Applying a texture to a custom effect using DirectXTK results in the texture being stretched

Asked 2022-Feb-14 at 01:59

I'm trying to apply a custom effect using the DirectXTK. The effect is supposed to be an "unlit" shader with just one texture. But for some reason, the texture is stretched across the model. I looked in renderdoc and the texturecoordinates appear to be loaded correctly so i'm not sure what's going on.

Chuck Walbourn was correct. My issue was that I was normalizing my texture coordinates in the pixel shader. The correct code is return BaseColor.Sample(SampleType, vout.TexCoord);

You will have to read back the texture to the cpu with the ID3D11DeviceContext::Map API https://docs.microsoft.com/en-us/windows/win32/api/d3d11/nf-d3d11-id3d11devicecontext-map

You will get out a void* you will cast to uint32_t* which will point to the start of your data.

You need to get better a looking up the DirectX documentation, its really quite good documentation. There are a lot harder things you will need to find in the documentation if you keep doing 3D graphics.

How is constant buffer variables got matched between C++ code and shader code?

Asked 2021-Sep-11 at 23:57

I am learning D3D11 by myself. I am wondering how is variable in c++ got matched by variables in shader?

For example, from the tutorial of D3D11: https://docs.microsoft.com/en-us/windows/win32/direct3d11/overviews-direct3d-11-resources-buffers-constant-how-to

The layout of CBuffer in C++ is exact same as the layout in shader. However, in some game engines like Unity, shader variables can be placed in any order as long as I declare all of them. How is this achieved?

...

ANSWER

Answered 2021-Sep-08 at 03:12

I haven't dug into the implementation of how rendering engine automatically binds the shader variable to the layout of graphics pipeline. But here is my guess.

While game engine compiling shader codes, it will write some shader header infos including shader varaible's layouts.

This can be implemented by the tools like glslang. This kind of tool can convert shader source codes into abstract syntax tree(AST), which means the shader codes are parsed into many types of ast nodes, such as input attribute and output variable. At this time, it can assign a explicit layout to the input shader variables and save the layout in shader header.

While initializing the graphics pipeline, the pipeline layout can be created according to the shader header.

Above is just my guess of possible implementation.

WebGL Recreate Overlapping Triangles

Asked 2021-Sep-03 at 13:19

I'm trying to create a program without css that displays several overlapping triangles on a black background. Once I can get the triangles to display (like in the picture attached only with different colors), I need to implement either a z-buffer or a painter's algorithm; but first, I can't figure out what's wrong in the code below that they aren't displaying at all. I think it's an issue with my shaders perhaps?

In shader model 5, constant buffers are not object or variables, so no, you can't pass then as arguments to functions.

Your closest way is indeed to work with structs (and make sure that you use the struct both in the cbuffer declaration and as function input.
