// // time: Fri Jan 16 09:20:58 1998 // // version: 3.1.1 (format), 3.1.4 (DX) // // // MODULE main // CATEGORY Macros // // comment: This program shows how you can use Compute to make a parametric surface from the 2D positions of a field. The Mark module is used to mark the "positions" component as "data" so that Compute can operate on the positions. The Compute module produces a 3-vector of positions. After the 2D positions are mapped to 3D, the positions are returned to the "positions" component using the Unmark module. Normals are added for shading, and the result is displayed. // workspace: width = 288, height = 733 // layout: snap = 0, width = 50, height = 50, align = CC // macro main( ) -> ( ) { // // node Construct[1]: x = 143, y = 19, inputs = 4, label = Make a 40x40 grid and fill it with INTEGERS // input[1]: defaulting = 0, visible = 1, type = 16777224, value = {[-1, -1 0]} // input[2]: defaulting = 0, visible = 1, type = 16777224, value = {[0.05, 0.05 0]} // input[3]: defaulting = 0, visible = 1, type = 8, value = [40, 40 1] // input[4]: defaulting = 0, visible = 1, type = 16777245, value = {1 .. 1600 : 1} // main_Construct_1_out_1 = Construct( main_Construct_1_in_1, main_Construct_1_in_2, main_Construct_1_in_3, main_Construct_1_in_4 ) [instance: 1, cache: 1];
