The WebGLRenderingContext.vertexAttribPointer() method of the WebGL API specifies the data formats and locations of vertex attributes in a vertex attributes array.


void gl.vertexAttribPointer(index, size, type, normalized, stride, offset);


A GLuint specifying the index of the vertex attribute that is to be modified.
A GLint specifying the number of components per vertex attribute. Must be 1, 2, 3, or 4.
A GLenum specifying the data type of each component in the array. Must be one of: gl.BYTE, gl.UNSIGNED_BYTE, gl.SHORT, gl.UNSIGNED_SHORT, gl.FLOAT.
A GLboolean specifying if fixed-point data values should be normalized (gl.TRUE) or are to converted to fixed point values (gl.FALSE) when accessed.
A GLsizei specifying the offset in bytes between the beginning of consecutive vertex attributes.
A GLintptr specifying an offset in bytes of the first component in the vertex attribute array. Must be a multiple of type.

Return value



gl.vertexAttribPointer(0, 3, gl.FLOAT, 0, 0, 12);
