我们再使用gl.bufferData将类型化后的数组复制到缓冲区中,最后一个参数gl.STATIC_DRAW提示 WebGL 我们不会频繁改变缓冲区中的数据,WebGL 会根据这个参数做一些优化处理。这部分属于初始化代码,在后续的渲染过程中,不会再次执行。 这里有个很重要的方法gl.vertexAttribPointer。这个方法决定目标属性如何从缓冲区 buffer...

constcanvas =document.querySelector('canvas') constbeam =newBeam(canvas) 然后我们用beam.shader来实例化着色器,这里的MyShader稍后再说: constshader = beam.shader(MyShader) 着色器准备好之后,就是准备资源了。为此我们需要使用beam.resourceAPI 来创建...
gl.bufferData(gl.ELEMENT_ARRAY_BUFFER, indices, gl.STATIC_DRAW); 最后调用gl.drawElements方法进行绘制。这里要传入 indices 数组的长度,WebGL 就会读取索引值得到对应的顶点信息去一个个绘制三角形啦。 gl.drawElements(gl.TRIANGLES, indices.length, gl.UNSIGNED_BYTE, 0); ...
