Here lives all the VK specific code. It should be as similar as possible to the DX12 directory.

• base: All the basic code to manage and load textures/buffers/command buffers
• GLTF: Code to render the scene using different techniques
  • GLTFBBoxPass: renders just the bounding boxes of the objects
  • GLTFBDepthPass: creates optimized geometry, descriptor sets and pipelines for a depth pass. It also renders the pass and supports skinning.
  • GLTFPbrPass: same as above but for the forward PBR pass. (Credits go to the glTF-WebGL-PBR github project for its fantastic PBR shader.)
  • TexturesAndBuffers: It loads the texture and buffers from disk and uploads into video memory it also uploads the skinning matrices buffer.
• PostProc
  • PostProcCS/PostProcPS: that takes a shader and some inputs and draws a full screen quad (used by the effects below)
  • Bloom: combines the DownsamplePS and the Blur passes to create a Bloom effect. (All the credits go to Jorge Jimenez!)
  • BlurPS: takes a mip chain and blurs every mip element
  • DownSamplePS: takes a render target and generates a mip chain
  • SkyDome: loads a diffuse+LUT and a specular skydome cubemap. This is used for Image Based Lighting (IBL) and also for drawing a skydome.
  • SkydomeProc: draws a skydome procedurally using the Preetham Model. (Credits go to Simon Wallner and Martin Upitis.) TODO: Generate a diffuse cubemap for IBL.
  • ToneMapping: implements a number of tonemapping methods.
• Shaders
  • all the shaders used by the above classes
• Widgets
  • Axis: Renders an axis
  • WireFrameBox: Renders a box in wireframe
  • WireFrameSphere: Renders a sphere in wireframe
  • CheckerBoardFloor: as stated.

Note: All the code that may be common with DX12 is in src/common
