NAME
glTexImage3D - specify a three-dimensional texture image
C SPECIFICATION
void glTexImage3D(GLenum target, GLint level, GLint internalFormat, GLsizei width, GLsizei height,
GLsizei depth, GLint border, GLenum format, GLenum type, const GLvoid * data);
PARAMETERS
target
Specifies the target texture. Must be one of GL_TEXTURE_3D, GL_PROXY_TEXTURE_3D, GL_TEXTURE_2D_ARRAY
or GL_PROXY_TEXTURE_2D_ARRAY.
level
Specifies the level-of-detail number. Level 0 is the base image level. Level n is the n th mipmap
reduction image.
internalFormat
Specifies the number of color components in the texture. Must be one of base internal formats given
in Table 1, one of the sized internal formats given in Table 2, or one of the compressed internal
formats given in Table 3, below.
width
Specifies the width of the texture image. All implementations support 3D texture images that are at
least 16 texels wide.
height
Specifies the height of the texture image. All implementations support 3D texture images that are at
least 256 texels high.
depth
Specifies the depth of the texture image, or the number of layers in a texture array. All
implementations support 3D texture images that are at least 256 texels deep, and texture arrays that
are at least 256 layers deep.
border
This value must be 0.
format
Specifies the format of the pixel data. The following symbolic values are accepted: GL_RED, GL_RG,
GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, GL_RED_INTEGER, GL_RG_INTEGER, GL_RGB_INTEGER, GL_BGR_INTEGER,
GL_RGBA_INTEGER, GL_BGRA_INTEGER, GL_STENCIL_INDEX, GL_DEPTH_COMPONENT, GL_DEPTH_STENCIL.
type
Specifies the data type of the pixel data. The following symbolic values are accepted:
GL_UNSIGNED_BYTE, GL_BYTE, GL_UNSIGNED_SHORT, GL_SHORT, GL_UNSIGNED_INT, GL_INT, GL_FLOAT,
GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5,
GL_UNSIGNED_SHORT_5_6_5_REV, GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV,
GL_UNSIGNED_SHORT_5_5_5_1, GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8,
GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, and GL_UNSIGNED_INT_2_10_10_10_REV.
data
Specifies a pointer to the image data in memory.
DESCRIPTION
Texturing maps a portion of a specified texture image onto each graphical primitive for which texturing
is enabled. To enable and disable three-dimensional texturing, call glEnable() and
glDisable with argument GL_TEXTURE_3D.
To define texture images, call glTexImage3D. The arguments describe the parameters of the texture image,
such as height, width, depth, width of the border, level-of-detail number (see glTexParameter()), and
number of color components provided. The last three arguments describe how the image is represented in
memory.
If target is GL_PROXY_TEXTURE_3D, no data is read from data, but all of the texture image state is
recalculated, checked for consistency, and checked against the implementation's capabilities. If the
implementation cannot handle a texture of the requested texture size, it sets all of the image state to
0, but does not generate an error (see glGetError()). To query for an entire mipmap array, use an image
array level greater than or equal to 1.
If target is GL_TEXTURE_3D, data is read from data as a sequence of signed or unsigned bytes, shorts, or
longs, or single-precision floating-point values, depending on type. These values are grouped into sets
of one, two, three, or four values, depending on format, to form elements. Each data byte is treated as
eight 1-bit elements, with bit ordering determined by GL_UNPACK_LSB_FIRST (see glPixelStore()).
If a non-zero named buffer object is bound to the GL_PIXEL_UNPACK_BUFFER target (see glBindBuffer())
while a texture image is specified, data is treated as a byte offset into the buffer object's data store.
The first element corresponds to the lower left corner of the texture image. Subsequent elements progress
left-to-right through the remaining texels in the lowest row of the texture image, and then in
successively higher rows of the texture image. The final element corresponds to the upper right corner of
the texture image.
format determines the composition of each element in data. It can assume one of these symbolic values:
GL_RED
Each element is a single red component. The GL converts it to floating point and assembles it into an
RGBA element by attaching 0 for green and blue, and 1 for alpha. Each component is clamped to the
range [0,1].
GL_RG
Each element is a red and green pair. The GL converts each to floating point and assembles it into an
RGBA element by attaching 0 for blue, and 1 for alpha. Each component is clamped to the range [0,1].
GL_RGB, GL_BGR
Each element is an RGB triple. The GL converts it to floating point and assembles it into an RGBA
element by attaching 1 for alpha. Each component is clamped to the range [0,1].
GL_RGBA, GL_BGRA
Each element contains all four components. Each component is clamped to the range [0,1].
If an application wants to store the texture at a certain resolution or in a certain format, it can
request the resolution and format with internalFormat. The GL will choose an internal representation that
closely approximates that requested by internalFormat, but it may not match exactly. (The representations
specified by GL_RED, GL_RG, GL_RGB, and GL_RGBA must match exactly.)
internalFormat may be one of the base internal formats shown in Table 1, below

If the internalFormat parameter is one of the generic compressed formats, GL_COMPRESSED_RED,
GL_COMPRESSED_RG, GL_COMPRESSED_RGB, or GL_COMPRESSED_RGBA, the GL will replace the internal format with
the symbolic constant for a specific internal format and compress the texture before storage. If no
corresponding internal format is available, or the GL can not compress that image for any reason, the
internal format is instead replaced with a corresponding base internal format.
If the internalFormat parameter is GL_SRGB, GL_SRGB8, GL_SRGB_ALPHA, or GL_SRGB8_ALPHA8, the texture is
treated as if the red, green, blue, or luminance components are encoded in the sRGB color space. Any
alpha component is left unchanged. The conversion from the sRGB encoded component c s to a linear
component c l is:
c l = { c s 12.92 if c s ≤ 0.04045 ( c s + 0.055 1.055 ) 2.4 if c s > 0.04045
Assume c s is the sRGB component in the range [0,1].
Use the GL_PROXY_TEXTURE_3D target to try out a resolution and format. The implementation will update and
recompute its best match for the requested storage resolution and format. To then query this state, call
glGetTexLevelParameter(). If the texture cannot be accommodated, texture state is set to 0.
A one-component texture image uses only the red component of the RGBA color extracted from data. A
two-component image uses the R and A values. A three-component image uses the R, G, and B values. A
four-component image uses all of the RGBA components.
NOTES
The glPixelStore() mode affects texture images.
data may be a null pointer. In this case texture memory is allocated to accommodate a texture of width
width, height height, and depth depth. You can then download subtextures to initialize this texture
memory. The image is undefined if the user tries to apply an uninitialized portion of the texture image
to a primitive.
glTexImage3D specifies the three-dimensional texture for the current texture unit, specified with
glActiveTexture().
GL_STENCIL_INDEX may be used for format only if the GL version is 4.4 or higher.
ERRORS
GL_INVALID_ENUM is generated if target is not GL_TEXTURE_3D or GL_PROXY_TEXTURE_3D.
GL_INVALID_ENUM is generated if format is not an accepted format constant. Format constants other than
GL_STENCIL_INDEX and GL_DEPTH_COMPONENT are accepted.
GL_INVALID_ENUM is generated if type is not a type constant.
GL_INVALID_VALUE is generated if level is less than 0.
GL_INVALID_VALUE may be generated if level is greater than log 2 max, where max is the returned value
of GL_MAX_TEXTURE_SIZE.
GL_INVALID_VALUE is generated if internalFormat is not one of the accepted resolution and format symbolic
constants.
GL_INVALID_VALUE is generated if width, height, or depth is less than 0 or greater than
GL_MAX_TEXTURE_SIZE.
GL_INVALID_VALUE is generated if border is not 0.
GL_INVALID_OPERATION is generated if type is one of GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV,
GL_UNSIGNED_SHORT_5_6_5, or GL_UNSIGNED_SHORT_5_6_5_REV and format is not GL_RGB.
GL_INVALID_OPERATION is generated if type is one of GL_UNSIGNED_SHORT_4_4_4_4,
GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1, GL_UNSIGNED_SHORT_1_5_5_5_REV,
GL_UNSIGNED_INT_8_8_8_8, GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, or
GL_UNSIGNED_INT_2_10_10_10_REV and format is neither GL_RGBA nor GL_BGRA.
GL_INVALID_OPERATION is generated if format or internalFormat is GL_DEPTH_COMPONENT,
GL_DEPTH_COMPONENT16, GL_DEPTH_COMPONENT24, or GL_DEPTH_COMPONENT32.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to the GL_PIXEL_UNPACK_BUFFER
target and the buffer object's data store is currently mapped.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to the GL_PIXEL_UNPACK_BUFFER
target and the data would be unpacked from the buffer object such that the memory reads required would
exceed the data store size.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to the GL_PIXEL_UNPACK_BUFFER
target and data is not evenly divisible into the number of bytes needed to store in memory a datum
indicated by type.
