GLBLENDCOLOR(3G)

✨ NAME ✨

glBlendColor from the 3G manual — set the blend color. That's it, bestie, that's the name section, and it's literally that simple. 💖

💅 C SPECIFICATION 💅

okay so the C signature is giving:

void glBlendColor( GLclampf red,
                   GLclampf green,
                   GLclampf blue,
                   GLclampf alpha )

🎀 PARAMETERS 🎀

• red, green, blue, alpha — these specify the components of GL_BLEND_COLOR. 🎨

🦋 DESCRIPTION 🦋

The GL_BLEND_COLOR may be used to calculate the source and destination blending factors. The color components are clamped to the range [0, 1] before being stored — so they get squished into that range first, no cap. See glBlendFunc for a complete description of the blending operations. Initially the GL_BLEND_COLOR is set to (0, 0, 0, 0). ✨

🌸 NOTES 🌸

glBlendColor is part of the GL_ARB_imaging subset. It's present only if GL_ARB_imaging is returned when glGetString is called with GL_EXTENSIONS as its argument. So if that return doesn't happen, this function is not in the group chat, bestie. 🫶

💀 ERRORS 💀

GL_INVALID_OPERATION is generated if glBlendColor is executed between the execution of glBegin and the corresponding execution of glEnd. That's the forbidden zone, periodt. 🚨

🔥 ASSOCIATED GETS 🔥

• glGet with an argument of GL_BLEND_COLOR — that's the associated get, icon behavior. 🔍

okay bestie, that's the whole page — signing off from the GLBLENDCOLOR(3G) footer 💅 That's the source/version stamp on this page, and there's no date listed, so I'm not making one up. bye 😭🫶✨
