3-D Computer Graphics Library

cg3d.js (c) 2017 Boris Buimov

version 1.1.4

This library contains three classes to work with three-dimensional elements of computer graphics - objects, transformations matrices and a scene (With a JSDoc documentation).

API

cg3d.Object3d(vertices, edges, settings) - Creates an object.

cg3d.Object3d.applyTransformation(tMx) - Applies a transformation to the object.

cg3d.Object3d.getCaptions() - Returns captions of the verteces and their visual settings.

cg3d.Object3d.getCopy() - Copies the object.

cg3d.Object3d.getElems() - Gets elements of the object matrix.

cg3d.Object3d.getPoints() - Returns coordinates of the object verteces and their visual settings.

cg3d.Object3d.getSegments() - Returns coordinates of the object edges and their visual settings.

cg3d.Object3d.trace() - Displays the array elements into columns like in matrixes.

cg3d.Transform3d(els) - Creates a matrix of combined transformations.

cg3d.Transform3d.getElems() - Gets elements of the transformation Matrix.

cg3d.Transform3d.getMatrix() - Returns a copy of the transformation Matrix.

cg3d.Transform3d.move(axis, v) - Multiplies the matrix of combined transformations by translation matrix.

cg3d.Transform3d.perspective(axis, v) - Multiplies the matrix of combined transformations by perspective matrix.

cg3d.Transform3d.rotate(axis, angle) - Multiplies the matrix of combined transformations by rotation matrix.

cg3d.Transform3d.rotateFree(vector, angle) - Multiplies the matrix of combined transformations by arbitary rotation matrix.

cg3d.Transform3d.scale(axis, v) - Multiplies the matrix of combined transformations by scaling matrix.

cg3d.Transform3d.trace() - Displays the array elements into columns like in matrixes.

cg3d.Scene3d(ctx, center, scale) - Creates a scene with three-dimensional objects.

cg3d.Scene3d.addObject(obj) - Adds an object to the object array of the scene.

cg3d.Scene3d.clearObjects(idx) - Removes one or more objects from the object array of the scene.

cg3d.Scene3d.draw() - Displays the objects of the scene.

cg3d.Scene3d.drawCaptions(captions) - Displays the captions of the verteces.

cg3d.Scene3d.drawPoints(points) - Displays the object verteces.

cg3d.Scene3d.drawSegments(segments) - Displays the object edges.

setSpace() - Creates a transformation matrix to convert object coordinates into the screen coordinates.

cg3d.Scene3d.setView(vector, isPerspective) - Creates a transformation matrix to set a viewport up.
