Game Development

naw, it doesn't

steam has its own thing

Unity does not support any steam api functionality

In a way, I kinda am glad they don't

I have more granular control over the implementation

I would hope that Steam has some kind of a link up, but...

There is a Steamworks.NET api you can use

6:45 PM

Lowpoly done...

Very good

yay

got in

finally

Someone is spoofing Sie

that's a shadow

6:46 PM

ban him

shutup Jon lol

doesn't look like a shadow

looks like an illuminati triangle

@jgallant Of course it does...

wtf is that on the left?

6:49 PM

Yes, that is totally how I want the UVs unwrapped, Modo. thanks.

Sie

it's your soul

this conspiracy goes deeper now

Should make an Egyptian name for her ... Tallowtamun ?

First thing that came up was to porte-manteau Nefertiti ... nope, not doing that.

art...

Today I were talking to my prof about the game then the sketches I drew came up. I started to explain stuff then I realized, I enjoyed this.

I enjoy graphic programming too... but I don't think I enjoy networking programming that much... I find networking interesting..

So I ordered tablet that's 90 bucks total

I am going to be part graphic programmer and also an artist! YES!

Can you program?

If you can program, and enjoy it, and enjoy doing the artwork, that's a pretty powerful niche.

I am kinda making my own graphic engine. Yes. Program me can do a bit. I am a powerful niche weirdo!! YES

#feelsgoodman

In what?

I mean APi

@Bálint me?

7:18 PM

You

@Stephane most (big) Egyptian names meant something

Tutanhammon: Follower Hammon, he later changed it to Tutankhamon, follower of Khamon

Or the other way around, I can't really remember

Yeah but I'm not taking an ancient Egyptian dead language lesson, just making up an egyptian sounding name :P

@Stephane reshafim.org.il/ad/egypt/glossary.htm

@Bálint I server the DirectX C++!!

(current task in progress, shadow map is so weird on the left)

That seems like a floating point issue

could it be that I am dividing by zero?!

7:29 PM

@BlueBug that's called shadow map acne.

oh... my bias is too small?

Q: Shadow map perspective aliasing

2

It seems impossible to remove this sort of perspective aliasing when the surface is nearly parallel to the light direction. I have tested several different shadow acne removing techniques: Constant bias doesn't work: Introduces peter panning on biases large enough to remove the issue Slope-s...

yes, common problem.

Instead of checking whether the depth at that pixel is less than the depth in the sun's perspective depth map, try checking if the current depth plus some small amount is less than the depth at the sun's depth map

That makes it disappear

What happens basically, is that floating points aren't very accurate, and the faces think they are obstructed by themself

@Blue Do you have diffuse shading BTW? The 2 supposed to be combined to result in a nicer effect

First scene is forward, then the second is deferred scene. I have two modes of rendering running at the same time in the application

Deferred doesn't have to deal with shadow acne

7:40 PM

I am trying to wrap my head around "faces are thinking they are obstructed by themselves"

I am trying to understand why deferred doesn't deal with this issue while forward needs to deal with it

Because you recalculate the depth from the depth buffer, thus you make it innaccurate

Depth maps have a higher float density closer to the camera to make z-fighting less visible

Your sun is a certain distance away from the camera, so it becomes pretty inaccurate

E.g. The sun's depth buffer think a certain fragment is at 10.653, but the fragment is at 10.652 on the z coordinate, thus it thinks it's behind something (I exaggerated a bit)

They both have to deal with that issue.

Storing the distance in a dept buffer and recalculating it should introduce some inaccuracy, doesn't it?

it works the same way in forward and deferred: The light has to calculate it's own depth map.

Strange, I remember something wrong

Then I have zero idea why it's not present on tbe right pic

7:49 PM

oh I fixed it already... the deferred rendering is kinda complete

the forward rendering came second after I finished deferred rendering

now I understand what you mean by "faces think they are obstructed by themselves"

I see... because all the values in depth map is so "dense" like all the values get kinda clamped, it becomes in accurate I see...

@Blue Do you have an account on Computer Graphics

?

what do you mean? account on computer graphics? Do I major in computer graphics?

There' a computer graphics SE, specialized for these kind of things

wooha!!!!!

Stuff like simplex noise and shaders go there

7:53 PM

WOOOHA!

MIND BLOWN

*MIND = BLOWN

It's a nice SE

YESSSSSSSSSSS dances in the joy I needed this SE

Glad I could bring it to your attentiom

7:55 PM

The Cornell Box

General discussion for computergraphics.stackexchange.com

hello darkness my old friend. Nobody is here, so cold.

@BlueBug Yeah. gamedev.SE "tolerates" graphic questions that are frequent to game dev or specific to game engines but generic rendering questions should go to computergraphics.SE

Especially if it's your own engine.

This looks look.

Must be new I guess? Since it is "beta"

eh, I think it's all beta :P

It just got out of closed beta

Like Steam on Linux is still in Beta

7:58 PM

@Stephane stuff like Navier-Stokes equations and basically any graphical algorithms go there

It's an interactive version of GPU gems

@Blue also, check out gpu gems if you don't already know about it.

developer.nvidia.com/gpugems/GPUGems/gpugems_pref01.html

this book?

@BlueBug essentially, if it's "how can I do <computer graphics technique X> in Unity3D" or "in Unreal" it can go in gamedev.SE
If it's directly in OpenGL, DirectX, or software rendering, it should go in computergraphics.SE

I feel like previously graphic related questions just didn't have anywhere to go besides gamedev.SE

so it kinda float in gamedev.SE... I think... because it is kinda related to game dev I guess?

That book

Or books, there are 3 of them

Yeah, personally I don't flag those OpenGL/DirectX questions and I still answer them in gamedev.SE if the person is working on a game

8:03 PM

It's very easy to find graphics related algorithms since we had a lot of excess GPU power and VRAM

This looks like such rich resources to learn from

ARG! I hate UV unwrapping hands.

and it is so organized and FREEE!!!

@Stephane you could paint directly onto the 3d model

8:06 PM

I'm UV unwrapping for baking

Oh

There's already a colored highres version

What I should do from now on is model and UV unwrap them in T-poses then bend them and fix them into A-poses before skinning.

Or not give a damn and just work in T-poses because the character is going to be just ~100 pixels on screen...

ok I want to ask this question "in forward rendering what's the go to technique to smooth out rigid shadow due to low resolution shadowmap texture?"

can it stay as gamedev? or probably graphics?

graphics would be the place.

I think the UV unwrap tool is trying to tell me something...

Fitting massage for such a task.

UV unwrap is a pain.

8:19 PM

@Stephane That detail is a lot for a 100*100 pixel area

Yeah. There might be some cinematic close-ups tho if I can be bothered...

Well, not of that particular character (it's just a placeholder) but I'm using that as practice.

BTW, I'm always on phone, and your profile picture in this size looks like an ape

Just thought I share that with you

A green ape?

No

The negative space (grey stuff in the background) is the fur, the green stuff is the eyebrows, and the orange is the fave

(It's very hard to find a PG-13 picture of pavians, they have quite a big...manhood)

oooh I see. yeah

8:44 PM

@BlueBug I don't think there's a one size fits all solution, but there are lots of solutions. Using a linearly blendable shadow format like variance, exponential, or convolution allows you to use texture filtering hardware to do basic filtering, and also enables you to pre-filter with regular blur kernels on the shadow map itself

If you don't want to use a fancy format for depth storage, then you can do things like PCF which is basically just shadow testing a few nearby points and blending the binary shadow samples to get a smoother test

Okay, now I gotta remember how to bake textures... the steps are so finicky.

If you want to get extra baller with it, you can do PCSS which basically is using the shadow map first to judge how far away the shadow receiver is from the shadow caster by sampling nearby points, and then using that distance to control blur amount. It produces way more realistic shadows that start hard on contact and then become blurry as the distance increases, like real shadows

I like that approach the most, and to implement variable sized blur efficiently, I like to use a linearly blendable format (I prefer ESM) and take the integral of your image data, which then allows you to evaluate any size box average filter using only 4 texture samples

Halfway... Cripes

baked and exported... Now to see if it renders :P

hahaha it's trying to animate it without skinning

Uploading video capture ...

Maybe I'll edit her some more and make her into a bad guy. Make an Egyptian-ish temple level...

LMAO I've been listening to so much nightcore that all my YT suggestions shows up with NSFW anime chicks :D

I need to add the skinning...

9:37 PM

WHY IS SHE HUMPING THE PLATFORM

lol

LOL gimme a few minutes to create a weight map...

The animation's probably gonna look really weird with a dress...

@MickLH I like that. It sounds fancy. Do you think it will work in 100+ light scenarios though?

Holy #$ it looks fine

oh wait, nope. fingers are a bit messed up.. close enough

Let's see if YT accepts that 1080p60 video capture...

It'd look better if I added specular maps but that'd be a lot of extra work having to bake a 3rd texture map for everything, and then it's also a 3rd texture the GPU has to deal with unless I merge it into the normal map.

#OptimizedForTVScreens

10:33 PM

@BlueBug It can be cheap but it's not free. PCF doesn't require any pre-processing but does require more shadow samples, while pre-filtering requires evaluating a blur kernel on the shadowmaps every time, but then costs nothing extra to sample

Mmmmmhmmm

@Bálint This is exactly what the "bias" he referred to is. He's already doing that.

And it's not really a very good solution because it makes all the shadows creep over a small distance and only moves the problem to heavier angles

In order to handle grazing angles well that way, you have to have an unacceptable amount of shift in the overall shadow position, so objects on the ground look weird from their shadow being offset

You can help the situation a bit by measuring the surface normal and using that to compute a tighter bias for each sample

@StephaneHockenhull still humping.

But now it's humping as it's supposed to.

HD humping

ahem! 60fps 1080p 16x MSAA humping.

it probably wont hold at 60fps +16x MSAA once I add the environment on my GTX 560M tho :P

Q: How do I make a launcher for multiple executables?

11:09 PM

web.archive.org/web/19990117034445/http://…

Someone just posted this in the Python chat

How did I not see this before, this is amazing

I'm trying to make a launcher for a game I like that compiles the vanilla version and the mods into one launcher. I want to make it so I can choose between the versions, maybe with a rudimentary GUI. The original versions of the game are in Java, but I'm converting them to .EXE with Launch4j, and...

java launcher

I'm not sure on this

I'm pretty sure this guy's talking about Minecraft, but that already has a launcher that does everything he wants

I'm calling it now: that question will degenerate into basically "I have no knowledge of programming. Please write it for me."

John Hamilton

seems like it

most likely a custom server launcher

Not sure why he wants to convert java to EXE

It doesn't have any benefits, it's slower, it's not runnable on a lot of platforms, etx.

If I wanted to be nitpicky, I'd say he can't convert java to EXE, only the jars.

@Stephane I think I hit an unclear close on it.
