Frag

Frag 模块。在 Rust 中编写片段着色器，可以跳过样板代码，直接编写片段着色器。例如，在编写光线追踪着色器时很有用。

特性

• 组合多个部分或文件的着色器
• 实时编码：当文件更新时进行更新
• 键盘控制时间
• 分辨率无关：渲染和显示可以分别使用不同的分辨率。可以用于拉伸、像素化或抗锯齿
• 使用 FFMPEG 渲染 MP4
• 将当前帧保存为 PNG 图片

控制

• 空格：暂停/恢复时间和渲染
• 左键（按住）：后退时间
• 右键（按住）：前进时间
• 下键：将时间设置为 0
• PageDown：后退 5 秒
• PageUp：前进 5 秒

待办事项

• 后处理片段着色器可访问

示例

实时编码示例，具有像素艺术风格

use frag::*;
let streamer = shader::ShaderStreamer::new()
    .with_file("lib.glsl")
    .with_file("shader.glsl");
FragConf::new()
    .with_window_width(1600)
    .with_window_height(900)
    .with_canvas_width(320)
    .with_canvas_height(180)
    .with_pixelate(true)
    .with_streamer(streamer)
    .run_live().expect("Could not run.");

渲染到视频的示例

use frag::*;
let streamer = shader::ShaderStreamer::new()
    .with_file("lib.glsl")
    .with_file("shader.glsl");
FragConf::new()
    .with_window_width(1600)
    .with_window_height(900)
    .with_streamer(streamer)
    .into_ffmpeg_renderer()
    .with_framerate(30)
    .with_crf(20)
    .with_preset(Preset::Slow)
    .with_tune(Tune::Animation)
    .with_length(600)
    .with_output("render.mp4")
    .render().expect("Could not render.");
