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.
xoffset
A GLint
specifying the x offset within the texture image.
yoffset
A GLint
specifying the y offset within the texture image.
zoffset
A 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.
width
A GLsizei
specifying the width of the texture.
height
A GLsizei
specifying the height of the texture.
None (undefined
).
js
gl.copyTexSubImage3D(gl.TEXTURE_3D, 0, 0, 0, 0, 0, 0, 16, 16);
