naiverend
A lightweight OpenGL renderer with naive hardcoded shader program
Loosely based on OGLdev-tutorials with marching cubes implementation built upon Paul Bourke's paper.
Cmake build should work^tm on windows (vs2015) and osx (clang) if GLFW3 is installed. git submodule init and git submodule update are needed to pull imgui.
Model to be loaded is currently hardcoded in scene.cpp as is it's scale and orientation. Interaction includes an arcball-implementation with mouse wheel controlling the distance plus arrows and shift - up/down controlling the model's position.
Layer file parser is a marching cubes implementation which takes numbered (*.1 - *.n) layer files with a header in the same folder. Header is constructed as follows:
name MRbrain
filename MRbrain.
threshold 1400
resX 256
resY 256
layers 109
aspX 1
aspY 1
aspZ 2
^^This is used to parse MRbrain from https://graphics.stanford.edu/data/voldata/
