Shaders/filters for different mood states implemented

[waackph]

Possible effects:

• turn down/up saturation
• turn down/up hue
• overlay a semi-transparent black or white (other possible solution to address change in colors) -> this can be done by ambient lighting
• add light sources (either with shader or overlay) -> lamp in room & sun shining through window

Todos:

• [x] Implement shaders (greyscale, noise, blur) in an isolated environment (bloom is optional)
• [ ] Implement shader logic to game (per object, post process on scene as texture)
• [ ] Change shader effects on mood change (depressed -> greyscale, bloom/blur -> manic)
• [ ] Use shader effect for mood transition (noise/distortion)
• [ ] Try different other shaders (e.g. reduce/increase saturation/hue depending on mood state) & decide which effects fit best
• [ ] Finish mood and mood-transition shaders
• [ ] Create light maps for all rooms (corridor, living room, kitchen/dining room)
• [ ] Blend room with light map via shader (https://github.com/manbeardgames/monogame-hlsl-examples/tree/master/source/Example04Simple2DLighting)
• [ ] (optional) create shadows with shader (https://slembcke.github.io/SuperFastHardShadows)

Continue with following

• Create a infinite background for experimenting: https://learn-monogame.github.io/tutorial/infinite-background-shader/
• Create wiggle effect as basis for other tutorials: https://digitalerr0r.net/2009/04/22/xna-shader-programming-tutorial-9-post-process-wiggle/
• Create the post processing effects (based on the wiggle tutorial), e.g. https://digitalerr0r.net/2009/04/22/xna-shader-programming-tutorial-12-post-process-noise/
• Create 2D Lighting (without shadows for now): https://github.com/manbeardgames/monogame-hlsl-examples/tree/master/source/Example04Simple2DLighting
• Continue with hard shadows: https://slembcke.github.io/SuperFastHardShadows
