WebGL2RenderingContext: copyTexSubImage3D() method
Available in workers
The copyTexSubImage3D() method of the WebGL2RenderingContext interface of the WebGL API copies pixels from the current WebGLFramebuffer into a 3D texture sub-image.
Syntax
copyTexSubImage3D(target, level, xoffset, yoffset, zoffset, x, y, width, height)
Parameters
target- : A
GLenumspecifying the binding point (target) of the active texture. Possible values:gl.TEXTURE_3D: A three-dimensional texture.gl.TEXTURE_2D_ARRAY: A two-dimensional array texture.
- : A
level- : A
GLintspecifying the level of detail. Level 0 is the base image level and level n is the n-th mipmap reduction level.
- : A
xoffset- : A
GLintspecifying the x offset within the texture image.
- : A
yoffset- : A
GLintspecifying the y offset within the texture image.
- : A
zoffset- : A
GLintspecifying the z offset within the texture image.
- : A
x- : A
GLintspecifying the x coordinate of the lower left corner where to start copying.
- : A
y- : A
GLintspecifying the y coordinate of the lower left corner where to start copying.
- : A
width- : A
GLsizeispecifying the width of the texture in texels.
- : A
height- : A
GLsizeispecifying the height of the texture in texels.
- : A
Return value
None (undefined).
Examples
