Web/API/WebGL2RenderingContext/texStorage2D

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

The WebGL2RenderingContext.texStorage2D() method of the WebGL API specifies all levels of two-dimensional texture storage.

Syntax

void gl.texStorage2D(target, levels, internalformat, width, height);

Parameters

target

A GLenum specifying the binding point (target) of the active texture. Possible values:

gl.TEXTURE_2D: A two-dimensional texture.
gl.TEXTURE_CUBE_MAP: A cube-mapped texture.

levels

A GLint specifying the number of texture levels.

internalformat

A GLenum specifying the texture store format. Possible values:

gl.R8
gl.R16F
gl.R32F
gl.R8UI
gl.RG8
gl.RG16F
gl.RG32F
gl.RG8UI
gl.RGB8
gl.SRGB8
gl.RGB565
gl.R11F_G11F_B10F
gl.RGB9_E5
gl.RGB16F
gl.RGB32F
gl.RGB8UI
gl.RGBA8
gl.SRGB8_APLHA8
gl.RGB5_A1
gl.RGBA4
gl.RGBA16F
gl.RGBA32F
gl.RGBA8UI

Unlike OpenGL 3.0, WebGL 2 doesn't support the following ETC2 and EAC compressed texture formats (see section 5.37 in the WebGL 2 spec). You might be able to enable them via the WEBGL_compressed_texture_etc extension, though.

gl.COMPRESSED_R11_EAC
gl.COMPRESSED_SIGNED_R11_EAC
gl.COMPRESSED_RG11_EAC
gl.COMPRESSED_SIGNED_RG11_EAC
gl.COMPRESSED_RGB8_ETC2
gl.COMPRESSED_RGBA8_ETC2_EAC
gl.COMPRESSED_SRGB8_ETC2
gl.COMPRESSED_SRGB8_ALPHA8_ETC2_EAC
gl.COMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2
gl.COMPRESSED_SRGB8_PUNCHTHROUGH_ALPHA1_ETC2

width

A GLsizei specifying the width of the texture.

height

A GLsizei specifying the height of the texture.

Return value

None.

Examples

gl.texStorage2D(gl.TEXTURE_2D, 1, gl.RGB8, 256, 256);
