Shader Collection

Introduction

This is a collection of shaders written in HLSL using Evergine. The library provides a variety of shader effects to enhance the visual quality of your graphics applications. It includes implementations of popular effects such as Blinn-Phong, BRDF Microfacet, BRDF + IBL, IBL, etc.

Shaders

• Blinn-Phong: Implements the classic Blinn-Phong lighting model for realistic shading and highlights.
• BRDF Microfacet: Offers a microfacet-based BRDF (Bidirectional Reflectance Distribution Function) for accurate material rendering.
• IBL: Implements Image-Based Lighting (IBL) to achieve realistic reflections and lighting effects.
• BRDF + IBL: Combines BRDF with Image-Based Lighting (IBL) techniques for realistic and dynamic lighting.
• Equirectangular Reflections: Provides reflections based on equirectangular environment maps.
• TextureCube Reflections: Offers reflections using cube maps as environment maps.
• Fur Shells: Simulates fur or hair effects using shell rendering techniques.
• Explode Effect: Creates an explosion effect by manipulating vertex positions.
• Extrude Pyramid: Extrudes a pyramid shape from a base geometry.
• Extrude Triangles: Extrudes triangles along their normals to create a 3D effect.
• Flat Shading: Applies flat shading to achieve a low-polygon aesthetic.
• Fresnel: Implements Fresnel effects for reflective materials.
• Interior Mapping: Simulates the appearance of interiors behind windows or other surfaces.
• Parallax Corrected Cube Mapping: Provides improved cube map reflections with parallax correction.
• Normal Mapping: Enhances surface lighting and detail using normal maps.
• Parallax Mapping: Simulates depth on textured surfaces by offsetting texture coordinates.
• Parallax Occlusion Mapping: Enhances the depth simulation of Parallax Mapping with occlusion handling.
• Toon Shading: Applies a toon or cel-shading effect to achieve a cartoon-like rendering style.
• Translucency Shading: Simulates light passing through translucent materials for realistic rendering.
• Vertex Normals GS: Calculates vertex normals in the Geometry Shader stage for improved shading accuracy.
• Wireframe GS: Renders objects as wireframes using the Geometry Shader stage.
• WrapShading: Fast subsurface scattering by modulating the shading based on their orientation relative to the incident light.
