I know they do editor time selection raycast with some hardcore jobs

tribal inlet Sep 13, 2022, 1:29 AM

#

yeah

#

do you need rigidbodies?

#

or just static collisions?

nocturne rune Sep 13, 2022, 1:29 AM

#

rigids

tribal inlet Sep 13, 2022, 1:30 AM

#

hmm

#

are you using vhacd?

nocturne rune Sep 13, 2022, 1:30 AM

#

i don't know what that is so maybe not

#

no i don't, you think that could somehow be fed by the compute shader at lower pcie transfer cost?

tribal inlet Sep 13, 2022, 1:32 AM

#

hmm

#

i guess i don't really know... i feel what you wanna do

#

the shape is not changing all the time right?

#

of your blobs

#

is it blobs or terrain?

#

if i were you

#

i would do jobs to do a super rough approximation

#

because you can store the voxels in a mip-like representation

#

on CPU

#

so it finishes in time for rendering

#

if you are on a modern platform

nocturne rune Sep 13, 2022, 1:39 AM

#

its terrain, it changes when things crawl on it, some can be displacement shader, but large carving has to be full on

tribal inlet Sep 13, 2022, 1:39 AM

#

you can probably dispatch the compute buffer early in the frame, and check on it later in the frame

#

okay so no rigidbodies that's good

nocturne rune Sep 13, 2022, 1:39 AM

#

yeah it's already stores as octree

#

not exactly mipmap though

#

but i see what you're saying

tribal inlet Sep 13, 2022, 1:40 AM

#

yeah remember i don't have any idea what i'm talking about lol

#

we're just brainstorming

nocturne rune Sep 13, 2022, 1:40 AM

#

no - rigidbodies are a must

tribal inlet Sep 13, 2022, 1:40 AM

#

i mean the character has a rigibody

nocturne rune Sep 13, 2022, 1:40 AM

#

or whatever can simulate the same effect

tribal inlet Sep 13, 2022, 1:40 AM

#

but the terrain does not

nocturne rune Sep 13, 2022, 1:40 AM

#

yeah

tribal inlet Sep 13, 2022, 1:40 AM

#

the terrain can be a concave* static collider

nocturne rune Sep 13, 2022, 1:41 AM

#

not really

#

it's got caves

#

but decomposition is someting i'm looking for anyway

#

however, not decomposition into meshes, decomposition into primitives

tribal inlet Sep 13, 2022, 1:44 AM

#

sorry i'm tired

#

you don't need to decompose it

#

you can cave it

#

it'll just work

nocturne rune Sep 13, 2022, 2:36 AM

#

i don't understand

tribal inlet Sep 13, 2022, 3:41 AM

#

i mean you don't have to use vhacd

#

for this application

#

sounds cool

#

it's gonna be sick
