| <b>Project Summary</b> | ||
| <br /> | ||
| With the codebase given in homework 4, we plan to implement | ||
| physically based sound onto computer animations. We will synthesize | ||
| appropriate sounds, based on different materials, forces, and other | ||
| physical processes of an animation. | ||
| </p> | ||
| <p> | ||
| <b>Current Project Progress</b> | ||
| <br /> | ||
| Within the past week and a half we have gone through all the code of | ||
| HW 4 to understand the rendering pipeline of objects for the OpenGL | ||
| GUI. We realized that adding other objects to render to HW 4 is a | ||
| much more intricate process than we initially anticipated. We | ||
| previously anticipated that we would be able to convert dae files of | ||
| previous HWs to .json and render them in HW4, but upon investigating | ||
| the code that is not possible because we do not have a parser for | ||
| other objects that are not a plane, sphere, or cloth. Currently, we | ||
| are investigating openGL-tutorial.org in hopes that we can obtain | ||
| and implement a parser that would allow us to render other rigid | ||
| objects into the HW 4 GUI. In the last week and a half, we also | ||
| researched the PortAudio C++ library to implement sound into the | ||
| existing HW 4 project. We adjusted the CMakeLists.txt files and | ||
| project directory to build and implement the library, and a sine | ||
| tone plays for 15 seconds upon opening the application. | ||
| </p> | ||
| <p> | ||
| <b>Next Steps</b> | ||
| <br /> | ||
| The bunny found in Homework 3 is the Stanford bunny, and is | ||
| available in the PLY format online. Our approach to rendering the | ||
| bunny will be to create our own class that inherits from | ||
| CollisionObject. | ||
| <br /> | ||
| Our new object can be similar to the sphere object, as it already | ||
| contains a mesh structure. We will look into implementing a parser | ||
| for either the PLY or the .obj format detailed in | ||
| openGL-tutorial.org to read the bunny object into the required mesh | ||
| struct. We were hoping to adjust the sound to correspond with the | ||
| collisions by the bunny and cloth. We hope to first implement being | ||
| able to play a sound when a collision occurs, then implement playing | ||
| a sound that dynamically changes depending on the types of | ||
| collisions and materials being used. Now that we have sounds | ||
| playing, we can investigate where in the codebase we should play | ||
| sound and how to play sound buffers that dynamically change | ||
| depending on collisions. Due to our difficulties with adding other | ||
| rigid objects to our HW 4 framework our previous plan from our Final | ||
| Project Proposal needed to be updated. With our current progress and | ||
| remaining time left for the project our new work plan is as follows: | ||
| </p> | ||
| <p> | ||
| <b>Week 3</b> | ||
| <br /> | ||
| Implement other rigid body objects to HW4 framework | ||
| <br /> | ||
| Implement physical simulation for our added objects, rigid-motion | ||
| simulation of CBbunny onto the plane (our “bounce”). | ||
| <br /> | ||
| Implement cloth collisions with rigid-bodies (CBbunny) | ||
| <br /> | ||
| Implement playing sounds through speakers | ||
| <br /> | ||
| If we cannot implement other rigid body objects to our HW4 framework | ||
| by the end of this week we will continue by adding simulation to the | ||
| sphere. As well as, add sphere interactions with planes and cloths. | ||
| </p> | ||
| <p> | ||
| <b>Week 4</b> | ||
| <br /> | ||
| Implement cloth collisions with movements such as rubbing (if time | ||
| permits pulling as well) | ||
| <br /> | ||
| Research sounds based off rubbing of cloth (& pulling) | ||
| <br /> | ||
| Implement collisions with other materials such as metal or wood | ||
| <br /> | ||
| Research and implement sounds dependent on new materials | ||
| <br /> | ||
| Implement stretch goals such as sound between moving objects if time | ||
| permits | ||
