The WebGLRenderingContext.attachShader() method of the WebGL API attaches either a fragment or vertex WebGLShader
to a WebGLProgram
.
The WebGLRenderingContext.attachShader() method of the WebGL API attaches either a fragment or vertex WebGLShader
to a WebGLProgram
.
js
attachShader(program, shader)
program
A WebGLProgram
.
shader
A fragment or vertex WebGLShader
.
The following code attaches pre-existing shaders to a WebGLProgram
.
js
const program = gl.createProgram(); // Attach pre-existing shaders gl.attachShader(program, vertexShader); gl.attachShader(program, fragmentShader); gl.linkProgram(program); if (!gl.getProgramParameter(program, gl.LINK_STATUS)) { const info = gl.getProgramInfoLog(program); throw `Could not compile WebGL program. \n\n${info}`; }
