Nice demo! We need more of this approach. You really can achieve amazing stuff with just plain e.g. OpenGL optimized for your rendering needs. With todays GPU acceleration capabilities we could have town-building games with huge map resolut

Classic fallacy fallacy. The fallacy fallacy is a fallacy that asserts that because an argument is fallacious, the conclusion of the argument is false.

Specifically I was referring to the Parsis and their Zoroastrian teachings. The introduction to the quoted book has put it in those words: https://www.sacred-texts.com/zor/sbe04/sbe0402.htm#page_xi The Zend-Avesta

Sounds like the ancients had similar thoughts as “We will not declare her dead until she is warm and dead.”: https://www.sacred-texts.com/zor/sbe04/sbe0411.htm From The Zend Avesta, Part I - FARGARD V. 10 (34). O

Burn it to ash, collect info about the ash and reconstruct - no problem. But if you burn it in a way, that the only remains are "random thermal radiation" all the information is lost and we have a serious paradox to resolve...

There is a minimum contrast specified for a reason, because more contrast is better to read. Modern designers argue that high contrast is "harder on the eyes" and they seem to prefer solid colored boxes. It is a real pitty, infe

Hm yes. I also played with a few a examples. I have to admit, the order seems to only be really irrelevant when averaging rotations around one axis to avoid triangles. Thanks for pointing out. For averaging rotations that are similar the di

Slerp is no binary operator, but suppose we only look at the two quaternions, then it is "commutative". You can swap both quaternions, but you must use (1-t) for the interpolation factor instead of just t. Wikipedia[1] lists some

by xaedes 4y ago
Oh you can absolutely average rotation quaternions, even weighted. You just use regular online computation of mean, express it in terms of linear mix operations (x k + (1-k) y) and then use quaternion slerp for the linear mix: mean =

I think the worst thing about student surveillance software is that it teaches a whole generation that it is normal to be and work under surveillance.

That new definition sounds pretty broad. Does that make vitamin C a vaccine? I think it also stimulates the body's immune response against diseases.

The analogy is not perfect by any means, but lets look at a regular computer monitor. Is the area/space in front of it the same (state) as the area behind the monitor? With respect to "is there a monitor in this place" they a

Hahaha... yea. I actually had to submit my thesis with - lets say not the best - results because I did not use the actual timesteps. My inertial navigation system for an autonomous rc model car would estimate paths that where kinda right, b

by xaedes 5y ago
When you implement a Kalman filter, make sure to use the actual timesteps (i.e. delta time = now - last) instead of a theoretical fixed timestep (e.g. delta time = 0.1s or similar) or averaged timestep. Makes all the difference

Won't be easy, drones are small and fast. RGB based detection will probably be too slow and error prone. Rather put active IR LEDs or similar markings which can be easily detected, use cameras which only let through IR and high framera

Really? Dark cyan on light pink? Where did the colors go wrong? It does reduce readability a lot. Why do people feel the need to make websites barely readable by going for low contrast?
