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);
