Is there any tutorials of programming on dx11+ on silk.net?

I have a question about quaternions

var rotator = Quaternion<float>.CreateFromAxisAngle(Vector3D<float>.UnitY, MathUtils.Radians(0.01f * 360.0f));
var position = new Vector3D<float>(100.0f, 0.0f, 0.0f);
var nextPosition = Vector3D.Transform<float>(position, rotator);

var rotator = Quaternion<float>.CreateFromAxisAngle(Vector3D<float>.UnitY, MathUtils.Radians(0.01f * 360.0f));
var position = new Vector3D<float>(100.0f, 0.0f, 0.0f);
var nextPosition = Vector3D.Transform<float>(position, rotator);

when I do that, nextPosition equals (99.80267, 0, -6.2790513)

I was expecting that the radius would stay 100???

If you calculate the magnitude/length of the returned vector, it does equal 100
the radius is still 100, the positions have just been transformed by the very minor rotation you're doing

ahaha you're right

MMercuryBulsara Is there any tutorials of programming on dx11+ on silk.net?

none that i'm aware of, but it should be about the same as C

Darn

Lyris the Kitori•11/5/22, 4:09 PM

any C tutorial will apply nearly 1:1

How does one create the debug messenger?
vk.GetInstanceProcAddr
vk.GetInstanceProcAddr
vk.GetInstanceProcAddr
vk.GetInstanceProcAddr only returns
PfnVoidFunction
PfnVoidFunction
PfnVoidFunction
PfnVoidFunction which doesn't contain what i need... is there a built-in way with silk or am I missing something? Found it out, didn't realize it was an extensions nuget

Hey Everyone,

I am trying to pass my scene data into my compute shader to raytrace.
And I am trying to get the RayHit[] once I am done
I have the following SSBO code (at the bottom) in my .frag shader .

struct Triangle
{
    int id;
    vec3 v1;
    vec3 v2;
    vec3 v3;
    vec3 nor;
};

struct RayHit
{
    int triangleID;
    float distanceHitAt;
    vec3 inRayPos, inRayDir;
    vec3 outRayPos, outRayDir;
    vec3 surfacePos, surfaceNormal;
};

layout(std430, binding = 0) buffer SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}RTSceneData;

struct Triangle
{
    int id;
    vec3 v1;
    vec3 v2;
    vec3 v3;
    vec3 nor;
};

struct RayHit
{
    int triangleID;
    float distanceHitAt;
    vec3 inRayPos, inRayDir;
    vec3 outRayPos, outRayDir;
    vec3 surfacePos, surfaceNormal;
};

layout(std430, binding = 0) buffer SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}RTSceneData;

struct Triangle
{
    int id;
    vec3 v1;
    vec3 v2;
    vec3 v3;
    vec3 nor;
};

struct RayHit
{
    int triangleID;
    float distanceHitAt;
    vec3 inRayPos, inRayDir;
    vec3 outRayPos, outRayDir;
    vec3 surfacePos, surfaceNormal;
};

layout(std430, binding = 0) buffer SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}RTSceneData;

struct Triangle
{
    int id;
    vec3 v1;
    vec3 v2;
    vec3 v3;
    vec3 nor;
};

struct RayHit
{
    int triangleID;
    float distanceHitAt;
    vec3 inRayPos, inRayDir;
    vec3 outRayPos, outRayDir;
    vec3 surfacePos, surfaceNormal;
};

layout(std430, binding = 0) buffer SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}RTSceneData;

When I call Gl.BufferData<>()
Do I assign it a struct like the following:

C#
struct SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}
.
.
SSBO[] sceneData;
.
.
.
Gl.BufferData<SSBO>(BufferTargetARB.ShaderStorageBuffer, sceneData, BufferUsageARB.DynamicDraw);

C#
struct SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}
.
.
SSBO[] sceneData;
.
.
.
Gl.BufferData<SSBO>(BufferTargetARB.ShaderStorageBuffer, sceneData, BufferUsageARB.DynamicDraw);

C#
struct SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}
.
.
SSBO[] sceneData;
.
.
.
Gl.BufferData<SSBO>(BufferTargetARB.ShaderStorageBuffer, sceneData, BufferUsageARB.DynamicDraw);

C#
struct SSBO {
    RayHit HitData1[RAY_BOUNCE_MAX];
    Triangle modelTriangles[];
}
.
.
SSBO[] sceneData;
.
.
.
Gl.BufferData<SSBO>(BufferTargetARB.ShaderStorageBuffer, sceneData, BufferUsageARB.DynamicDraw);

I have omitted code in between but is the assignment carried out this way?
I keep coming across alignment as a concern but am not sure where to start about that or if I even need to worry when using Silk

L

Lyris the Kitori•11/6/22, 3:36 AM

alignment will need to be worried about in Silk, generally the rule of thumb is, if you have to do it in C, you probably have to do it in Silk too (aside from buffer swapping)

Lyris the Kitori•11/6/22, 3:36 AM

ive never used std430, so i cant help here, maybe the GP discord can help more

L

Lyris the Kitori•11/6/22, 3:36 AM

its in this channels pinned messages

I

Invar•11/6/22, 3:39 AM

I am using 430 because a lot of examples are. More than happy to change it if I can get this solved.

I

Invar•11/6/22, 3:39 AM

Thanks!

I

Invar•11/6/22, 3:39 AM

Will check out the GP Discord as well.

Hey

K

Khalid•11/6/22, 5:27 PM

Im trying to build a maui .net application but i want to insert a 3D model to it and hopefully have emissions on it

K

Khalid•11/6/22, 5:27 PM

does silk work with maui

L

Lyris the Kitori•11/6/22, 5:27 PM

we do not support MAUI at the current time

K

Khalid•11/6/22, 5:27 PM

meaning does it work also on android and ios mac and windows

K

Khalid•11/6/22, 5:28 PM

whT SHOULD i do

L

Lyris the Kitori•11/6/22, 5:28 PM

Silk works on android, iOS is partially there (but doesnt work on real hardware yet), and mac and windows work good

K

Khalid•11/6/22, 5:28 PM

sorry caps was on

K

Khalid•11/6/22, 5:28 PM

so can i do it or cant?

K

Khalid•11/6/22, 5:28 PM

should i try it

L

Lyris the Kitori•11/6/22, 5:28 PM

if you use MAUI, you cannot

K

Khalid•11/6/22, 5:28 PM

any recomendations

K

Khalid•11/6/22, 5:28 PM

i am

L

Lyris the Kitori•11/6/22, 5:28 PM

iirc Veldrid has a fork with MAUI support

LLyris the Kitori iirc Veldrid has a fork with MAUI support

K

Khalid•11/6/22, 5:29 PM

i tried working with it

K

Khalid•11/6/22, 5:29 PM

i didnt understand how to hang the backend to

K

Khalid•11/6/22, 5:29 PM

maui

L

Lyris the Kitori•11/6/22, 5:29 PM

¯\_(ツ)_/¯

L

Lyris the Kitori•11/6/22, 5:29 PM

if you can manage to get a gl context from maui

L

Lyris the Kitori•11/6/22, 5:29 PM

then silk would work

K

Khalid•11/6/22, 5:29 PM

someone sent me a git hub link

L

Lyris the Kitori•11/6/22, 5:29 PM

but we dont have the logic to do that, you'd have to do it yourself

K

Khalid•11/6/22, 5:29 PM

but every time i run it gives error

LLyris the Kitori but we dont have the logic to do that, you'd have to do it yourself

K

Khalid•11/6/22, 5:30 PM

logic like what

K

Khalid•11/6/22, 5:30 PM

?

L

Lyris the Kitori•11/6/22, 5:30 PM

idk

L

Lyris the Kitori•11/6/22, 5:30 PM

ive never used MAUI, i run linux

L

Lyris the Kitori•11/6/22, 5:30 PM

and MAUI has no linux support

K

Khalid•11/6/22, 5:30 PM

i see

LLyris the Kitori and MAUI has no linux support

K

Khalid•11/6/22, 5:30 PM

u think it will or not?

L

Lyris the Kitori•11/6/22, 5:30 PM

every project that has tried, has died out

L

Lyris the Kitori•11/6/22, 5:31 PM

so idk

K

Khalid•11/6/22, 5:31 PM

can u at least help me with veldrid or u busy or something

Is there any tutorials of programming on dx11+ on silk.net?
