My Project Idea

Basketball - Using Lab 9 My project idea is to recreate a similar image to the picture below. I will have a basketball appear in the same position on the screen on a shiny basketball court. I will set up a key press for the ball to be bounced in a GIF animation. Some computer graphics elements for my project: Ray Tracing Multiple lighting Ambient lighting/Diffuse lighting Specular highlight Texture mapping for floor and basketball Bump mapping for ball

58831 Texture maps for my project: Ball: https://carloschapeton.com/workstuff/simpleMan/textures/basketball.png

15906 Bump map: https://carloschapeton.com/workstuff/simpleMan/textures/basketballBump.png

12166 Floor: I took a picture of a wooden tile using my phone since it was the closest to the wood type of a basketball court.

My Project Progress

Progress 1: I've created the vertices for the sphere in OpenGL following the source: http://www.songho.ca/opengl/gl_sphere.html

23444 Restart and Progress 1: I've created the floor and wall, and placed the sphere in the desired position with lighting. However, I realized from this that the texture map is incorrect for the two discs; the wall and floor. So, next step I will add my texture maps to see it better in order to fix it.

28928 Progress 2: I added texture maps for the ball and floor, no bump map yet, but the texture map is still incorrect for the floor, so I'm still working on that.

79488 Progress 3: I made the squares of the checkboard rectangles, so I can add texture maps to create the basketball court floor. I will retake some pictures of my table top and add the new texture maps after editing the pictures also.

76287 Progress 4:

129560 Progress 5: I am currently working on having multiple lighting, and the rotation matrix to rotate the ball texture.

107443 Progress 6:

93151 Progress 7: I attempted to add the bump map but the color being ignored is not correct. Note: Bump maps affect the surface normal, not the color.

90319 Progress 8: I tried to work on the rotation matrix again.

102604 Progress 9:

98236 Progress 10 and Final Result: I had trouble getting the texture map to slightly turn at an angle to look like the ball in the image I wanted to recreate. I also had trouble getting the bump map for the ball. I did end up getting multiple results but none looked correct. In the 3480/proj folder

Lab-3: Rotation

Screenshot of Rotating Selfie Dog When calling render() after adjusting the angle, the image flashes and it just gets out of controls. So only rotates when the G key is pressed.

73592 There are "holes" in the image, and that causes the image to not print correctly or smoothly.

Circle - Key 1

7722 RGB Gradient Colored Triangle - Key 9

9898 Lab 4 - Art (Key b) I was going for a 3D look. So a ball appears in the middle of the screen when key 'b' is pressed with a colorful checked background. A bright red to light blue gradient from left to right and a brighter blue to yellow from top to bottom.
