WebGL2RenderingContext.texStorage2D

This is an experimental technology
Check 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

  • 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.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
