Examples with animated model? Maybe I missed it, didnt find. Will look again.

https://github.com/dotnet/Silk.NET/pull/1161 yep. this looks pretty good, and a straight port of the learnopengl one instead of my messy mesh system

no not for animated models

L

Lyris the Kitori•1/4/23, 1:14 AM

just for silk in general

Thanks, this one is enough to start, https://github.com/dotnet/Silk.NET/pull/1161

And for skeletal deformation we use vertex shader? (This part is total unknown for me, so want to be sure that I'm moving in right direction)

Redhacker2•1/4/23, 1:32 AM

Haha well I have one as well as well as my little wrapper thing as far as pulling mesh data out, no animations though

Bloppy•1/4/23, 6:39 PM

well I just wrote this code for loading an image as a texture, but the code responds with error cs8377. And I don't know the solution for this situation.

L

Lyris the Kitori•1/4/23, 6:40 PM

what is img.Data

B

Bloppy•1/4/23, 6:40 PM

I am using StbImageSharp

L

Lyris the Kitori•1/4/23, 6:40 PM

that error implies it's a 2d array

A

Aqua•1/4/23, 6:40 PM

you must use

fixed

fixed

fixed

fixed on the image data

B

Bloppy•1/4/23, 6:41 PM

so apparently img.data I was using as a parameter is a 2d array right?

A

Aqua•1/4/23, 6:41 PM

fixed (byte* ptr = img.Data)
  _gl.TexImage2D(..., ptr);

fixed (byte* ptr = img.Data)
  _gl.TexImage2D(..., ptr);

fixed (byte* ptr = img.Data)
  _gl.TexImage2D(..., ptr);

fixed (byte* ptr = img.Data)
  _gl.TexImage2D(..., ptr);

BBloppy so apparently img.data I was using as a parameter is a 2d array right?

L

Lyris the Kitori•1/4/23, 6:41 PM

maybe? idk i've never used it, look at it

A

Aqua•1/4/23, 6:41 PM

img.data is a byte array

L

Lyris the Kitori•1/4/23, 6:41 PM

oh

L

Lyris the Kitori•1/4/23, 6:42 PM

wait why is the inferred type parameter byte[] then

AAqua ```cs fixed (byte* ptr = img.Data) _gl.TexImage2D(..., ptr); ```

B

Bloppy•1/4/23, 6:42 PM

here's the result

LLyris the Kitori wait why is the inferred type parameter byte[] then

A

Aqua•1/4/23, 6:43 PM

wdym? its assuming T is

byte[]

byte[]

byte[]

byte[] cause thats what it is lol

BBloppy here's the result

A

Aqua•1/4/23, 6:43 PM

this looks like an issue elsewhere

A

Aqua•1/4/23, 6:43 PM

are you setting the texture before drawing?

AAqua wdym? its assuming T is `byte[]` cause thats what it is lol

L

Lyris the Kitori•1/4/23, 6:43 PM

well surely the function parameter of that overload is T[] not T, right?

A

Aqua•1/4/23, 6:44 PM

nah

A

Aqua•1/4/23, 6:44 PM

its T

B

Bloppy•1/4/23, 6:44 PM

I think not

A

Aqua•1/4/23, 6:44 PM

_texture.Bind()

_texture.Bind()

_texture.Bind()

_texture.Bind() should be it

AAqua its T

L

Lyris the Kitori•1/4/23, 6:44 PM

oh

B

Bloppy•1/4/23, 6:45 PM

you mean this method

B

Bloppy•1/4/23, 6:45 PM

oh now I see

A

Aqua•1/4/23, 6:45 PM

yeah, that will bind it
check in renderdoc to see if the texture has been created correctly, this looks like it could be a shader issue (also you should set

uTexture

uTexture

uTexture

uTexture in your shader before binding the texture, i would try that first)

B

Bloppy•1/4/23, 6:48 PM

Oh wait

A

Aqua•1/4/23, 6:48 PM

ah
that was going to be my next question
yep you need to bind it before setting the data

B

Bloppy•1/4/23, 6:48 PM

thx rollie

that helped me alot

After mentions here, I downloaded "Renderdoc" program, seems very useful. Never too late, learn something new

L

Lyris the Kitori•1/5/23, 4:51 AM

make sure to get the where-is-my-draw extension

L

Lyris the Kitori•1/5/23, 4:51 AM

its very useful

Problems

Aqua•1/6/23, 9:25 PM

any reason why SilkMarshal stringtoptr requires you to manually free the memory when

fixed (byte* ptr = Encoding.UTF8.GetBytes("text"))
  // things with ptr

fixed (byte* ptr = Encoding.UTF8.GetBytes("text"))
  // things with ptr

fixed (byte* ptr = Encoding.UTF8.GetBytes("text"))
  // things with ptr

fixed (byte* ptr = Encoding.UTF8.GetBytes("text"))
  // things with ptr

works fine?

A

Aqua•1/6/23, 9:27 PM

cause im starting to wonder if this is not the right way of doing things
except i have been doing this for a long time now and have had 0 issues with it

A

Aqua•1/6/23, 9:45 PM

hm. been looking and seems like

public class Thing
{
  void* whatever;

  public Thing(byte[] stuff)
  {
    fixed (void* ptr = stuff)
      whatever = ptr;
  }
}

public class Thing
{
  void* whatever;

  public Thing(byte[] stuff)
  {
    fixed (void* ptr = stuff)
      whatever = ptr;
  }
}

public class Thing
{
  void* whatever;

  public Thing(byte[] stuff)
  {
    fixed (void* ptr = stuff)
      whatever = ptr;
  }
}

public class Thing
{
  void* whatever;

  public Thing(byte[] stuff)
  {
    fixed (void* ptr = stuff)
      whatever = ptr;
  }
}

isn't valid
i've had no problems with that
but i guess i've been lucky?
so if that's not valid
wtf are you supposed to do instead
or have i just confused myself

GC handle? pass a pointer in?

A

Aqua•1/6/23, 9:49 PM

GC handle?

T

TechPizza•1/6/23, 9:49 PM

pin only when you need a pointer

AAqua GC handle?

TechPizza•1/6/23, 9:49 PM

GCHandle

TechPizza•1/6/23, 9:49 PM

long-term pinning managed memory is pretty bad though

A

Aqua•1/6/23, 9:50 PM

i don't need it much but its useful in certain situations
the struct needs to be

unmanaged

unmanaged

unmanaged

unmanaged and so i just store a pointer
