💖 NAME 💖

okay so bestie, welcome to GLTEXIMAGE2DMULTISAM(3G) — the manual page for glTexImage2DMultisample. This function’s whole job is to establish the data storage, format, dimensions, and number of samples of a multisample texture's image. slay. 💅

✨ C SPECIFICATION ✨

void glTexImage2DMultisample(GLenum target, GLsizei samples,
                             GLenum internalformat, GLsizei width,
                             GLsizei height,
                             GLboolean fixedsamplelocations);

🎀 PARAMETERS 🎀

  • target — specifies the target of the operation. It 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. It 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 the value of GL_MAX_TEXTURE_SIZE minus one. samples specifies the number of samples in the image and must be in the range zero to the value of GL_MAX_SAMPLES minus one.

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. iykyk 💅

💅 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 is negative or is greater than GL_MAX_TEXTURE_SIZE.
  • GL_INVALID_VALUE is generated if samples is zero. 🫢
  • GL_INVALID_OPERATION is generated if samples is greater than the maximum number of samples supported for this target and internalformat.

okay that’s the whole page — signing off with source/version [FIXME: source] and date 08/09/2021, still the GLTEXIMAGE2DMULTISAM(3G) manual page. mwah 💋✨
