Doggy Debris

Goal

To create a game in the first-person point of view.

Description

Doogy debris is an interactive game where the user takes on the perspective of a dog on a surfboard. The user then moves around the ocean using the WASD keys and two finger scrolling to collect water bottles where one bottle equals one point. There will always be 5 bottles present in the water.

Lessons I've Learned

• It is difficult to have an object rotate 360 degrees using arccos.
• Creating realistic water is difficult using only a texture map and lighting
• Textures must be a power of two in size.
• Order of transformation is extremely important.

Key Graphics Technologies

• I created a 7x7 grid on the x & z-axis of the ocean. In each grid I calculated the average y-height of each vertex. So when the dog is on a certain grid in the ocean, the dog's height will change to that average y-height. This is so the dog can be seen at all time and is not under the water obj.
• Collision detection between a point and AABB
• Generating 5 water bottles randomly in the world at all times
• Having the camera follow the dog at all time including when it rotates
• I utilized arccos to find the angle between an initial view vector and the current view vector. I then used that angle to rotate the dog about the y-axis of the camera.

External Resources

• All models were downloaded royalty-free from online sources such as turbosquid.
• This site helped me understand collision detection.

Knowledge Deepened

• Hierarchical modeling
  • Displayed in the sun
  • Having the user follow the dog on a surfboard required this
• Lighting
  • Used a point light to brighten the entire world
  • Used another point light that the sun uses to illuminate the area that the sun is above
• Texture Mapping
  • Mapping images to objects (dog, ocean, skybox)
• Shading
  • The sun, textured objects, and surfboard all have different shading by manipulating diffusion, specular, and ambience values
