2026 Plan

  • Improve the graphics fidelity of the engine. Improve it a ton. It is one of the weakest points of the engine, and it needs work.
  • Improve upon the performance of the engine. While the engine is not slow, there are a lot of systems that need a performance boost.
  • Add a capabale GPU particle system with a wide variety of abilities for shaping the particles and controling everything about them.
  • Add the ability to render heightmaps, as well as interact with them on the physics level.
  • Add procedural generation tools. Math functions using the stb_perlin library, and components in the entity system to easily use proc-gen.

Update 0.4:

  • [] Performance v2.0
    • [] Optimize resource loading
      • [] Meshes/models: Use cgltf and meshoptimizer instead of bloated Assimp.
      • [] Textures: This needs to be confirmed, but textures are probably the most demanding resource to load.
      • [] Fonts: I'm not sure with this one as well, but fonts can be very demanding.
    • [] Custom memory pools
      • We need to consider creating memory pools to avoid memory allocations as much as possible.
      • The gfx backend and the renderers are especially in need of this. They allocate shit left and right.
      • [] Create a simple pool allocater and pass it into the various functions that need it.
      • [] Perhaps override the new and delete operator so that we can watch the allocations on the STL side as well?
      • Memory. Just think about memory.

Update 0.5:

  • [] Renderer: Beautify v2.0
    • This one is just a thinking exersice. We don't want to add every rendering technique under the sun to "beautify" the engine's look.
    • [] Diffuse irradiance IBL (at least)
    • [] Global illumination (GI)
    • [] Gaussian blur
    • [] Bloom integration
  • [] Renderer architecture
    • [] The current render pass system needs to go.
      • Either reform it completely or get rid of it for more "handmade" passes.
    • [] Instead, we can have "post-process" passes much similiar to the current pass system, except way simpler.
  • [] Resources
    • [] We need to get rid of the NBR conversion tool and instead have the conversion process happen in the engine itself.
    • [] Documentation
  • [] GPU Particles
    • [] GPU-based particle system, using compute shaders.
    • [] Have a lot of options to edit the shape, distribution, and gravity. Perhaps save it in a file?
    • [] Documentation
  • [] Animation 3.0
    • [] Add inverse kinematics
    • [] User channels/tracking jobs?
    • [] Additive and partial blending
  • [] Renderer: Extra primitives
    • [] More shapes like planes, capsules, and so on.
    • [] Decal rendering
    • [] Add noise functions to the math library
    • [] Terrain rendering and procedural generation (terrain generation using stb_perlin and loading from heightmap)
    • [] Documentation

BUGS:

  • (Renderer): Capsules cannot be rendererd. Need to render those for debug purposes.

  • (Renderer): Spheres are not so perfect. Fix that.

  • Check all of the TODO, FIX, and TEMP in the codebase.
