Nothing much to see yet but I've decided to pick up grass rendering as the first project for my sample framework so I can later translate my ocean rendering to it and work on that (And hopefully fix that bug I had)
Mainly making this for some ranting and rubberducking KEKW
If you got nice resources feel free to send them here 😄

#

So first of all I want to mainly follow the Ghost of Tsushima grass rendering talk but use the mesh shader pipeline instead of traditional vertex processing

Procedural Grass in 'Ghost of Tsushima'

In this 2021 Advanced Graphics Summit talk, graphics programmer Eric Wohllaib will discuss how they generate acres of grass within reasonable memory and performance limits, techniques for rendering and animating individual blades, and methods for making thousands of individual blades of grass look like a natural field.

Why just touch grass when you can make it? jarikeks

mighty sundial Dec 10, 2023, 9:09 PM

#

Exactly

#

Making grass is much better than touching it

#

Anyways this is also mostly about jumpstarting my D3D12 sample framework

#

because honestly I need something to put into a portfolio if I want any chance at getting into this industry KEKW

more mesh shaders

#

I am pleased

mighty sundial Dec 10, 2023, 9:36 PM

#

hard ridge more mesh shaders

Ofc. because mesh shaders are awesome

#

and procedural geometry is a great usecase for those

hard ridge Dec 10, 2023, 9:36 PM

#

yessir

#

looking forward to the grass

mighty sundial Dec 10, 2023, 9:42 PM

#

grass won't be the only thing using mesh shaders (spoilers for future projects KEKW )

I sometimes truly hate cmake

I've also decided to make the progress public - should be starting with the first grass patch very soon as there isn't a lot of plumbing yet for my sample framework.

oh it's d3d12

#

:(

mighty sundial Dec 15, 2023, 12:22 PM

#

hard ridge \:(

why sad about it D:

#

fwiw most of the interesting stuff will be independent of D3D12 anyways

hard ridge Dec 15, 2023, 12:23 PM

#

because I'm a vulkan enjoyer KEKW

mighty sundial Dec 15, 2023, 12:23 PM

#

lmfao

#

fair enough, I do enjoy vulkan as well

#

but D3D12 is quicker to get running

hard ridge Dec 15, 2023, 12:24 PM

#

ye true

mighty sundial Dec 16, 2023, 11:47 PM

#

Got swapchain and command list plumbing done

#

now only resources are left and then I can finally get going with grass

your grass must beat avatar's

#

that's your objective son

mighty sundial Dec 17, 2023, 12:27 AM

#

for a second I was scared that this would be avatar grass

#

lmao

hard ridge Dec 17, 2023, 12:27 AM

#

push your limits

mighty sundial Dec 17, 2023, 12:28 AM

#

hard ridge push your limits

that I will do

mighty sundial Dec 24, 2023, 4:19 AM

#

I may have taken some days off for Alan Wake 2 + Cities Skylines 2 KEKW

#

But now it's time to actually think about the broader structure of that

#

I could cull grass tiles in task shader or I could cull individual blades and try some merging in mesh shader

#

quicker to get running
it has been a month and still no pics

#

listenyoupieceofshit

#

pics NOW or this thread is kill

vestal ice >quicker to get running >it has been a month and still no pics

I didn't work over the holidays

#

(and the first week of this year)

vestal ice Jan 9, 2024, 5:52 PM
