TODO

Editor

Show some info on mouse over of blocks
Fast scrolling when zoomed out
Reconsider combining pipes when dragging/dropping/placing
No red outline when placing same object
Smooth camera movement
Don't allow deleting in multiple layers without moving the mouse
Don't scroll on C-s or C-a

Rendering

Highlight wind-wind interactions
Improve pillars
Handle shadow mapping on large maps
Line rendering does not correctly account for FOV!
Have pipes show the difference between wind in/out holes somehow

Gameplay

Campaign mode

Optimization

Figure out a way to use pareen without boxes
Render outlines as boxes instead of 12 lines
See if we need triple-buffering for update/draw threading
Some cheap culling heuristic
Don't use from_euler_angles for axis-aligned stuff
Particle rendering without geometry shaders
Wind LoD
Better streaming of instance and particle data
- Persistent mapping + triple buffering?
Precompute inverse transform for normals

Execution

Bug when flinging a blip up
Disallow blip moving through blip

Block ideas

Fixed-size blip buffer
Stateful left/right pipe
Explicit block for falling blips
Perhaps make funnel properties part of the pipe

UI

Replace imgui

Sound

Anything at all!

Level Ideas

Introductory

Only let through green
Flip color
Even/odd
Append green

Intermediate

Splitting input into two outputs
Splitting input into head/tail
Something about buffering?

Hard

Other

Revise TickTime, manipulating it is needlessly tedious
