PANORAMA VIDEO CONVERT TO 6 FACE SOFTWARE
PANORAMA VIDEO CONVERT TO 6 FACE CODE

The the direction vector is given as follows. In particular, if (i,j) is the pixel index of the panoramic normalised to (-1,+1) The vertical axis of the cylinder by a tan relationship. The vertical axis of the panoramic image maps onto The horizontal axis maps linearly onto the angleĪbout the cylinder. The correct location on the appropriate cubic face is The mapping for each pixel in the destination cylindrical panoramic from Spherical (equirectangular) projections, see later. Vertical field of view is required then perhaps one should be using With the top of the cylindrical panoramic.Īs the vertical field of view approaches 180 degree the representationĪs a cylindrical projection become increasingly inefficient. Note that in this special case the top of the face should coincide Note the orientation convention for the cube faces. T_starmap.tga, b_starmap.tga, d_starmap.tga. L_starmap.tga, r_starmap.tga, f_starmap.tga, So for example the following cubic maps would be specified as %c_starmap.tga, The file mask needs to contain '%c' which specifies the view. The names of the cubic maps are assumed to contain the letters s split cylinder into 4 pieces, default = off c enable top and bottom cap texture generation, default = off w n sets the output image width, default = 3 * cube image width a n sets antialiasing level, default = 2

The software was scripted to create the 6 cubic images and thisįilemask can contain %c which will substituted with each of įor example: 'blah_%c.tga' or '%c_something.tga' Images from rendering software that didn't explicitly support panoramicĬreation. The motivation for this was the creation of cylindrical panoramic The following discusses the transformation of a cubic environment map (90ĭegree perspective projections onto the face of a cube) into a cylindrical For more information please contact the author.Ĭonverting from cubemaps to cylindrical projectionsĬonverting from cylindrical projections to cube mapsĬonverting to and from 6 cubic environment maps and a spherical projectionĮxtracting a perspective projection from cubemaps

It includes a demo application and an invitation to convert an image of your choice to verify the code does what you seek. The source code implementing the projections below is only available on request for a small fee. See also: Converting cubemaps to fisheye. Converting to/from cubemaps Converting to/from cubemaps
