WebGL2RenderingContext.copyTexSubImage3D()
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
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.
level- A
GLintspecifying the level of detail. Level 0 is the base image level and level n is the nth mipmap reduction level. xoffset- A
GLintspecifying the x offset within the texture image. yoffset- A
GLintspecifying the y offset within the texture image. zoffset- A
GLintspecifying the z offset within the texture image. x- A
GLintspecifying the x coordinate of the lower left corner where to start copying. y- A
GLintspecifying the y coordinate of the lower left corner where to start copying. width- A
GLsizeispecifying the width of the texture. height- A
GLsizeispecifying the height of the texture.
Return value
None.
Examples
gl.copyTexSubImage3D(gl.TEXTURE_3D, 0, 0, 0, 0, 0, 0, 16, 16);
