なんか.appじゃなくてびっくり

code:a

taiseiue@lily ShaderBoi % ./sboi

Error: no project file specified. either in config or as arg

ふむ..?

help

code:a

taiseiue@lily myshader % ./sboi --help

ShaderBoi

Options:

-i, --in shader to run: ID or full url

file

--cfg path to config file (ShaderBoi.ron)

--vr use mainVR instead of mainImage, to render in 360°

--stereo rendering mode:

mono|top-bottom|left-right|right-left|anaglyph

--ipd interpupillary distance (distance between pupils), only

relevant in stereo rendering

-s, --res override project resolution:

WxH|st|360p|sd|480p|md|720p|hd|4k|8k|16k

-r, --fps frame rate

-a, --audio path to audio input file

-m, --midi path to midi input file or name of midi input port

-c, --refetch clear cached version of shaders in scene, refetch

-t, --time time offset in seconds (float)

-d, --skipbeats time offset for midi file in beats (float)

-f, --fov set horz FOV (in degrees) for perspective projection.

default is 90°

-p, --invproj invert projection mode (default: perspective proj for live,

equirectangular for recording)

-V, --version print version info and exit

--help display usage information

Commands:

rec record video

fin finalize video with audio and metadata

inj inject 360° metadata into video file

dl download and unpack shader (extract code of render passes

into separate .frag files)

ul upload given shader to shadertoy (to save changes after

local editing)

pkg package unpacked shader back into one json file, for

manually importing it on shadertoy

genproj create new project folder containing a project.ron file

based on the given args

new create a new shader on shadertoy (with new id), download and

unpack it

audio-inputs list available audio input devices

cam-list list available camera devices (to use as shader input)

cam-opts list options (resolution, fps) for given camera

ふむふむ

一旦プロジェクト作成やってみる

code:a

taiseiue@lily ShaderBoi % ./sboi genproj myproj

なんかshadertoryのIDをベースにつくるらしい?

これをベースにやる

code:a

Error: fetch_shader(tlVGDt)

Caused by:

0: fetch_json_shader(tlVGDt)

だめです

しょうがないので手動

もっともらしいやつを生成してもらった

code:a

$ mkdir myproj

code:myproj/main.frag

void mainImage(out vec4 fragColor, in vec2 fragCoord)

{

vec2 uv = fragCoord / iResolution.xy;

float bass = texture(iChannel0, vec2(0.01, 0.25)).x;

vec3 col = vec3(uv, 0.5);

col += bass * 2.0;

fragColor = vec4(col, 1.0);

}

code:myproj/project.ron

(

shaders: [

(

name: "Image",

path: "main.frag",

inputs: [

channel: 0,

kind: "audio",

),

],

)

なんかどれでもsyntax errorになって使いかた不明なので塩漬け
