WebGL2RenderingContext: copyTexSubImage3D() method

The WebGL2RenderingContext.copyTexSubImage3D() method of the WebGL API copies pixels from the current WebGLFramebuffer into an existing 3D texture sub-image.

Syntax

js

copyTexSubImage3D(target, level, xoffset, yoffset, zoffset, x, y, width, height)

Parameters

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.

Return value

None (undefined).

Examples

js

gl.copyTexSubImage3D(gl.TEXTURE_3D, 0, 0, 0, 0, 0, 0, 16, 16);
