WebGLRenderingContext: attachShader() メソッド
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2015年7月.
WebGLRenderingContext.attachShader() は WebGL API のメソッドで、フラグメントか頂点のどちらかの WebGLShader を WebGLProgram にアタッチします。
構文
js
attachShader(program, shader)
引数
programshader-
フラグメントか頂点の
WebGLShader。
例
以下は既存のシェーダーを WebGLProgram にアタッチするコードです。
js
const program = gl.createProgram();
// 既に存在するシェーダーをアタッチ
gl.attachShader(program, vertexShader);
gl.attachShader(program, fragmentShader);
gl.linkProgram(program);
if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
const info = gl.getProgramInfoLog(program);
throw `WebGL プログラムをコンパイルできませんでした。 \n\n${info}`;
}
