albedo | Albedo 是一个Java企业应用开源框架，使用经典技术组合（SpringBoot2x、MyBatis、Vue），包括核心模块如：组织机构、角色用户、权限授权、数据权限、代码生成、定时任务等。 | Object-Relational Mapping library

This is a function template you declared:

For example a straightforward approach provided that each path in the vector has the extension .png can look for example the following way as it is shown in the demonstrative program below.

For ALPHA and ALBEDO: ALBEDO = a.xyz; is correct. For a.w, usually you would do this: ALPHA = a.w;. However, in this case, it appears that a.w is always 1. So there is no point.

I'll pick on the rest of the code. Keep in mind that I do not know how it should look like, nor have any idea of the texture for the sampler2D (I'm guessing noise texture, seamless).

Check your render mode. Being from ShaderToy, there is a chance you want render_mode unshaded;, which will make lights not affect the material. see Render Modes.

For ease of use, You can use hints. In particular, Write the tint color like this:

What you could do is go through the values of of your cad_list

In second pass, depth attachment description, it "loads" image in undefined state:

As with all GLSL extensions, you must explicitly enable them. However, you have a more interesting problem: bindless texturing cannot be used with SPIR-V. What you want to do is only possible if you feed the GLSL directly to OpenGL, without the SPIR-V intermediary.

Vulkan does not support bindless textures; you need to use arrays of samplers to get an equivalent effect. And OpenGL doesn't support GL_EXT_scalar_block_layout. So the code you're writing cannot be used by any graphics system.

I don't recognize a conceptual error. What do you get when you integrate the spectral direct irradiance? I'd expect to recover the sw_dr broadband value. Something to check. The line of code that calculates uvi looks odd. sw_dr from total_irrad is a Series, sw_dr(λ[280:400]) indicates that sw_dr is a function.

Properties of your Sphere class are readonly, you should do them like below ({get;set;}):

To get the world position of your pixel in the fragment shader you have to pass it through your vertex and geometry shader:

vertex => geometry
