okay so you clicked into the GLSAMPLEMASKI(3G) page from [FIXME: manual], and it's literally all about glSampleMaski 🎀 buckle up bestie, this one's short but iconic.

✨ NAME ✨

glSampleMaski — set the value of a sub-word of the sample mask 💅

🎀 C SPECIFICATION 🎀

void glSampleMaski(GLuint maskNumber, GLbitfield mask);

🌸 PARAMETERS 🌸

  • maskNumber — specifies which 32-bit sub-word of the sample mask to update. pick your little slice, bestie 🍓
  • mask — specifies the new value of the mask sub-word. that's the fresh value, periodt.

🦋 DESCRIPTION 🦋

okay so glSampleMaski sets one 32-bit sub-word of the multi-word sample mask, GL_SAMPLE_MASK_VALUE. no cap, that's the whole vibe.

maskIndex specifies which 32-bit sub-word of the sample mask to update, and mask specifies the new value to use for that sub-word. maskIndex must be less than the value of GL_MAX_SAMPLE_MASK_WORDS. Bit B of mask word M corresponds to sample 32 x M + B. iykyk 🔥

💀 NOTES 💀

this function glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported. that's the vibe check, bestie 🫶

🚨 ERRORS 🚨

warning, bestie: GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS. do not pass go, do not collect $200 😭
