TaSTT.git/Shaders, branch v0.10.1

Custom chatbox shader writes depth

2023-03-23T23:52:51+00:00

This fixes issues where the transparent corners of the textbox render in front of other materials, causing those other materials to skip rendering. * Update README.md with roadmap and avatar resource usage.

Reduce texture memory usage for English speakers

We used to populate 7 4k textures + 1 2k texture for all users. Now if the user has configured `bytes_per_char=1` in the Unity panel, we just populate a single 512x512 texture containing the first 128 ASCII characters. This reduces texture memory usage by 99.74%, from 134.67 MB to 340 KB.

Add hack to reduce outlines around emotes

2023-02-13T22:36:59+00:00

Don't render any part of an emote with alpha < 0.5. Improves visual clarity in the common case at the cost of generality. * Emotes now use physically-based shading. * Use round() to denoise shader parameters instead of floor()

Finish emotes

2023-02-13T22:36:25+00:00

Emotes require 2 bytes per char. They're encoded into the region [0xE000, infinity). The texture is 4k, and uses 1k vertical pixels per emote segment, for a maximum of 32 segments. * Reduce volume of noise indicator by 90%. Quiet is probably better. Might want to add a volume slider idk. * Bugfix: emotes without a transparency channel now work * Address a couple Unity performance complaints about the shader

Begin work adding emotes

2023-02-13T22:36:20+00:00

Done: * Users can add images to Fonts/Emotes/ * The basename of that image ('clueless.png' becomes 'clueless') is the keyword to make the image show up in game. * Fix a bug in the shader where letters on the 2nd texture and later would have UV outside of [0.0, 1.0] Not yet implemented: * transcribed words are encoded using emotes mapping

Shader now supports custom cubemap

Applied to both PBS and TaSTT shaders.

Do not use PBR shading on curve transparency

2023-02-01T06:00:49+00:00

Diffuse reflections can show up on this part.

Implement simple anti-aliasing

2023-02-01T03:35:44+00:00

Sample the texture up to 5 times using the algorithm shown in `aa_sample_algorithm.py`. Results are averaged together. * Redo dithering PRNG

Rework dithering

2023-01-31T16:31:24+00:00

I realized that ddx(i.uv.x) tells us how wide the current pixel is w/r/t UV coordinates. We can use this to implement a better form of dithering, which gets weaker as the viewer gets closer and stronger as they get farther. * Fine-tune mip map filtering based on play testing
