Hey guys.
Im trying implement realistic NVG.
If there any ideas how to implement it easier I will be glad to hear.
What already done:
- NVG works only in the monocular area without affecting peripheral vision, just like real NVG tubes in front of eye.
- Red turns white as the wave is close to infra-red
- Anything closer than a meter has a strong defocus
What I want to add:
- Modularity, the ability to choose a monocular or binocular glasses (if implement through the post process)
- Fake infrared spectrum, for realistic IR illumination, weapon red dot sights, lasers and IR reflective materials.
- Bloom for bright sources
- Optimization -_- especially for blur. (spiral blur based on depth map)
I made two versions, as a post process material and as surface material.
Cons of the post process material: the material is duplicated in both eyes, I can’t make a monocular system where the effect will work in one eye.
Pros: all translucent sprites will work correctly since im using scene texture.
Cons of the surface plane in front of the camera: jitters when FPS dropping and issue with displaying decals behind a nvg plane.
Pros: you can choose on which eye you want nvg effect.
Generally there are a couple of questions.
- Is it possible to regulate the post process for each eye separately for VR?
- How can you cheaply implement bloom in a material?
- is it possible to make a new channel for materials? For example, if Id like to make effect of a thermal image or make realistic infrared range, it will be impossible without additional texture channel of heat emission.
