于是乎，emmm，貌似还完成了上面提到的梦想，上表面”高光”以及底面的透光，不仅如此，而且镂空内表面还有透光，还映在了大地上，强无敌嘞~
上述场景代码
intersect* light() { texture * perlintex = new noise_texture(6.3); material* redlight = new areaLight(new constant_texture(rtvec(0.98, 0.1, 0.08))); material* bluelight = new areaLight(new constant_texture(rtvec(0.05, 0.05, 1.))); intersect**list = new intersect*[7]; list[0] = new sphere(rtvec(-2, 3, -3), 1.5, redlight); list[1] = new sphere(rtvec(-2.2, 3.2, 2.8), 1.5, bluelight); list[2] = new sphere(rtvec(0, 0, 2.2), 1, new metal(new constant_texture(rtvec(1, 1, 1)))); list[3] = new sphere(rtvec(), 1, new lambertian(new constant_texture(rtvec(1, 1, 1)))); list[4] = new sphere(rtvec(0, 0, -2), 1, new dielectric(1.5)); list[5] = new sphere(rtvec(0, 0, -2), -0.18, new dielectric(1.5)); list[6] = new sphere(rtvec(0, -1000, 0), 999, new dielectric(1.5)); return new intersections(list, 7); }
