The WebGLRenderingContext.texImage3D()
method of the WebGL API specifies a three-dimensional texture image.
Syntax
void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, GLintptr offset); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, HTMLCanvasElement source); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, HTMLImageElement source); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, HTMLVideoElement source); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, ImageBitmap source); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, ImageData source); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, ArrayBufferView? srcData); void gl.texImage3D(target, level, internalformat, width, height, depth, border, format, type, ArrayBufferView srcData, srcOffset);
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 level of detail. Level 0 is the base image level and level n is the nth 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

source
- One of the following objects can be used as a pixel source for the texture:
- offset
- A
GLintptr
byte offset into theWebGLBuffer
's data store. Used to upload data to the currently boundWebGLTexture
from theWebGLBuffer
bound to thePIXEL_UNPACK_BUFFER
target. -
Return value
None.
Examples
gl.texImage3D(gl.TEXTURE_3D, 0, // level gl.RGBA, // internalFormat 1, // width 1, // height 1, // depth 0, // border gl.RGBA, // format gl.UNSIGNED_BYTE, // type new Uint8Array([0xff, 0x00, 0x00, 0x00])); // data
