Kwan-Hee Yoo, Dick Puk and Don Brutzman discuss Projective Texture Mapping (PTM) and ProjectorLight proposals for new nodes in X3D 4.0.

• Node design: must be as simple as possible.  Hoping for 2 complementary nodes.
• Easily repeatable by authors without interfering with existing content
• PTM is focused on mapping a texture to geometric surfaces in a scene
• ProjectorLight is focused on a hardware-projector-style light source, perhaps similar to SpotLight

Other participants are most welcome.  Email discussion includes the x3d-public@web3d.org mailing list (subscribe) (archive).
