IslandRenderer

CSC8502 course work

• Compiled binary can be downloaded at https://github.com/rejewl/IslandRenderer

How to control

• Press O to start/stop camera animation.
• Press L to start/stop day/night loop.

Features

• Compiled with win10 sdk 10.0.19041.0 and build tool v142
• Using defered shading.
• Only calculate shadow for the directional light.
• Have day/night loop.
• Have a camera keyframe animation.
• Using scene graph.
• Using frustum to cull primitives and point lights.
• Draw skybox after combine frame buffers.
• Draw transparent objects after skybox.
• Limited support for GLTF 2.0 (Only reads meshes & materials in file)
• GLTF/GLB loader is base on tinygltf.(https://github.com/syoyo/tinygltf)
• Using Physical Base Rendering.

New in NCLGL

• SOIL library removed.(Because of conflicting with std_image)
• ReMaterial: Base class for all object materials, contains a shader pointer & shader params.
• RePrimitive: Class for renderable object, contains a Mesh pointer & ReMaterial pointer.
• ReFrustum: Almost the same as Frustum class described in tutorial.
• ReFrustumObject: Base class for objects in Frustum Culling.
• ReDLight: Directional light class. Conatins light direction, colour, strength & distance(To determine where to place the shadow camera). Contains a Quad primitive to render in defered shading.
• ReSceneNode: Only handles transform, have multiple components.
• ReNodeComponent: Base class for components held by ReSceneNode.
  • RePrimitiveComponent: Contains a RePrimitive pointer. Base class for renderable objects in Scene Graph. Should be added to one ReSceneNode.
  • RePointLightComponent: Contains a RePrimitive pointer for drawing point light in defered shading. Contains light position, colour & radius. Should be added to one ReSceneNode.
• ReFrameBuffer: Base class for using FBO.
  • ReLightBuffer: Contains one light diffuse texture & one light specular texture.
  • ReSceneBuffer: Contains one base colour texture, one normal texture, one emissive texture, one metallic roughness texture & one depth texture.
    • metallic roughness texture: r->metallic, g->roughness, b->ambient occlution
  • ReShadowBuffer: Contains one depth texture.
