3D-grafhics

This is my project in Introduction to Software Engineering course.
I did the project with @Ruli Yakovson.

Description

The software has the ability to model

• basic geometrical shapes such:

  • points
  • vectors

• geometric shapes in 3D:

  • square
  • circle
  • triangle
  • ball
  • cylinder

• sources of lighting such:

  • point lights
  • spote
  • direction (Model for ultra-powerful lighting types).

The software describes a scene composed of many geometric shapes, and many lights,
then the software simulates taking a picture of the scene and creates a picture of it in a jpg file.
The picture will resemble the reality considering color, light, shade, transparency and reflection.

How It Works

step 1:
Each geometry implements a function that receives a ray (starting point + vector) and returns the point in the space in which the ray strikes, so when we want to take a picture, for each pixel in the image we want to create we sends a ray from the same pixel and then check if the ray striks some geometries, if there is more than one we find the nearest intersection point to the camera.

step 2:
culculate the color and light of the intersection point.

step 3:
culculate the shadow of the point.

step 4:
culculate the transparency and reflection of the intersection point.

Performence

the app Implement the 3D-DDA algorithm to save performence.
