technically software rendering is done with hardware so it's also hardware rendering

raspberry pi pico emulator when?

P

PerkseyOP•4/9/23, 10:06 PM

basically my other side project is a shader-like assembly language that i was going to use on my FPGA to essentially dynamically configure & orchestrate computations done by more performant & specialized blocks on the FPGA

P

PerkseyOP•4/9/23, 10:06 PM

but i came to the conclusion i need to understand CPU design a bit better

P

PerkseyOP•4/9/23, 10:06 PM

so i'm implementing an M0 emulator

Aqua•4/9/23, 10:06 PM

isnt a cpu just a thing that goes beep boop and things happen

to quote rollie, it is a very fast hot rock that can do math

well you're connecting wires together instead of writing instructions

i am of the firm belief that sand cannot do math

F

Furball•4/9/23, 10:08 PM

Sand doing math is weird

A

Aqua•4/9/23, 10:08 PM

i mean technically cant you make logic gates out of literal sand

K

khitiara•4/9/23, 10:08 PM

sand cant do math. sand plus metal can do zappy things that humans can pretend is math

F

Furball•4/9/23, 10:08 PM

A big chunk of the world relies on sand being able to do math faster than humans

you can make them out of water for sure

Is there a call I can use to convert the pointer to the error message

DebugMessageCallback

DebugMessageCallback

DebugMessageCallback

DebugMessageCallback is giving me into an actual dotNet string? Tried

Encoding.UTF8.GetString((byte*) Unsafe.AsPointer(ref message), length);

Encoding.UTF8.GetString((byte*) Unsafe.AsPointer(ref message), length);

Encoding.UTF8.GetString((byte*) Unsafe.AsPointer(ref message), length);

Encoding.UTF8.GetString((byte*) Unsafe.AsPointer(ref message), length); but it is choking with encoding errors

~~Hmmm that seems to be returning a string representation of the pointer itself? I get 139814784783936~~

what?

I am dum dum. I was WriteLine'ing the pointer, not the resolved string

ah

Ended up with this little helper to enable debug output:

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

  public static unsafe void EnableDebugOutput(this GL gl) {
    gl.Enable(GLEnum.DebugOutput);
    gl.DebugMessageCallback((source, type, id, severity, length, message, param) => {
      var errorString = SilkMarshal.PtrToString(message);
      Console.WriteLine($"Message from OpenGL ({type}) with severity {severity}:");
      Console.WriteLine(errorString);
    }, null);
  }

I am a bit stuck on tutorial 3.2, I am getting very different lighting outputs. My code seems to somehow calculate lighting for all faces, while the tutorial code is lighting only the face that is directly in front of the light

M

Machinarius•4/10/23, 2:51 AM

Tutorial

M

Machinarius•4/10/23, 2:52 AM

Not sure why. I've checked that my shaders do the same, the vertexes and normals were straight-up copied

M

Machinarius•4/10/23, 2:53 AM

Any ideas would be greatly appreciated

M

Machinarius•4/10/23, 3:08 AM

This is the commit that introduced that lighting, in case anyone wants to give it a look https://github.com/Machinarius/Custom3dEngine/commit/203a1cf3a286d528c2052496dd658e7b9e01c54b

chairclr•4/10/23, 3:18 AM

this seems to be an issue with your vertex normals..? being incorrect? thats my guess

i am experiencing a problem running the wgpu examples at https://github.com/dotnet/Silk.NET/tree/main/src/Lab/Experiments

the

libwgpu_native.so

libwgpu_native.so

libwgpu_native.so file is copied to the

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so

runtimes/*/libwgpu_native.so folder, but the webgpu backend can only find it if i copy it manually to the root of the build folder

when building projects that reference other projects by files, libs arent copied around properly

L

Lyris the Kitori•4/10/23, 7:14 AM

its a dotnet thing

L

Lyris the Kitori•4/10/23, 7:14 AM

theres no fix

L

Lyris the Kitori•4/10/23, 7:14 AM

just copy it manually
