Leveling Up glTF Rendering in CesiumJS: PBR Improvements and …
2024年10月31日 · glTF 2.0 introduced physically based rendering (PBR) as a core feature, allowing for a simple, standard set of parameters to simulate real-world lighting interactions, materials, and surface properties.
Richer Materials with glTF Specular Glossiness in CesiumJS – Cesium
2018年10月22日 · glTF’s physically based rendering (PBR) material models define how a surface responds to light, e.g., how reflective or dull it is. As opposed to glTF’s built-in metallic-roughness model, the specular-glossiness extension can represent a broader range of materials by exposing more parameters, such as the specular color.
Tour of the New glTF Architecture in CesiumJS – Cesium
2022年10月5日 · For example, all glTF materials follow the same physically-based rendering (PBR) algorithm. The main difference is determining which textures and other uniforms to enable based on the glTF material settings.
Cesium Sandcastle
The Cesium Sandcastle provides an interactive environment for testing Cesium code.
PBR roadmap · Issue #5423 · CesiumGS/cesium - GitHub
2017年6月5日 · Idea for applying PBR to geospatial: Altering the metallic and roughness of a model at runtime to achieve certain results, For example, one can add highlights or rim lights to a model to represent selection by manipulating the metallic and roughness parameters.
Cesium 给大量建筑贴上PBR纹理 - CSDN博客
2024年12月5日 · 在Cesium中使用PBR（物理基础渲染）纹理给大量建筑物贴图时，TilesBuilder 是一个常用的图形化工具，它可以将原始数据转换成Cesium支持的 3D Tiles 格式。 如果你的数据源是 SHP （Shapefile）格式， TilesBuilder 同样能够帮助你生成带有PBR纹理的瓦片数据。
Add support for glTF KHR_materials_clearcoat extension #11995 - GitHub
The KHR_materials_clearcoat extension extends the PBR metallic roughness model to enable layering of a clear coating on top of an existing material. This clear coating can provide more realistic rendering of objects such as cars with a two-layered coating, where the color comes from the underlying layer.
KHR_materials_pbrSpecularGlossiness - glTF
The PBR specular-glossiness extension can be used along with PBR metallic-roughness material model in glTF to enable support for both PBR workflows. Specular-glossiness can represent a broader range of materials compared to metallic-roughness.
The CesiumJS Roadmap – Cesium
2021年3月23日 · glTF’s PBR Next initiative has brought together the world’s experts on Physically-Based Rendering (PBR) to advance glTF’s material representation from metal-roughness and specular-gloss to support a wide array of new visual effects such as clearcoat, transmission, and volumetric efforts.
Cesium着色器的创意和方法(四——模型光照渲染）_cesium 有灯 …
2024年11月7日 · 其中 PBR Neutral Tonemapping 是一种在物理基础渲染（PBR）工作流程中用于光照和色彩管理的技术，它旨在保持图像的真实感和色彩一致性。 它主要涉及到将场景的线性光照数据转换为适合显示设备（如显示器或电视）能够呈现的最终图像的过程。 Neutral Tonemapping 的目标是提供一个色调映射方案，使得渲染出的图像在不同的光照条件下表现出自然和令人满 …
