💖 NAME 💖

coin_projectors — it's the Projector Classes page, bestie 💅 (it lives in section 3 of the Coin manual, iykyk)

Okay so real talk: the projector classes are the little glow-up agents that convert between screenspace (2D) locations and locations in worldspace (3D). That's literally the whole job description. 🦋

✨ SYNOPSIS ✨

🎀 Classes 🎀

  • SbCylinderPlaneProjector — projects 2D points onto a half-cylinder and a plane. Two surfaces, one projector, no drama.
  • SbCylinderProjector — the abstract base class for mapping to cylindrical surfaces. It's the blueprint, not the vibe itself.
  • SbCylinderSectionProjector — projects 2D points onto a sliced cylinder. Sliced, like a lil cucumber 🥒
  • SbCylinderSheetProjector — projects 2D points to 3D points on a sheet covering a cylindrical shape.
  • SbLineProjector — projects 2D points to 3D points along a line. Straight up. Literally straight.
  • SbPlaneProjector — projects 2D points to 3D points in a plane. Flat-earther behaviour, but make it geometry.
  • SbProjector — the abstract base projector class, aka the mother of them all 👑
  • SbSpherePlaneProjector — projects 2D points onto a half-sphere and a plane. Best of both worlds fr fr.
  • SbSphereProjector — the abstract base class for mapping to spherical surfaces 🌈
  • SbSphereSectionProjector — projects 2D points onto a sliced sphere. Cutie with a cross-section.
  • SbSphereSheetProjector — projects 2D points to 3D points on a sheet covering a spherical shape. Wrapping the sphere like it's a lil gift 🎁

🌸 Detailed Description 🌸

The projector classes are used to convert between screenspace (2D) locations and locations in worldspace (3D). That's it, that's the mission statement.

They are mostly used in relation to user interaction with the mouse in the viewport. So when your cursor does a thing and the 3D scene somehow gets it — yeah, that's these. Mouse girlies, this one's for you 🖱️💖
