Objectives?

[mtao]

This library is to provide a variety of tools for miscellaneous geometry processing / simulation tasks or projects, but it needs some direction to be able to say that it has any real utility.

It'd be good to visualize geometry / statistics on geometry. meshlab or paraview are really powerful for viewing, but lack customizabilty or editing / seem hard to customize. igl/polyscope work well but I want to be able to build more complex visualizations / further decouple the render pipeline from computation (using Qt signal/slots for now, but perhaps some other message passing mechanism in tehfuture).

• Mesh visualization
  • Qt frontend
  • GLFW / imgui frontend
  • OpenGL backend (for initial bootstrapping)
    • QtOpenGL (basic bootstrapping / testing shaders)
  • Vulkan backend
    • Qt Entrypoint
    • Vulkan-Hpp Entrypoint
  • Useful shaders
    • Phong
    • Scalar field rendering
    • Vector field rendering
    • Shading Pass
    • Fluid particle rendering https://dl.acm.org/doi/10.1145/1507149.1507164
    • Polynomial fields

There are two basic mesh representations I want to experiment with here:

• igl/matlab style blocks
  • not to be used for navigation, good for rendering / I/O?
• Local dart representation using mtao/LDart

It'll be generally useful to be able to input various types of geometry

• Mesh I/O
  • OBJ I/O
  • PLY I/O
  • MSH I/O
    • Plug in with qnzhou/mshio
  • alembic I/O (yes this is a scene format)
    • Plug in with alemgic/alembic
    • Accurately render a subset
  • gltf I/O (yes this is a scene format)
    • Maybe use tinygltf, but have encountered some offset alignment issues in the way it handles glb files?
    • Render GLTF geometry with materials

Different simulation tools / geometry processing need solvers. I want to implement a few things myself

• Solvers
  • Linear
    • Gauss-seidel
    • Jacobi
    • Conjugate Gradient
      • Preconditioners
        • Jacobi
        • MIC0
    • Multigrid
