Sorry, my mistake. No FOV in Ortho2D projection, obviously! I tried that setRange(id, 0.5, 2) and it did not work, no tile is ever rendered..
Notice that my tiles are added to the scene graph as geodes, with size = tileSize / scale, hence, a tile is always 256 pixels, but the geode size is set to world coordinates as the size that tile occupies in the whole image frame coordinates. 2016-09-14 10:41 GMT+01:00 Valerian Merkling <[email protected]>: > > > I am also using an Ortho2D projection (field of view 30 degrees) > > > There is no such things as field of view for Ortho projection. > > > > > > > So, Let me draw a specific scenario: an image pyramid, starting at scale > 0.125, going all the way up to 0.25, 0.5, 1.0.I am also using an Ortho2D > projection (field of view 30 degrees).
