"Read-write and read-only storage textures are not allowed by webgpu, they require the native only feature TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES."

"Reading from a texture in a compute shader is extremely useful, surely there must a way to accomplish this in some other way."

"Edit:

I am writing a raytracer eerily similar to this one.
https://github.com/jgrazian/wgpu-raytracer.

And this used to be possible in the past."

英文:

I am trying to read (and write) to a texture in my compute shader. And getting the following message:

Read-write and read-only storage textures are not allowed by webgpu, they require the native only feature TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES

Reading from a texture in a compute shader is extremely useful, surely there must a way to accomplish this in some other way.

I am writing a raytracer eerily similar to this one.

在计算着色器中绑定纹理为普通Texture，然后使用textureLoad进行纹理读取是可能的：https://github.com/gfx-rs/wgpu/issues/2735

英文:

Reading from a texture in a compute shader is possible when binding the texture as a normal Texture (not as a StorageTexture) and then usingtextureLoad on it: https://github.com/gfx-rs/wgpu/issues/2735
