Struct GlslMaterialBlock 

pub struct GlslMaterialBlock;

Generates GLSL source code for a uniform block that matches the layout of a PbrMaterial. Use this to keep CPU-side structs and shaders in sync.

Implementations

impl GlslMaterialBlock

pub fn uniform_block(binding: u32) -> String

Returns a GLSL uniform block declaration string that mirrors PbrMaterial. The binding parameter sets the UBO binding point.

pub fn sampler_uniforms(base_binding: u32) -> String

Returns GLSL sampler uniform declarations for all optional PBR textures.

pub fn read_material_fn() -> &'static str

Returns a GLSL function that reads all PBR inputs from the uniforms and textures above, and returns them in local variables with the given name prefix.

pub fn fragment_shader_source(ubo_binding: u32, tex_base: u32) -> String

Generate a complete minimal PBR fragment shader source that uses all of the blocks defined above.
