had a silly idea for block outlines using the bevel system. i take the dot product of the vector from the camera to the world position with the normal to determine if the bevel normal is pointing away from the camera, then add an outline based on that. there's some outlines where they don't belong but i can get easily rid of those
... i don't hate it? 🤔
lol the outlining has more than doubled the code in my fragment shader
texturing, lighting, and bevelling: 12 lines of code
just doing outlines: 19 lines of code
On the other hand I guess it would be fair to say these graphics are looking a little...... muddy
Eh? Eh? Eh? :D
i'm commander shepherd and this is my favorite spot on the citadel
(seriously i cannot get enough of looking at this particular subsection of a screenshot i took of the outlines in my voxel engine)
debating what i wanna do with grass in my engine. atm i have a block shader, and a model shader. i feel like i could efficiently implement shell textured grass by making a shell texturing shader, but i also don't want to balloon the number of different shaders i need to render all my terrain 🤔
i could just use the model shader, but it becomes a pain in the ass to implement shell textured terrain then
i could try and combine it with the block shader but they both do really different things
hmm if i want to add bits to the shell texturing so it doesn't look bad viewed side-on i kinda have to go the model route
though i figured out i can get away with only 6 variations to get all the edge transitions 🤔 that could be doable if a bit annoying
i'm overthinking the grass thing so i've made the textures required to make the shells for a 16-tile transition and i'll just generate the model for each of those 16 and implement them in the engine and move on so i don't wind up blocked by choice paralysis
if i want i can always just change it later
here it is compared to my style guide image. how did i do, chat?
i probably wanna pull the grass away from the edge a bit more because it obscures the outlines, but i'm pretty happy with this overall
here's another close up i really enjoyed of the terrain in my block game
i've got columns of chunks working, but they're not really connected at the moment so i gotta fix that next
chunks connect properly now! with bonus shot of the sprawling cave systems beneath the surface
i made a staged chunk generation system where chunks can request their neighbors be generated but only up to a certain stage, which keeps the generation from going infinitely in all directions, because the requested stage must always be lower than the chunk's current stage of generation
@eniko Another headache appears when you allow voxels to be mutated (i.e: breaking/adding blocks). Now a mutation can invalidate meshing work that's currently in-flight, leading to a 'missed' block change that's not reflect in the mesh. We solved this by incrementing a per-chunk counter every time a mutation occurs. If the result of the generator's work doesn't match the most recent counter, we spawn another generator to ensure we dont miss the change.
It's a proper distributed systems problem!
@jsbarretto it's interesting how aligned we are in our approaches because i was thinking of doing that XD
honestly makes me feel like doing all this by my lonesome a bit of a fool's errand but... :')
