js
copyTexSubImage3D(target, level, xoffset, yoffset, zoffset, x, y, width, height)
target A GLenum specifying 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.level A GLint specifying the level of detail. Level 0 is the base image level and level n is the n-th mipmap reduction level.
xoffsetA GLint specifying the x offset within the texture image.
yoffsetA GLint specifying the y offset within the texture image.
zoffsetA GLint specifying the z offset within the texture image.
x A GLint specifying the x coordinate of the lower left corner where to start copying.
y A GLint specifying the y coordinate of the lower left corner where to start copying.
widthA GLsizei specifying the width of the texture.
heightA GLsizei specifying the height of the texture.
None (undefined).
js
gl.copyTexSubImage3D(gl.TEXTURE_3D, 0, 0, 0, 0, 0, 0, 16, 16);
