leocad VS wyhash

For an alternative have a look to LeoCAD:

- compatible with the LDraw Standard (used by BrinkLink Studio & LEGO Digital Designer)

- work on Windows, Mac & Linux

- GPL 2

This is a short animation of a Lego Star Wars X-Wing taking off. I built the models using LeoCAD, and then exported them from there into Blender 3.4. The Lego material was made by me (you can download it here). Textures are from AmbientCG, and the HDRI is from Poly Haven. This render was my first time using Natron for some compositing. The animation was rendered at 1080p with 1024 samples.

Can you just export a minifig from LeoCAD

I thought the same at first but nope, it’s definitely called LeoCAD: https://www.leocad.org/

This is a Lego Architecture model of San Francisco. I built the model using LeoCAD, and then exported it into Blender 3.3. I did a bit of geometry cleanup so I could subdivide and bevel the edges of some pieces. I made the Lego material myself (you can download it here). Most of the textures are from AmbientCG. The scene is lit by an HDRI from Poly Haven. Rendered at 4k with 4096 samples. I normally use the undenoised (non-denoised? adenoised? noiseful?) renders as the main ones, but because this is an interior scene, I used the denoised versions. For the undenoised renders, as well as scene views and the compositing setup, check out whocompute.com/img/62a9f8

A Lego X-Wing I made. I built the model in LeoCAD, so all the parts are from there. It is based on Lego set #75218, with some modifications as not all the parts in the set were available in the parts library. I exported it, and did some geometry cleanup so I could bevel the edges of the pieces. The material was made by me, with scratch and fingerprint textures from AmbientCG. Lighting was done by 3 area lamps and a sun lamp. I rendered it at 8192 samples. I didn't denoise it because I thought it looked better with a little grain. Denoised and uncomposited versions are available on my website: https://whocompute.com/img/9cfd85 Feedback is welcome.

I recently switched to wyhash as it seems to have a good combination of speed and stability.

wyhash is a decent option for if you don't need a cryptographical quality hash

New Bare Hash Map: 2X-3X Speedup over SOTA\ (32 comments)

I feel like you’d want something a bit safer than “we don’t store the keys and just rely on the hash to be really good” [1], putting “please do not use this for serious tasks” in a comment embedded in the header file isn’t a clear enough warning.

It’s not clear to me that that probability of collision assumptions hold. It’s basically assuming that the hashing is perfect and distributes any inputs to the full 64-bit space with uniform probability. That’s the usual hash map / randomized algorithm hope, but does BigCrush or similar avalanche testing really prove that? (Presumably not, otherwise there wouldn’t be image attacks for things like md5).
