OpenGL/GLSL Volume Rendering

Ray-casting volume rendering experiments in OpenGL/GLSL for Windows.

Dependencies

Project uses conan to install:

• GLM: https://github.com/g-truc/glm
• GLAD: https://github.com/Dav1dde/glad
• GoogleTest: https://github.com/google/googletest

Build

To test and build, run conan and cmake:

mkdir build
cd build
conan install .. -s build_type=Release -s compiler.runtime=MD
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release
ctest -C Release  -VV
cmake --install .

The executable with shaders can be found in build/product.

Usage

Hotkeys:

• Esc: close application
• Space Bar: pause/start animation
• Backspace or D: remove object
• A: add object
• N: toggle procedural noise deformation on/off
• 0 to 9: different rendering/shading modes

The rendering modes are:

• 1: object normals
• 2: Lambertian reflectance
• 3: Phong reflection
• 4: Fresnel effect
• 5: Hard shadows
• 6: Volumetric light effect
• 7: object colors
• 8: reserved
• 9: "blood" effect combining the above effects
• 0: default rendering combining the above effects
