Then you … WebMar 24, 2016 · The easiest surface is probably the top part of the cylinder, lying above the sphere; the normal to the cylinder is easy. But you can choose any surface, such as the portion of the sphere enclosed by your curve. That normal is also easy to write down, but it may be hard to calculate with. – symplectomorphic Mar 23, 2016 at 22:00
WebApr 5, 2016 · I've written this code for my game and what I want is to flip the normals on a texture in unity. I have a model and a texture and wish for the texture to be inside the sphere model and not on the outside. I want to create a 360 panoramic effect by moving the camera around the images inside the sphere on top of the flipped texture. WebMay 9, 2024 · Normal Transfer.
