Development Logs[edit]

Community Bonding Period


Monday, July 1st, 2024[edit]

Downloaded the code from the repo of fall rainy in order to have a common base source code. Then, installed different libraries (like pytorch) to make it work.

Tuesday, July 2st, 2024[edit]

Implemented a different version of the neural network (NIF) to make it work with hit/miss task. Got a 0.99 accuracy with bounding sphere approach in the training set.

Wednesday, July 3st, 2024[edit]

Compared a normal rendering with the neural network (NIF) one: results are still far from being acceptable.

Thursday, July 4st, 2024[edit]

Got an average accuracy of 50% with NIF in predicting the true rendering. Tried with a simple KNN with a billion rays stored, got always 50% of accuracy. -> This means that there are some errors in the pipeline (maybe in generating the rays or conversions in spherical coordinates) because the KNN should be better than the random classifier with a billion rays of training set.

Friday, July 5st, 2024[edit]

Solved issues with rendering, got a maximum accuracy of 98.6% with the true rendering (bounding sphere sampling). Pay attention that this result has been achieved only with a single render.

Saturday, July 6st, 2024[edit]

Implemented a benchmark function that generate different angles of the object (test set). Implemented a different version of loss function (symmetric). Got a maximum accuracy of 98.8% and this result is unbiased -> high confidence.

Sunday, July 7st, 2024[edit]

Implemented a grid encoding approach => results are still of the order of 98.8%.

Monday, July 8st, 2024[edit]

Tried with different optimizers, results improved to 99.1% with Nesterov Adam that converges faster and it is very stable between epochs.

Tuesday, July 9st, 2024[edit]

Started organizing source code to better understand the workflow.

Wednesday, July 10st, 2024[edit]

Continuing organizing source code.

Friday, July 12st, 2024[edit]

Finished organizing source code.

Sunday, July 14st, 2024[edit]

Added acceleration and support for Metal (Mac OS).

Monday, July 15st, 2024[edit]

Implemented a positional encoding like in NeRF's work -> results improved to 99.3%.
