method of the WebGL API renders primitives from array data in a given range.
js
drawRangeElements(mode, start, end, count, type, offset)
mode
A 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_STRIP
gl.TRIANGLE_FAN
gl.TRIANGLES
: Draws a triangle for a group of three vertices.start
A GLuint
specifying the minimum array index contained in offset
.
end
A GLuint
specifying the maximum array index contained in offset
.
count
A GLsizei
specifying the number of elements to be rendered.
type
A GLenum
specifying the type of the values in the element array buffer. Possible values are:
gl.UNSIGNED_BYTE
gl.UNSIGNED_SHORT
gl.UNSIGNED_INT
offset
A 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.js
gl.drawRangeElements(gl.POINTS, 0, 7, 8, gl.UNSIGNED_BYTE, 0);
