All the reconstruction magic is working. Fast winding numbers outperform the old vote-based method by a large margin and make it very easy to reconstruct the trees when rotated or transformed in any affine way. I can skip other import correction steps, since it all gets corrected with the fast winding numbers and cell assignment.… Continue reading Reconstruction

For the times I have been able to work, I have managed to make a few good things. Such as improving the performance of incremental sculpting items from a few hundred operations a second, to around 10000 per second on a modern and beefy machine. (An operation being, carving one shape from another). Memory pools… Continue reading Summer/Fall 2021

I spend a little bit of my vacation time to wrap up some personal project tasks that have been simmering for the past 11 months for all the pie in the sky ideas I could come up with to make the library run faster and with less memory. At the end of it, I have… Continue reading No reason to squeeze anymore

Life is strange and overwhelming at times. So, my personal project work has been done behind curtains for the past year or so. Some reasons be personal, depressing, difficult to explain, hick-ups and/or related to a separation and I was starting to feel Anhedonic. But, I have not been idle at all. I just took… Continue reading What have you been doing for the past year?

The last month has been a bit of a ride. Elin needed to have an operation, so I have had to deal with baby issues almost exclusively, picking up, dropping off and most daily maintenance. We are about to sign a purchase agreement for an apt, so that kept us busy through a few nights,… Continue reading Solid Mesh Reconstruction

I got out of the rhythm of blogging and was always waiting for my current little batch of tasks to be done with. So for the last month, I have been focusing on creating a polyhedral previewer of the actual robust modelling kernel. Using the intermediate data generated from the robust plane and fixed point… Continue reading 4 years, 3 months, 16 days

Integrated a Fast Box Intersection library into a geometry utility dll I have for various computational needs. The library is very rich in templates and depends on boost, which makes it a little less desirable to use, but I did anyway. So, using this library, I can both test for self intersections, and bipartite intersections.… Continue reading 4 years, 2 months, 20 days

While I was working on a simple feature of translating and updating my AABB trees, I got dragged into fixing, simplifying, removing and refactoring some things. Removing support for UVs withing my building tool since keeping tally of that information just invites complications I don't want. Unifying mesh concepts and objects so that there is… Continue reading 4 years, 2 months, 7 days

For the last 2 weeks, this household has been ill. We got the stomach flu about 2 weeks ago, and our youngest got some viral infection that has lasted for a week. So, anything I have done on my project has been quite minimal for the last 10 days. I am hoping that the holidays… Continue reading 4 years, 1 month, 28 days

Playing with the AABB tree and queries, there are a few things that have popped up. Such as, for doing ray and point tests, my BSP trees are 3 - 4x faster. But, when making broader queries such as testing a bound against an AABB tree, it is quite fast at handing you all the… Continue reading 4 years, 1 month, 16 days
