NTHU Graphics Programming and Applications

A collection of real-time rendering assignments and a final project developed in C++/OpenGL. The work moves from hierarchical character animation to screen-space post-processing, GPU-driven scene rendering, and a multi-effect deferred-rendering showcase.

Results

Projects

HW1 — Hierarchical robot

An articulated robot assembled with hierarchical transformations.

• Parent/child transformation stack for connected body parts.
• Mouse-driven camera rotation and zoom.
• WASD movement and a right-click menu for animation playback/pause.
• Built with Visual Studio 2019, OpenGL, FreeGLUT, GLEW, and GLM.

Report and screenshots

HW2 — Image-space effects

An interactive scene demonstrating fragment-shader and post-processing effects:

• normal textured rendering;
• image abstraction and watercolor stylization;
• magnifier and movable comparison bar;
• bloom, pixelization, and sine-wave distortion.

Use WASD and Z/X to move, drag the mouse to look around, and right-click to choose an effect.

HW3 — GPU-driven grassland

A large-scene rendering exercise using compute and graphics shaders.

• Grass and bush rendering with dedicated shader programs.
• Compute-shader reset/culling stages.
• View-frustum representation, spatial sampling, and trajectory support.
• Player-view navigation with W/S and turning with A/D.

Final — Rendering showcase

The final directory contains indoor and outdoor renderer applications. Together they demonstrate a broader real-time pipeline:

• deferred shading and G-buffer construction;
• shadow mapping, SSAO, FXAA, bloom, NPR, and volumetric lighting;
• model loading and camera control;
• an outdoor terrain scene with instanced vegetation, buildings, an airplane, and a magic-stone effect.

The final project was collaborative; the two scene directories preserve the renderer code and assets used by the team.

Build and run

The checked-in projects target Windows and Visual Studio. Dependencies such as GLFW/GLAD, GLM, Assimp, ImGui, and model-loading helpers are bundled with the corresponding frameworks.

1. Open the .sln file for the desired assignment or final scene.
2. Retarget the Windows SDK if Visual Studio requests it.
3. Build the main application project.
4. Run with the working directory set to the folder containing that project's shaders/assets so relative paths resolve.

Key solutions include:

• HW1/110062222_AS1/110062222_Robot/110062222_Robot.sln
• HW2/110062222_AS2/AS2_Framework/VC14/AS2_Framework.sln
• HW3/GPA_Assignment3_Framework/Rendering_Framework.sln
• Final/Indoor/Rendering_Framework.sln
• Final/Outdoor/Rendering_Framework.sln
