archit120/3d-graph

3D graph rendered that allows fps like movement

Hey there, I'm Archit 👋

I'm an undergraduate at Indian Institute of Technology Kharagpur working in the fields of Robotics, Computer Vision and Reinforcement Learning. In the past, and often when I find the time, I also work on software and backend development.

Present

Currently I'm working on bridging OpenCV and Julia. This is my return to software development after a long break and I'm seriosuly enjoying the work aswell as community involvement in open source work.

Apart from that I'm also working on some projects related to Aerial Robots and RL. Very excited about the things to come.

You can find more about me at archit.me but I'd rather prefer you just send me an email and I'd be happy to talk. ✌️ Peace out!

3d-graph's Issues

Create a function to load bmp and jpg images for textures

Part of the texture package

Texture support

Add support for rendering basic jpeg or bmp texture in triangle and render

Implement normal ratio shading for triangles

Refer https://www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-shading/shading-normals

Add support for loading 3d models in triangles form

Improve Rendering Speed

Most of the calculations for the rendering can be represented as operations on matrices. These can be vectorized to increase speed dramatically.

Linux platform support

Add Linux support starting from Ubuntu. Major changes to main and render

Update only when camera paramters changed

Currently the code draws again after every loop. Redraw only if camera parameters are changed by the control loop

No Build Instructions on Readme

No method of building, or proper details specified in Readme

Document different classes

Code is easy to understand but documentation always helps.

Add triangle support in render.h

Having support for triangles will allow us to render surfaces more easily. This should be a simple function taking in 3 screen coordinates (x,y) and color and filling the space with the color.

Compiling errors when using make

Hi dear experts
I'm building 3D-Graph these days and following the steps here:
$mkdir build
$cd build
$cmake ..
$make
but the errors occurred here:

thank you

Seperate out the control loop

Currently the control loop is in the min function cluttering it. Seperate it to a separate file

Add gradient support in render.h

Add gradient color support instead of just solid colors.
