This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGL2RenderingContext.texStorage3D()
method of the WebGL API specifies all levels of a three-dimensional texture or two-dimensional array texture.
Syntax
void gl.texStorage3D(target, levels, internalformat, width, height, depth);
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 number of texture levels. internalformat
- A
GLenum
specifying the texture store format. Possible values:gl.R8

[1] WebGL 2 is enabled by default in Firefox Nightly. To enable it in a release version of Firefox, set the preference webgl.enable-prototype-webgl2
to true
in about:config.
[2] To use an experimental implementation of WebGL 2 in Chrome, you have to start Chrome with the runtime flag --enable-unsafe-es3-apis
