Web/API/WebGL2RenderingContext/copyTexSubImage3D

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

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

Syntax

void gl.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 nth 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.

Examples

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