WebGLRenderingContext.vertexAttribPointer()

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

Syntax

void <var>gl</var>.vertexAttribPointer(<var>index</var>, <var>size</var>, <var>type</var>, <var>normalized</var>, <var>stride</var>, <var>offset</var>);

Parameters

index

A GLuint specifying the index of the vertex attribute that is to be modified.

size

A GLint specifying the number of components per vertex attribute. Must be 1, 2, 3, or 4.

type

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.FIXED, gl.FLOAT.

normalized

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.

stride

A GLsizei specifying the offset in bytes between the beginning of consecutive vertex attributes.

offset

A GLintptr specifying an offset in bytes of the first component in the vertex attribute array. Must be a multiple of type.

Return value

None.

Examples

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