Shading for cel animation based on images is a recent research topic in computer-assisted animation. This paper proposes an image-based shading pipeline to give a 3D ap- pearance to a 2D character by inspecting the hand-drawn image directly. The proposed method estimates normal vec.

Example elements with lengths from len() e = [ [1], [], [3,4,5], 'string', 'x', [[10,11],[12,13,14],[[15,16],[17]]] ]; // length 6 address length element e[0] 1 [1] e[1] 0 [] e[5] 3 [ [10,11], [12,13,14], [[15,16],[17]] ] e[5][1] 3 [ 12, 13, 14 ] e[5][2] 2 [ [15,16], [17] ] e[5][2][0] 2 [ 15, 16 ] e[5][2][0][1] undef 16 e[3] 6 'string' e[3 ][2] 1 'r' s = [2,0,5]; a = 2; s[a] undef 5 e[s[a]] 3 [ [10,11], [12,13,14], [[15,16],[17]] ] vector operators [ ] concat [ ] [ Note: Requires version 2015.03 or later] concat() combines the elements of 2 or more vectors into a single vector. No change in nesting level is made. Vector1 = [1,2,3]; vector2 = [4]; vector3 = [5,6]; new_vector = concat(vector1, vector2, vector3); // [1,2,3,4,5,6] string_vector = concat('abc','def'); // ['abc', 'def'] one_string = str(string_vector[0],string_vector[1]); // 'abcdef' len [ ] len() is a function which returns the length of vectors or strings. Indices of elements are from [0] to [length-1]. Vector Returns the number of elements at this level. Single values, which are not vectors, return undef.

String Returns the number of characters in string. A = [1,2,3]; echo(len(a)); // 3 Matrix [ ] A matrix is a vector of vectors. Example which defines a 2D rotation matrix mr = [ [cos(angle), -sin(angle)], [sin(angle), cos(angle)] ]; Getting input [ ] Now we have variables, it would be nice to be able to get input into them instead of setting the values from code. There are a few functions to read data from DXF files, or you can set a variable with the -D switch on the command line. Getting a point from a drawing Getting a point is useful for reading an origin point in a 2D view in a technical drawing. The function dxf_cross will read the intersection of two lines on a layer you specify and return the intersection point. This means that the point must be given with two lines in the DXF file, and not a point entity.

TotalWidth = dxf_dim ( file = 'drawing.dxf', name = 'TotalWidth', layer = 'SCAD.Origin', origin =[ 0, 0 ], scale = 1 ); For a nice example of both functions, see Example009 and the image on the.

Argument names are optional if given in the order shown here. Cube(size = [x,y,z], center = true/false); cube(size = x, center = true/false); parameters: size single value, cube with all sides this length 3 value array [x,y,z], cube with dimensions x, y and z. Center false (default), 1st (positive) octant, one corner at (0,0,0) true, cube is centered at (0,0,0) default values: cube(); yields: cube(size = [1, 1, 1], center = false); examples: equivalent scripts for this example cube(size = 18); cube(18); cube([18,18,18]);. Cube(18,false); cube([18,18,18],false); cube([18,18,18],center=false); cube(size = [18,18,18], center = false); cube(center = false,size = [18,18,18] ); equivalent scripts for this example cube([18,28,8],true); box=[18,28,8];cube(box,true); sphere [ ] Creates a sphere at the origin of the coordinate system. The r argument name is optional.
