Overview

This package is a set of utilities for Sp3dObj (simple_3d package). It currently includes utilities that make it easy to generate geometry and a simple set of materials.

simple_3d package

Usage

Create Geometry

import 'package:simple_3d/simple_3d.dart';
import 'package:util_simple_3d/util_simple_3d.dart';

Sp3dObj obj = UtilSp3dGeometry.capsule(50, 250);

Use Default Material

import 'package:simple_3d/simple_3d.dart';
import 'package:util_simple_3d/util_simple_3d.dart';

Sp3dObj obj = UtilSp3dGeometry.cube(200,200,200,4,4,4);
obj.materials.add(FSp3dMaterial.green.deepCopy());
obj.fragments[0].faces[0].materialIndex=1;

Geometry type

Tile

Sp3dObj obj = UtilSp3dGeometry.tile(200, 200, 4, 4);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);

Tile

Cube

Sp3dObj obj = UtilSp3dGeometry.cube(200,200,200,4,4,4);
obj.materials.add(FSp3dMaterial.green.deepCopy());
obj.fragments[0].faces[0].materialIndex=1;
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 0, 255);
obj.rotate(Sp3dV3D(1,1,0).nor(), 30*3.14/180);

Cube

Circle

Sp3dObj obj = UtilSp3dGeometry.circle(100, fragments: 20);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);

Circle

Cone

Sp3dObj obj = UtilSp3dGeometry.cone(100, 200);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);
obj.rotate(Sp3dV3D(1, 0, 0), -100*3.14/180);
obj.move(Sp3dV3D(0, -100, 0));

Cone

Pillar

Sp3dObj obj = UtilSp3dGeometry.pillar(50, 50, 200);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);
obj.rotate(Sp3dV3D(1, 0, 0), -120*3.14/180);
obj.move(Sp3dV3D(0, -100, 0));

Pillar

Sphere

Sp3dObj obj = UtilSp3dGeometry.sphere(100);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);

Sphere

Capsule

Sp3dObj obj = UtilSp3dGeometry.capsule(50,200);
obj.materials[0] = FSp3dMaterial.grey.deepCopy()..strokeColor=Color.fromARGB(255, 0, 255, 0);
obj.move(Sp3dV3D(0, 100, 0));

Capsule

Wire frame

Sp3dObj obj = UtilSp3dGeometry.cube(200,200,200,4,4,4);
obj.materials.add(FSp3dMaterial.greenWire.deepCopy());
obj.fragments[0].faces[0].materialIndex = 1;
obj.materials[0] = FSp3dMaterial.blueWire.deepCopy();
obj.rotate(Sp3dV3D(-0.2,0.5,0).nor(), 15*3.14/180);

Wire frame

Common parts

Coordinate arrows and mesh creation

List<Sp3dObj> objs = UtilSp3dCommonParts.coordinateArrows(255);
objs.addAll(UtilSp3dCommonParts.worldMeshes(255));

Coordinate arrows and world meshes
