Raster3D

A 3D render engine from scratch, using CUDA/C++.

Perspective Projection, and Rotation, demonstrating coordinate transforms.	Flat Shading on Surfaces of Complex Polygons

Getting Started

Ensure you meet the requirements before attempting to build and run.

Cloning the repository:

git clone https://github.com/Sundance636/Raster3D.git

Prerequisites

• CUDA-Compatible GPU (Nvidia to play it safe)
• CUDA-toolkit
• SDL2 libs

Linux

Using your package manager of choice install the required packages

Arch Linux

sudo pacman -S cuda && sudo pacman -S sdl2

Once the packages are installed, go to the root of the repo and run the makefile, running make will just build the project while make profile will build and run with nvprof to profile the runtime:

make profile 

You can manually Run the executable with:

./Engine 

Windows

(Coming soon, probably)

Usage

When the program is started you will be presented to a scene where the camera is centered at the origin, you may move around to observe, and the terminal continuously will display some information about the current scene.

Controls
Arrow Keys	Pan the camera in the respective direction
W	Rotate camera up
A	Rotate camera left
S	Rotate camera down
D	Rotate camera right
E	Move camera forward
Q	Move camera backwards
(More options and user controls coming soon)
