3D graphics based on images and morphing

A method for generating a new view of a three dimensional scene, comprising:

• receiving two or more pictures from two or more view points located on a line along the direction of view;
• projecting the two or more pictures onto a cylinder;
• performing a multi-image morph on the images projected on the cylinder;
• projecting the result of the multi-image morph to generate the new view of the three dimensional scene;
• and
• determining a set of coefficients based on the new point;
• wherein the morphing uses n−1 warping functions, where n is the number of pictures, and wherein the view generating step includes
• generating correspondences between n−1 pairs of pictures,
• generating a weighted average correspondence mapping,
• selecting a picture from the three or more pictures,
• applying a two-image warp of each of the remaining pictures into the selected picture to generate n−1 intermediate pictures,
• generating a blended picture by blending the n−1 intermediate pictures with the selected picture, and
• generating the new view using the weighted average correspondence mapping and the blended picture.

A computer-implemented method for generating a new view of a three dimensional scene, comprising:

• receiving three or more images representing three or more different view points on a first plane, each image taken from a viewing direction perpendicular to the first plane;
• receiving three or more images from three or more different view points on a second plane, each image taken from a viewing direction perpendicular to the second plane, the first plane being parallel to the second plane;
• generating the new view of the three dimensional scene from an arbitrary point in three dimensional space by morphing among the six or more images;and
• determining a set of coefficients based on the new point;
• wherein the morphing uses n−1 warping functions, where n is the number of pictures, and wherein the view generating step includes
• generating correspondences between n−1 pairs of pictures,
• generating a weighted average correspondence mapping,
• selecting a picture from the three or more pictures,
• applying a two-image warp of each of the remaining pictures into the selected picture to generate n−1 intermediate pictures,
• generating a blended picture by blending the n−1 intermediate pictures with the selected picture, and
• generating the new view using the weighted average correspondence mapping and the blended picture.

A method for changing the lighting of a view of a three dimensional scene from a first light source to a second light source, comprising:

• determining a mesh associated with the view of the three dimensional scene from the first light source;
• determining a mesh associated with the view of the three dimensional scene from the second light source;
• determining the amount of light based on the ratio of the areas of pairs of corresponding quadrilaterals in the meshes;
• and
• generating the new view of the three dimensional scene with the determined light.
