NAME¶
glTexStorage2DMultisample, glTextureStorage2DMultisample - specify storage for a two-dimensional multisample textureC SPECIFICATION¶
void
glTexStorage2DMultisample(GLenum target,
GLsizei samples,
GLenum internalformat,
GLsizei width, GLsizei height,
GLboolean fixedsamplelocations);
void
glTextureStorage2DMultisample(GLuint texture,
GLsizei samples,
GLenum internalformat,
GLsizei width, GLsizei height,
GLboolean fixedsamplelocations);
PARAMETERS¶
targetSpecifies the target to which the texture object is bound
for glTexStorage2DMultisample. Must be one of
GL_TEXTURE_2D_MULTISAMPLE or
GL_PROXY_TEXTURE_2D_MULTISAMPLE.
texture
Specifies the texture object name for
glTextureStorage2DMultisample. The effective target of texture
must be one of the valid non-proxy target values above.
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 and glTextureStorage2DMultisample specify 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.
