glTexStorage2DMultisample
specify storage for a two-dimensional multisample texture
C Specification
void glTexStorage2DMultisample
GLenum target
GLsizei samples
GLenum internalformat
GLsizei width
GLsizei height
GLboolean fixedsamplelocations
Parameters
target
Specify the target of the operation. target must be
GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_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.
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.
Description
glTexStorage2DMultisample specifies the storage requirements for
a two-dimensional multisample 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. 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.
Errors
GL_INVALID_ENUM is generated if internalformat is not a
valid color-renderable, depth-renderable or stencil-renderable format.
GL_INVALID_ENUM is generated if target is not
one of the accepted target enumerants.
GL_INVALID_VALUE is generated if width or height
are less than 1 or greater than the value of GL_MAX_TEXTURE_SIZE.
GL_INVALID_VALUE is generated if samples is greater than the
value of GL_MAX_SAMPLES.
GL_INVALID_OPERATION is generated if the value of GL_TEXTURE_IMMUTABLE_FORMAT
for the texture bound to target is not GL_FALSE.
