- Ray Tracer Assignment: Checkpoint 6
Transmission At the intersection point, in addition to the reflection ray and the shadow ray, you must follow the transmission ray (through the intersected object) to determine its color contribution to the intersection point. Use an index of refraction of 1.0 for the air around your objects. The transmission ray moves into the object from [...]
- Ray Tracer Assignment: Checkpoint 5
Reflection At the intersection point, you’ll need to obtain the reflection ray in addition to the shadow ray, and to follow the reflection ray to determine its color contribution to the intersection point. Note that the reflected ray is the reflection of the incoming ray (from the camera, or another reflected ray spawned from an [...]
- SLAM Visualization for Player: Midquarter Update
Midquarter Update What’s Been Done So Far The SLAM tutorial papers have been investigated. A cheap/fast version of SLAM has been developed that calculates the robot’s current position based on previous estimates and built probabilistic map using Markov-based localization. Basically, it evaluates a bunch of random points around the previous location and score each location [...]
- Probabilistic Mapping
This is a homework assignment for Mobile Robot Programming. A probabilistic map is built for a simulated pioneer robot using 8 sonar sensors. The sensor model used was just a really simple condition based model. However, more complicated model can be plugged in to deal with noise in the real world. I enjoyed watching the [...]
- Ray Tracer Assignment: Checkpoint 4
Procedural Shading Using the program from Checkpoint #3 (without extras), the task for this assignment is to add procedural shading to the ray tracer. Another procedural shading pattern using sine waves (Extra): Texture mapping (Extra):
- Ray Tracer Assignment: Checkpoint 3
Phong Illumination Using the program from checkpoint #2 (without extras), the task for this assignment is to add Phong Illumination to the ray tracer. On intersection, rather than return the color of the object hit, calculate the color at the intersection point using the Phong Illumination model. To apply the Phong model, if there is [...]
