it implements a bunch of useful things for futures

#

i think its not used much in the library though anymore, maybe only for the examples

potent quest Jun 24, 2023, 10:57 PM

#

I guess tbh i should expect a lot of crates but man i don't like having a lot of external crates

#

idfk why it makes my project feel bloated

shadow trench Jun 24, 2023, 10:57 PM

#

the thing in rust is you dont want to reinvent what crates already do

potent quest Jun 24, 2023, 10:58 PM

#

ya true

shadow trench Jun 24, 2023, 10:58 PM

#

also they dont get recompiled until you update them

potent quest Jun 24, 2023, 10:58 PM

#

but there's just extra baggage that i just don't need

#

but you're right don't redo the wheel

#

which is why im a professional wheel maker 😎

shadow trench Jun 24, 2023, 10:59 PM

#

tbh phobos doesnt depend on a whole lot

#

i can get rid of layout-rs I think

#

let me do that actually

#

rayon is only for integrating with rayon if youre also using rayon

#

ash, ash-window - obviously required
raw-window-handle - interop with other windowing libraries
gpu-allocator - like VMA
derivative - derive Debug while ignoring fields, this is a proc macro so not included in the final result
futures - almost everything will depend on this eventually
petgraph - graph used in the internal representation of the render graph
winit - integration with winit is provided, but can be disabled
anyhow, thiserror - any project will have these
spv-cross - shader reflection
log - logging, most projects will have this one way or another
rayon - optional rayon integration if you are using rayon
static_assertions - tiny macro lib, though I dont think im using this anymore
fsr2-sys - FSR2, optional
widestring - wide strings for fs2, only enabled with fsr2 on
multimap - used in the pool, its just a HashMap<K, Vec<V>> but with some utilities

#

i dont see much room for removing dependencies here

potent quest Jun 24, 2023, 11:07 PM

#

i see

shadow trench Jun 24, 2023, 11:07 PM

#

i do also want to minimize them though, its not like i just throw new ones in for no reason

#

ooh ok

#

thiserror?

shadow trench Jun 24, 2023, 11:08 PM

#

That’s used for generating error trait impls

#

Its also a proc macro

is there code in phobos showing how the examples are ran?

now i need to figure out what i did bleakekw

#

antyways on my c++ project i am getting linker errors
this is supposed to be the part where i give up i think

#

wtf im supposed to move all my function definitions from my .hpp to my .cpp for template classes?

mild flower Jun 25, 2023, 4:23 AM

#

no

potent quest Jun 25, 2023, 4:25 AM

wrong way i meant

#

i meant .cpp to .hpp

#

@mild flower

mild flower Jun 25, 2023, 4:25 AM

#

yes

potent quest Jun 25, 2023, 4:25 AM

#

okok thank you

#

why?

#

eh ill say its compiler wizardry

mild flower Jun 25, 2023, 4:26 AM

#

no

#

the reason is that you cannot instantiate a template without seeing its definition

#

you get a linker error because the code for that instantiation hasn't been generated

potent quest Jun 25, 2023, 4:27 AM

#

ohh that makes sense

mild flower Jun 25, 2023, 4:28 AM

#

you can manually create instantiations of the template, which allows you to define the template function in a file, but it kinda goes against the point of templates in the first place (being generic)

#

because you have to place the manual instantiations somewhere that can see the full definition of the template (probably in the cpp file where it's defined)

potent quest Jun 25, 2023, 6:02 AM

#

oooh ok

that's as fast as you're gonna get

GLTF has been working pretty fine for me

i am once again suggesting that relying on normals in a program where you edit terrain with brushes feels odd to me
#wip message

young oar Jun 28, 2023, 1:32 AM

#

How so?

coarse yoke Jun 28, 2023, 1:35 AM

#

custom-normals are primarily useful when you have a higher resolution mesh that you are trying to decimate

#

without the higher resolution source, you can't really modify that unless you reconstruct it

young oar Jun 28, 2023, 1:36 AM

#

Right yea

#

I thought you were talking about like... normal normals that are stored per vertex

#

Cause I don't think you can do lighting without those lol

coarse yoke Jun 28, 2023, 1:37 AM

#

yeah just automatically generated ones that smooth out the surface aren't goin away

young oar Jun 28, 2023, 1:37 AM

#

Yep

coarse yoke Jun 28, 2023, 1:41 AM

#

i actually don't even understand the supposed benefit of custom normals anyways, shouldn't it require more data than just storing the heightmap would? i guess if your heightmap is like 32 bit and your normal channels are 8?

#

idr who was using them though 🙂

young oar Jun 28, 2023, 1:46 AM

#

Right yea

#

Iirc voxel plugin (for ue4) uses axis aligned normal maps only for chunks that are lower LOD

coarse yoke Jun 28, 2023, 1:56 AM

using it for LODs makes sense

i think jake is just figuring out the autogenned ones there so it's not a relevant example

We introduce a novel transmittance model to improve the volumetric representation of 3D scenes. The model can represent opaque surfaces in the volumetric light transport framework. Volumetric representations are useful for complex scenes, and become increasingly popular for level of detail and sc ...
