projection

Assuming I have infinite vertices to represent the sphere, if I project the sphere from any position/scale in 3D to 2D, will it be a circle?

I know it will not be a circle on the screen, because of scaling and different resolutions. But do field of view and aspect ratio effect the results?

Edit: Sorry yes, I am talking about perspective projection. Seems the answer is no then, perspective will distort the sphere. Thanks!

Hi. I've taken a large image and divided it in to square tiles (256x256). It is made for google maps also, so the whole image is divided into z_x_y.png (Depending on zoom level). z=0 = 1x1 tile z=1 = 2x2 tilesthe z=2 = 4x4 tiles My imageMap is "flat" and is not based on a sphere like the worldmap… >>> More
