Kjøttbasaren

A simple 3D scene of Bergen, Norway and the Kjøttbasaren with manual and automatic navigation and various shading effects. Starting takes some time due to the large terrain file.

Developed by Sören Henning and Zach Litzinger

Features

• 3D Terrain of the city Bergen
• Model of the Kjøttbasaren building
• Manual navigaton in x, y and z direction
• Automatic navigation using composite Bezier curves
• Horizontal and vertical rotation
• Directional sunlight (on/off switch, night mode)
• Headlight on top of the camera, point light with decreasing intensity (on/off switch)
• Perspective and orthographic projection
• Per fragment shading with various effects (fog, black and white, linocut (similiar to toon), noise, vignette, normal highlighting, terrain colors per height)
• Adjustable mix of material properties and textures
• Objects imported as .obj files
• Textures and material properties imported from .mtl files
• Skybox included

Navigation

Mouse

Dragging with left mouse button: Rotating

Dragging with middle mouse button: Zooming in and out

Dragging with right mouse button: Move forward, right, left and backwards

Keyboard

w, s: Move forward and backwards (in viewing direction)

a, d: Move left and right

c, space: Move up and down

m, n: Decrease or increase field of view

b: Toggle projection between orthographic and perspective

r: Reset camera

v: Toggle automatic camera movement

i: Print info about current camera status

k: Change texture intensity (0% - 100%)

y: Toggle sunlight (night mode)

x :Toggle headlight

1: Switch to realistic shading (per fragment illumination)

2: Switch to foggy shading (per fragment illumination)

3: Switch to black and white shading (per fragment illumination)

4: Switch to linocut shading (per fragment illumination)

5: Switch to noise shading (per fragment illumination)

6: Switch to vignette shading (per fragment illumination)

7: Switch to normal highlight shading (face normals are mapped to colors, useful for debugging) (per fragment illumination)

8: Switch to terrain height colors shading (per fragment illumination)

l: Reload shaders

p: Set drawing to wireframes

o: Set drawing to solid faces

q: Quit

Building it

• Visual Studio 2017 solution included
• Important: Project has to be compiled for x64 to load all objects properly
• FreeGLUT and Glew for Windows included
• Terrain Importer (transform to .obj file) located in terrain-importer/main.kt

kjottbasaren's Issues

sophisticated lights

decreasing intensity with distance

Implement Headlight

orthographic projection

Normals are not passed to shader

Implement Rotation

Have implemented translation and zooming

Implement 1 directional light

Adjust Light Colors and Intensities

E.g., headlight is too bright

Per fragment illumination

Implement our own shading methods

Model Camera as own class

Convert the Camera struct to a class containing methods for navigation, getting the transformation matrix and printing the current state.

Ad possibility to switch between shaders

Render the model

We have loaded the wireframe, but have not rendered it yet

implement perspective camera
