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. <xi:include></xi:include> 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. SEE ALSO

glTexImage2DMultisample - establish the data storage, format, dimensions, and number of samples of a multisample texture's image C SPECIFICATION
void glTexImage2DMultisample(GLenum target, GLsizei samples, GLint internalformat, GLsizei width, GLsizei height, GLboolean fixedsamplelocations); PARAMETERS
target Specifies the target of the operation. target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE. samples The number of samples in the multisample texture's image. internalformat The internal format to be used to store the multisample texture's image. internalformat must specify a color-renderable, depth-renderable, or stencil-renderable format. width The width of the multisample texture's image, in texels. height The height of the multisample texture's image, 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
glTexImage2DMultisample establishes the data storage, format, dimensions and number of samples of a multisample texture's image. target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE. width and height are the dimensions in texels of the texture, and must be in the range zero to GL_MAX_TEXTURE_SIZE - 1. samples specifies the number of samples in the image and must be in the range zero to GL_MAX_SAMPLES - 1. internalformat must be a color-renderable, depth-renderable, or stencil-renderable format. 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. When a multisample texture is accessed in a shader, the access takes one vector of integers describing which texel to fetch and an integer corresponding to the sample numbers describing which sample within the texel to fetch. No standard sampling instructions are allowed on the multisample texture targets. NOTES
glTexImage2DMultisample is available only if the GL version is 3.2 or greater. ERRORS
GL_INVALID_OPERATION is generated if internalformat is a depth- or stencil-renderable format and samples is greater than the value of GL_MAX_DEPTH_TEXTURE_SAMPLES. GL_INVALID_OPERATION is generated if internalformat is a color-renderable format and samples is greater than the value of GL_MAX_COLOR_TEXTURE_SAMPLES. GL_INVALID_OPERATION is generated if internalformat is a signed or unsigned integer format and samples is greater than the value of GL_MAX_INTEGER_SAMPLES. GL_INVALID_VALUE is generated if either width or height negative or is greater than GL_MAX_TEXTURE_SIZE. GL_INVALID_VALUE is generated if samples is greater than GL_MAX_SAMPLES. SEE ALSO
