here we go it's one sphere uh monkey and Cube I uh spent like 5 minutes on uh over UV tiling and uh texturing so I hope you enjoy it I really glad that my monkey looks like it looks I can still zoom and uh now you can uh can look at it in much better way because it's closer right uh let's take a look into my uh debug lighting functionality which I'm really proud of um here I in increase specular I can increase or decrease ambient and it will be super dramatic and also yeah my lighting is completely wrong right now you can uh sometimes see this like weird stuff that my sphere is lit from the two sides and it's super super stupid but I will I was I was super tired I will uh change it somewhere somewhere in the near future too oh but I also was able to fix my uh the um my B that I had with uh when I was sometimes resizing windows I had a lost device or timeout error uh now it's gone because like I just know everything about synchronization it's a joke and I also can uh change light color probably and it's also super funny I'm not sure yet how it's like it's it's just all this lighting uh stuff that I made I implemented uh super in a hurry so they might be super broken but um I will just change it some some like light position what's like it doing it's super weird but anyway I just like that it's uh controllable uh and changeable and maybe in some time I will fix it but it's still super cool that it looks like like it how it looks um so yeah I guess that's all for my presentation okay let's go briefly through the code uh I don't have like much to present uh today but um yeah you now here here you see the debug light function that is just like uh doing this lighting window that you saw in UI and I have here like my camera data buffer uniform buffer that I'm pushing to the GPU and I also increased it it's like now much much bigger I am also like yes all this datas are going to my draw function o um when I now in initialize I uh in initialize the scene I uh um I'm in yes here in init resources I am at the end uh um doing again this like reference to my resource data structure with the reference to the texture uh texture file uh that will we use uh to map our uh model like for example here it is and I used it also in blender and yeah so uh also here is my some kind of like position uh offset so I can like uh draw them uh not on each other I mean the models and uh H let me see if I change something else yes and like briefly you can take a look to my uh fragment Shader for lighting and uh yeah I just took the code from the learn open G uh website and reused their maths but I guess since it's not working or I'm doing something wrong I will I will I will look at this later oh I guess the thing that I can show off a bit uh is my new file image Helper and I where I took all the stuff that are related to image creation like image uh create info stuff uh image view create info stuff and I'm like have my separate function for creating a particular image uh also memory barriers uh copy function and now for example in uh when I create the texture oh also then I I created a DA buffer I forgot to say it's also really important um yes and like I have it like here this function uh that I just uh set up the dep format uh calling this image helper create image stuff I have also like my uh uh small structure which contains all this like texture and stuff information uh yeah and like the same thing I'm doing when I'm creating my textures I now also like calling image helper create image then I submit using memory barrier copy memory barrier and destroying freeing memory I think it's pretty nice and beautiful implementation I also wasn't able to help myself and not to open a render Dock and just like briefly take a look how it looks like when I have super super empty uh scene and stuff and uh I I won't I won't spend much time on it because I don't have much time yeah uh but I want just to show like when I'm beginning render pass and like we are starting to uh drawing my uh 3D objects just like super crazy and cool like I have this input and this like you see texture sampler and like uh now I have my like image that it was rendered here is also my depth buffer and like let's take a look how it looks I have just to increase a bit range like decrease and you'll see that each time I just add another object and it's super cool and I don't know if I I have to talk about it uh later uh in the future more uh but I guess I still will because I really enjoy using this program um yeah okay I guess it's all for today and I hope you enjoyed and next time I will try to improve my lighting and maybe add some camera movement and like so you can like see stuff around and uh I don't know what I will do next because I just I'm super super super super excited and I wish I and just ride my engine and no work no food no sleeping but like uh we all are humans so uh have a nice week and see you next time
