Volume-Renderer

A basic Volume Renderer mainly for Medical Images like CT-Scans and MRI Images. Uses Dear ImGui for GUI and stb_image_write for saving images. The Volume Renderer is based on Direct Volume Ray Casting and uses GPU based raymarching. Currently no transfer functions are implemented however simple min/max values can be set to view a certain range of the values. Currently only ".RAW" or ".PVM" files are read.

Some sites that provide free public volume datasets are listed below

TODO:

• Add transfer functions
• Add support for DICOM Images
• Add support for reading large files (GBs) and sending data over to GPU
