The WebGLRenderingContext.texImage3D()
method of the WebGL API specifies a three-dimensional texture image.
The WebGLRenderingContext.texImage3D()
method of the WebGL API specifies a three-dimensional texture image.

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 n-th mipmap reduction level.
internalformat
A GLint
specifying the color components in the texture. Possible values:
gl.ALPHA
: Discards the red, green and blue components and reads the alpha component. gl.RGB
: Discards the alpha components and reads the red, green and blue components. gl.RGBA
: Red, green, blue and alpha components are read from the color buffer. gl.LUMINANCE
: Each color component is a luminance component, alpha is 1.0. gl.LUMINANCE_ALPHA
: Each component is a luminance/alpha component.gl.R8

width
A GLsizei
specifying the width of the texture.
height
A GLsizei
specifying the height of the texture.
depth
A GLsizei
specifying the depth of the texture.
border
A GLint
specifying the width of the border. Must be 0.
format
A GLenum
specifying the format of the texel data. The correct combinations with internalformat
are listed in this table.
type
A GLenum
specifying the data type of the texel data. Possible values:
gl.UNSIGNED_BYTE
: 8 bits per channel for gl.RGBA
gl.UNSIGNED_SHORT_5_6_5
: 5 red bits, 6 green bits, 5 blue bits.gl.UNSIGNED_SHORT_4_4_4_4
: 4 red bits, 4 green bits, 4 blue bits, 4 alpha bits. gl.UNSIGNED_SHORT_5_5_5_1
: 5 red bits, 5 green bits, 5 blue bits, 1 alpha bit. gl.BYTE

(pixels must be null
) source
One of the following objects can be used as a pixel source for the texture:
srcData
A TypedArray
or a DataView
object.
offset
A GLintptr
byte offset into the WebGLBuffer
's data store. Used to upload data to the currently bound WebGLTexture
from the WebGLBuffer
bound to the PIXEL_UNPACK_BUFFER
target.
None (undefined
).
