3pp

repodemo

3pp - 3d perspective projection, is an example demo of rendering 3d models onto a 2d plane using perspective projection. The project is only for educational purposes only and is not meant for anything serious.

Algorithm

It is derived from this formula:

Given a point (x, y, z) in 3d space, the 2d point on the screen is given by:

x' = xf / z
y' = yf / z

where f is the distance between the image plane and the center of projection.

Features

Run

You can run the demo by cloning the repo and install serve to run it locally.

npm install -g serve
git clone https://github.com/nibtr/3pp
cd 3pp
serve .

or visit the demo.

References

The demo is mostly referenced from this video by Tsoding. He explains the algorithm pretty clearly.
