The WebGL2RenderingContext.drawRangeElements() method of the WebGL API renders primitives from array data in a given range.
drawRangeElements(mode, start, end, count, type, offset)modeA GLenum specifying the type primitive to render. Possible values are:
gl.POINTS: Draws a single dot.gl.LINE_STRIP: Draws a straight line to the next vertex.gl.LINE_LOOP: Draws a straight line to the next vertex, and connects the last vertex back to the first.gl.LINES: Draws a line between a pair of vertices.gl.TRIANGLE_STRIPgl.TRIANGLE_FANgl.TRIANGLES: Draws a triangle for a group of three vertices.startA GLuint specifying the minimum array index contained in offset.
endA GLuint specifying the maximum array index contained in offset.
countA GLsizei specifying the number of elements to be rendered.
typeA GLenum specifying the type of the values in the element array buffer. Possible values are:
gl.UNSIGNED_BYTEgl.UNSIGNED_SHORTgl.UNSIGNED_INToffsetA GLintptr specifying an offset in the element array buffer. Must be a valid multiple of the size of the given type.
None (undefined).
mode is not one of the accepted values, a gl.INVALID_ENUM error is thrown.offset is a valid multiple of the size of the given type, a gl.INVALID_OPERATION error is thrown.count is negative, a gl.INVALID_VALUE error is thrown.gl.drawRangeElements(gl.POINTS, 0, 7, 8, gl.UNSIGNED_BYTE, 0);
