Embodiment Construction
[0020] Such as figure 1 As shown, the implementation process of the present invention includes two parts: a preprocessing stage and a runtime stage.
[0021] The first stage: the preprocessing part. It includes five steps of reading sampling points, template generation, space division, solving k-nearest neighbors, and calculating curvature.
[0022] Step 1: Read the sampling point.
[0023] Read and store the space coordinates, normal vector, radius, color and other information of the sampling point. The position and orientation of this point on the model surface can be known through the space coordinates and normal vectors of the sampling point in the object coordinate system. The radius of the sampling point can ensure that the splat (the projection of the surface element on the two-dimensional screen) covers each other without holes, and the color information can be changed. Well presented model details.
[0024] Figure 6 The space coordinates, normal vector, radius a...
