ludus::graphics::renderer::MaterialDescription¶

Struct

Copied unlit instance schema for the installed renderer_material.slang program. Color textures are linear RGBA8 or sRGB RGBA8; data/coverage formats reject.

Fields¶

Texture¶

rhi::TextureHandle ludus::graphics::renderer::MaterialDescription::Texture {}

Ready sampled RGBA8 texture; null uses the program's ready white fallback. Creation retains the exact texture view; caller may destroy its owner afterward.

Related types: rhi::TextureHandle

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

Tint¶

ludus::foundation::math::Vector4 ludus::graphics::renderer::MaterialDescription::Tint {1, 1, 1, 1}

Straight display-linear RGBA in [0,1]; Opaque requires alpha one.

Related types: ludus::foundation::math::Vector4

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

UvTransform¶

ludus::foundation::math::Vector4 ludus::graphics::renderer::MaterialDescription::UvTransform {1, 1, 0, 0}

UV scale XY and offset ZW, finite; authored UVs use top-left image orientation.

Related types: ludus::foundation::math::Vector4

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

Sampler¶

rhi::SamplerDescription ludus::graphics::renderer::MaterialDescription::Sampler {}

Independent immutable filter/address/mip state.

Related types: rhi::SamplerDescription

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

Alpha¶

MaterialAlpha ludus::graphics::renderer::MaterialDescription::Alpha = MaterialAlpha::Opaque

Scene ordering/depth contract.

Related types: MaterialAlpha

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

AlphaCutoff¶

ludus::foundation::float32 ludus::graphics::renderer::MaterialDescription::AlphaCutoff = 0.5F

Mask threshold in [0,1], relevant only to Masked; equal alpha survives.

Related types: ludus::foundation::float32

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/materials.hpp

Lod¶

ludus::foundation::float32 ludus::graphics::renderer::MaterialDescription::Lod = -1

-1 selects implicit derivative LOD; otherwise a finite initialized level [0,last]. Explicit LOD supports deterministic content previews, not automatic streaming.
