Software Rasterizer - Forward Rendering Pipeline Implementation

This is a basic software rasterizer, implemented Modeling Transformation, Viewing Transformation, and Rasterization stages of the Forward Rendering Pipeline in C++.

Some of the properties of the Software Rasterizer as follows:

• Supported two types of projection transformations: orthographic projection and perspective projection.
• Used the midpoint algorithm to draw triangle edges and use the barycentric coordinates based algorithm to rasterize triangle faces.
• Liang-Barsky Clipping algorithm is used
• In both wireframe and solid modes, triangles whose backface is facing the viewer will be culled.
• Having strong OOP features
• Parsing XML scene files and rendering images in PPM format

QuickStart

Download the repository

git clone https://github.com/ramazantokay/SoftwareRasterize.git

and run the following command on the terminal

make all

then, you can use the RayTracer with this command

./rasterize <sample_scenes/scene_file.xml>

It will render the scene and save it in its current directory with ppm format.
