TextureSlot

Description

Names one of the five texture slots of a PBR Material, the maps glTF 2.0 defines for metallic-roughness materials.

Each slot and the setter that binds its texture:

• BaseColor, which Material::base_color_texture binds
• MetallicRoughness, which Material::metallic_roughness_texture binds
• Normal, which Material::normal_texture binds
• Occlusion, which Material::occlusion_texture binds
• Emissive, which Material::emissive_texture binds

Each slot samples its own UV set through its own transform. Material::texture_uv picks the set, and Material::texture_transform sets the transform. A glTF file loaded with Scene::load sets both from each texture’s texCoord and KHR_texture_transform.

Example

Rust

use fragmentcolor::{Material, TextureSlot};

let material = Material::pbr()
  .texture_uv(TextureSlot::Occlusion, 1)?
  .texture_transform(TextureSlot::Normal, [0.0, 0.0], [4.0, 4.0], 0.0)?;

JavaScript

import { Material, TextureSlot } from "fragmentcolor";

const material = Material.pbr().textureUv(TextureSlot.Occlusion, 1).textureTransform(TextureSlot.Normal, [0.0, 0.0], [4.0, 4.0], 0.0);

Python

from fragmentcolor import Material, TextureSlot

material = Material.pbr().texture_uv(TextureSlot.Occlusion, 1).texture_transform(TextureSlot.Normal, [0.0, 0.0], [4.0, 4.0], 0.0)

Swift

import FragmentColor

let material = try Material.pbr().textureUv(TextureSlot.occlusion, 1).textureTransform(TextureSlot.normal, [0.0, 0.0], [4.0, 4.0], 0.0)

Kotlin

import org.fragmentcolor.*

val material = Material.pbr().textureUv(TextureSlot.OCCLUSION, 1u).textureTransform(TextureSlot.NORMAL, listOf(0.0f, 0.0f), listOf(4.0f, 4.0f), 0.0f)
