System and apparatus for customizing a computer animation wireframe
View Patent ↗An animation wireframe is modified with three-dimensional (3D) range and color data having a corresponding shape surface. The animation wireframe is vertically scaled based on distances between consecutive features within the 3D range and color data and corresponding distances within the generic animation wireframe. For each animation wireframe point, the location of the animation wireframe point is adjusted to coincide with a point on the shape surface. The shape surface point lies along a scaling line connecting the animation wireframe point, the shape surface point and an origin point. The scaling line is within a horizontal plane.
1. A method for modifying an animation wireframe comprising:
aligning a depth map with a color map;
scaling the animation wireframe in a first direction based on a plurality of distances between feature pairs within a plurality of feature pairs of the depth map;
adjusting in a second direction the location of a first animation wireframe point to correspond to a first point on the shape surface;
appointing a color scheme to the wireframe based on the color scheme of the color map.
2. The method of claim 1 , wherein a primary point is selected from the depth map based on the pell's protrusion with respect to other pell's on the depth map.
3. An apparatus for substantially fitting an animation wireframe to a three-dimensional representation, the apparatus comprising:
a first device for aligning a depth map with a color map, a second device for providing the animation wireframe, a processor receiving a first input from the first device and a second input from the second device, the processor programed to:
select a primary point within the depth map;
draw a first profile line through the primary point parallel to a first access;
select at least one secondary point within the depth map;
estimate a first scaling factor; and
scale the animation wireframe according to the first scaling factor to form a fitted animation wireframe.
4. The method of claim 3 , wherein the primary point within the depth map protrudes the furthest from the depth.
5. The method of claim 3 , wherein the first axis defines a first profile line.
6. The method of claim 3 , wherein the secondary point lies substantially along the profile line.
7. The method of claim 3 , wherein the secondary point can be identified by protrusion from the depth map.
8. The method of claim 3 , wherein the scaling factor is estimated as a function of the distance between the primary point and the secondary point.
9. The method of claim 3 , further comprising scaling the animation wireframe in a second direction.
10. The method of claim 3 , further comprising aligning the depth map with a color map.
11. The method of claim 10 , further comprising applying a color texture from the color map to the animation wireframe.
12. The method of claim 3 , further comprising adding textual shading to the fitted animation wireframe.
