naivert: An Implementation For Ray Tracing Algorithm¶
About naivert¶
naivert is an implementation of ray tracing algorithm using Phong illumination model.
For geometry calculation, naivert uses the library of Geometry3D.
You may refer to the examples and documentation of Geometry3D to get to know how to use naivert.
Core Features¶
Simple Object like Cubic, Sphere, Cylinder, Cone, Rectangle, Parallepiped, Parallogram and Circle.
Point light sources and ambient light sources.
Basic materials.
Ray tracing algorithm rendering.
Phong illumination model.
Resources¶
Examples¶
Here are some examples. This might be very slow, you should change the resolution of the image to reduce the time cost.
Example 1¶
Simply run the code below after installation:
>>> import naivert
>>> from Geometry3D import *
>>> from math import sqrt
>>> main_scene = naivert.Scene()
>>> main_camera = naivert.Camera(Point(400,-300,400),Point(385,-285,385),10 * Vector(-1 /sqrt(6),1/sqrt(6),>>> 2/sqrt(6)),10*Vector(1/sqrt(2),1/sqrt(2),0),'main_camera.png',resolution=(600,600))
>>> point_light = naivert.PointLight(Point(50,100,200),[5.0,5.0,5.0])
>>> point_light2 = naivert.PointLight(Point(200,50,200),[4.0,4.0,4.0])
