glTexStorage3DMultisample — specify storage for a two-dimensional multisample array texture
void glTexStorage3DMultisample( | GLenum | target, |
GLsizei | samples, | |
GLenum | internalformat, | |
GLsizei | width, | |
GLsizei | height, | |
GLsizei | depth, | |
GLboolean | fixedsamplelocations) ; |
target
Specify the target of the operation. target
must be
GL_TEXTURE_2D_MULTISAMPLE_ARRAY
or GL_PROXY_TEXTURE_2D_MULTISAMPLE_MULTISAMPLE
.
samples
Specify the number of samples in the texture.
internalformat
Specifies the sized internal format to be used to store texture image data.
width
Specifies the width of the texture, in texels.
height
Specifies the height of the texture, in texels.
depth
Specifies the depth of the texture, in layers.
fixedsamplelocations
Specifies whether the image will use identical sample locations and the same number of samples for all texels in the image, and the sample locations will not depend on the internal format or size of the image.
glTexStorage3DMultisample
specifies the storage requirements for
a two-dimensional multisample array texture. Once a texture is specified with this
command, its format and dimensions become immutable unless it is a proxy
texture. The contents of the image may still be modified, however, its storage requirements
may not change. Such a texture is referred to as an immutable-format
texture.
samples
specifies the number of samples to be used for the texture
and must be greater than zero and less than or equal to the value of GL_MAX_SAMPLES
.
internalformat
must be a color-renderable, depth-renderable, or stencil-renderable format.
width
and height
specify the width and height,
respectively, of the texture and depth
specifies the depth (or the number of layers)
of the texture. If fixedsamplelocations
is GL_TRUE
,
the image will use identical sample locations and the same number of samples for all texels in the image,
and the sample locations will not depend on the internal format or size of the image.
