WebGL2RenderingContext.texStorage2D()

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.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.
level
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.RGUI
  • gl.RGB8
  • gl.SRGB8
  • gl.RGB565
  • gl.R11F_G11F_B10F
  • gl.RGB9_E5
  • gl.RGB16F
  • gl.RGB32F
  • gl.RGB8UI
  • gl.RGBA8
  • gl.SRGB_APLHA8
  • gl.RGB5_A1
  • gl.RGBA4444
  • gl.RGBA16F
  • gl.RGBA32F
  • gl.RGBA8UI
  • 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.
