Is this post 2.5? I thought (and I don't know the answer, hence why I'm asking) 2.5's interface was built on the Python API? I tried doing some Python stuff with it in the 2.4 days and thought it was pretty poor as well, have

I'd say a better comparison is that Blender is like to Nokia interface of Nxx phones 10 years ago before the iPhone. All the functionality's technically there, but it's often very convoluted to use it, and that doesn't n

C++ is still very heavily used in industries where speed (and memory compactness) matter. Games, simulation, VFX... For example, most software used to make film movies / CG imagery: from modelling (Maya, SI), to texturing (Mari), to re

Last few versions on Android they've totally broken from a usability perspective IMO: * Yellow location search button is now in the way * Moving the menu to the top means you can't use it one-handed now * The most useful thing in

Back in 2006/2007 when I was doing web development, I knew a few people at F5 and Zeus Technology (developers of application firewalls at the time), and they said The Great Firewall was using loads of F5 tech with deep packet inspectio

It was the problem, because doing REYES hiding you suffer the huge "overdrawing" issue, where you need to set the shading rate per object in the scene based on its size on screen such that it doesn't get too much shading. I

Because until last year when Pixar released PRMan 19 RIS, PRMan was not that good at ray tracing / path tracing - the REYES method of rendering and shading didn't scale as well for big complex scenes when global illumination and r

While batching (and reordering) can have a benefit overall for rendering, it can have a significant (depending on how thoroughly you do it) overhead, and Disney are primarily doing it because they use Ptex to do texturing, instead of the mo

That post doesn't really prove anything: obviously, if you can see you're heading towards another aircraft and it's likely you'll collide, you'll take evasive action irrespective of ATC control. I was talking more a

Is it really the F-16's pilot's responsibility to ensure separation when under ATC control? Doesn't the US have MARSA (Military Accepts Responsibility for Separation of Aircraft) rules that military flights can occasionally

Well obviously - depending on the helicopter and where its turboshaft (jet engines, with air inlets, but designed to create rotational energy rather than raw thrust) are mounted, it's quite possible for a drone to get sucked into the i

Per iteration, bi-directional is extra work too. Obviously these integration methods are much better at finding certain hard-to-find light paths/sources, but my point is that in VFX, it's generally good enough to fake stuff by jus

Exactly, with the move to RIS, they're in pure path-tracing now, and they're still behind Arnold generally from a performance perspective. Displacement and subd performance is still very impressive (compared to Arnold), but motion

There are very few scenes that need Bi-directional or VCM (in VFX, anyway) - in theory it converges faster for indirect illumination, but due to the fact both methods need to be used in incremental mode (1 sample per pixel over the entire

DNeg are still using Mantra (and Clarisse) for a fair amount of stuff (Ant-man is their first production using just RIS in PRMan 19/20), Framestore are solidly Arnold now, and Weta are using their own PRMan clone (but a path-tracer) ca

Yeah, that's one thing that's really putting me off looking at Rust - the possibility of it enforcing style in the future. Hanging braces style for C/C++ is rarely allowed in the coding standards I've had to use in the p

Well I still use it (and Python) for fun for my own high-performance stuff - there's no other language out there (yet, without having to install custom compilers) that allows speed, flexibility and encapsulation... Good points though -

I think CMake is one of the best (not saying it's perfect) C/C++ build systems I've used (used jam, make, automake, qmake, scons quite comprehensively, either via choice or under duress), and there are some things that are cl

Use something like CMake which is cross-platform, works very well in most cases and a lot of cross-platform open-source C++ libs are using already.

For feature film, CPU still largely rules the roost, thanks to insane memory requirements and the fact that properly SSE'd/AVX'd code isn't THAT much slower than GPUs for highly parallel stuff like raytracing when you&#x

Over standard similar arch i7s you mean? They support ECC ram, which is pretty important for some people. I believe the pre-fetchers are more aggressive on the Xeons as well, to make more use of the available memory bandwidth available with

What edit? My second comment? That was my original point regarding logic errors and not caring - yes, it may well be that Rust gives you much more confidence that you don't do invalid/wrong things. But that excludes logic errors (

In this case it does. I was more talking about the overall not caring theme. I'd hope that's only because they know the code so can make those sort of assumptions. Are you saying Rust can find and prevent at compile time logic err
