AMD FidelityFX™ Cauldron Framework is a framework library for rapid prototyping using either the Vulkan® or DirectX® 12 APIs.

• Fast glTF 2.0 file loader.

  • Animation for cameras, objects, skeletons, and lights.
  • Skinning:
    • Baking skinning into buffers (DirectX®12 only).
  • Rendering techniques:
    • Motion vectors.
    • Depth pass only.
    • PBR Materials:
      • Metallic-roughness.
      • Specular-glossiness (KHR_materials_pbrSpecularGlossiness).
    • Lighting (KHR_lights_punctual extension):
      • Point, directional, and spot lights (with up to four shadow maps).
      • Image-based Lighting (IBL) CubeMaps.
  • Shadow techniques:
    • Shadow maps (PCF).

• Configurable GBuffer supported techniques:

  • Full forward.
  • Motion vectors.
  • Normals.
  • Depth.
  • Specular-roughness.
  • Diffuse-alpha.

• Postprocessing:

  • TAA.
  • Bloom.
  • HDR/Tonemapping.

• Texture Loaders for DDS, JPEG, and PNG formats.

  • MIPMap generation for powers-of-two textures.

• In-app user interface using Dear ImGui.

• Rendering Resource Management:

  • Command Buffer ring.
  • Timestamp queries.
  • Memory Heap Manager (Linear Allocator).
  • Static buffers for VB/IB/CB with suballocation support.
  • Dynamic buffers for VB/IB/CB using a ring buffer.

• Debug Rendering:

  • Bounding box render.
  • Light frustum render.
  • Wireframe render.

• Window management and swapchain creation:

  • Fullscreen/Windowed modes and HDR handling.

• Support for DXC/SM6.x (also on Vulkan®).

• FreeSync™ Premium Pro HDR support.

• Shader binary and PSO caching.

• Multithreading loading and creation of resources:

  • Textures and MIPMap generation.
  • Shader compilation.
  • Pipeline creation.

• VK extensions in-app support.
