Roadmap

Follows are initial plans for future releases and then going back into time to previously completed milestones.

Stable Release Support and Functionality build-out Phase, 2023 onwards (underway)

Goal: Maintain the VulkanSceneGraph-1.0.x release series and work towards the next stable release VulkanSceneGraph-1.2 - expanding the VulkanSceneGraph and companion projects feature sets to address a wider range of uses

Discussion of new features:New Feature Development RoadMap for future VulkanSceneGraph-1.2 release and beyond

Completed tasks:

Current development tasks:

  • vsgQt support for Wayland

Future development tasks:

  • Support for shadows and environment maps in the Phong and PBR ShaderSets, and helper functions/classes for creating scene graphs that render shadow maps.
  • Character animation/skinning in standard.vert shaders used by Phong and ShaderSets?
  • Rewrite RayTracing classes to modernize them and bring them more inline with other core VSG classes.
  • Acceleration structures for CPU based geometry operations i.e. KdTree or similar to speed up intersection testing etc.
  • Multiview extension implementation
  • Noise function, CPU or GPU or both.
  • vsgQt multi window support
  • Support for integration with OpenGL/OSG applications via EXT_external_object & VK_KHR_external_memory

Core Development & Release Phase, 2019-2022 (completed)

Goal: Create the final class interfaces and implementation

Using the prototyping work as a guide implement the final scene graph library with the aim of creating a solid interface and implementation.

Completed tasks:

  • Development of final VSG Library.
  • Support for multi-threaded database paging.
  • Support for multi-threaded viewer, cull and dispatch traversals.
  • Support for multi-pass rendering.
  • Support for large scale whole world databases, with double support for scene graph transforms.
  • Development of add on libraries that provide:
    • Support for major image formats.
    • Support for major 3D model formats, including FBX, glTF.
    • Support for PBR shaders.
    • Support for Text rendering.
  • Development of test suite of programs and data.
  • Support for RTX Mesh shaders and ray tracing.
  • Scene graph level multi-bin support with bin sorting.
  • Support for Khronos ray tracing.
  • Memory allocator with support for grouping associated types
  • Positional state support to enable easier support of lighting, shadows, texture projection.
  • Matrix decomposition
  • Port to iOS
  • Unified state composer, shader set and cache
  • Update vsgXchange::Assimp to use the new state composer/shader set.
  • Support for wide and standard strings in vsg::Path.
  • Utilize vkEnumerateInstanceVersion
  • Update vsgImGui to latest
  • Improved support for dynamic scene graphs and dynamic views, dynamic descriptor pool reallocation
  • Refinement of API and implementation
  • Build relationships with application developers and involve them in testing
  • Create tutorial and example programs to illustrate how to use VSG
  • Test, debug, refine and release 1.0.0!
  • Update vsgXchange::OSG to use the new state composer/shader set.
  • Rewrite vsgQt handling of keyboard mapping
  • VulkanSceneGraph-1.0.0 stable release

Prototype Phase, October-December 2018 (completed)

Goal : Rapid prototyping of main classes, library and test applications to establish how the scene graph API will broadly look and work.

Prototype Phase Materials:

Exploration Phase, June-September 2018 (completed)

Goal : Establish which technologies and broad techniques to use

Learn and experiment with Vulkan, modern C++, and possible 3rd party dependencies. Experimenting with different approaches to object/scene graph design and implementation. Exploration Phase Materials :
