"Noise" refers to the grainy effect of an image.
The more "Noisy" an image is, the more grainy it looks which usually means the quality is really bad.
The less "Noisy" an image is, the less grainy it looks which means the quality is very good.]]> 2021-12-02 20:11:55 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926023406 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926073849 2021-12-02 20:48:31 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926073849 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926136756 https://developer.nvidia.com/optix-denoiser

Uses GPU-accelerated artificial intelligence to dramatically reduce the time to render a high fidelity image that is visually noiseless. This provides ultra-fast interactive feedback to artists, allowing them to iterate their creative decisions more quickly and achieve their final product much faster.]]> 2021-12-02 21:41:33 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926136756 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926154707 https://developer.nvidia.com/blog/nvidia-real-time-denoiser-delivers-best-in-class-denoising-in-watch-dogs-legion/]]> 2021-12-02 21:56:42 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926154707 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926223883 https://knowledge.autodesk.com/support/3ds-max/troubleshooting/caas/sfdcarticles/sfdcarticles/Single-high-resolution-frame-with-Arnold-CPU-takes-a-long-time-to-render-in-3ds-Max.html

When rendering a scene file in 3ds Max with Arnold CPU renderer, the scene takes an extremely long time to complete the Arnold preview pass and final rendered frame when the resolution is higher than 2K.

For example, rendering a 4K image takes up to 12 hours.
So a 2 min render animation would take 12 hours to finish if the resolution is higher than 2K in Maya]]> 2021-12-02 23:05:16 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926223883 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926229424 https://www.youtube.com/watch?v=eGAjsSNtX6E

Key notes:
- Optix uses less samples but produces the result way faster better compared to blender's render.
-What Blender can produce with 20,000 samples; Optix can achieve with just 200.
-Might not give the best result for animations since the sample generated aren't consistent thus despite not looking grainy, the scene would have an odd filter to it whenever something moves in the scene. ]]> 2021-12-02 23:11:51 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926229424 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1926240471 https://docs.arnoldrenderer.com/pages/viewpage.action?pageId=40111301

Sampling is the process where the software collects information from the scene. This is done by sending out rays from the camera until the ray hits an object in the scene. When that ray hits something it performs some calculations that will eventually return a piece of information about that object such as the colour.

Key Notes:
-Aron works with simulated VistaVision optics - the default in Autodesk's Maya, which is used for the majority of the workflow, including model construction and lighting. "We render with [Maya plug-in] Mental Ray," he adds, "and we use [The Foundry's] Nuke for compositing. We try to keep the software list low, because it allows us to be agile."

-Something Kilian and I gravitated toward was Ralph's line work - he did a lot of pencil lines on his paintings. So instead of a lot of geometry in our CG models, we incorporate a lot of surface-drawn lines, which give a nice hand-rendered feel and the [illusion] of detail, which works well for our pipeline and rendering ability."

-Could these renders in the show be improved if the art team were able to make more experiment samples during the pre-production with OptiX which would benefit the show's visuals or reduce timetables as they are able to get results faster.]]> 2021-12-03 10:49:22 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1927095403 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1927669143 https://www.proquest.com/docview/2436897733/fulltext/90BC1DD4BDF54160PQ/1?accountid=26453

Key Notes:
- The last process where the production simulated hair, fur, feathers, etc. for the animals and had to make sure that the light bounced off realisitcally on the surface of these CG characters could benefit from OptiX as the creative team behind this part of the job would be able to produce multiple samples and experiments to get the best result for the final film.]]> 2021-12-03 16:04:51 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1927669143 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1927957639 https://docs.arnoldrenderer.com/display/A5AFMUG/Introduction+to+Arnold+for+Maya]]> 2021-12-03 18:39:00 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1927957639 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928213089 https://diglib.eg.org/bitstream/handle/10.2312/egsh.20101049.065-068/065-068.pdf?sequence=1&isAllowed=y

Key Notes:
-If the total render time is an hour or more, you want to use the “Frame Sequence” approach. For example, if you are rendering a one-minute video clip for the film, there will be (60 seconds per minute) X (24 frames per second) or 1440 frames per minute. If each frame takes 30 seconds to render, then you will be able to render two frames per minute, or need 720 minutes (12 hours) of render time.]]> 2021-12-03 23:55:02 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928273192 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928719655 https://docs.chaos.com/display/VMAYA/Denoiser#expand-UIPathDisplayRenderSettingsbuttonRenderElementstabDenoiser]]> 2021-12-04 12:37:07 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928719655 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928721185 https://docs.arnoldrenderer.com/display/A5AFMUG/Arnold+Denoiser]]> 2021-12-04 12:39:22 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928721185 pacorin2 https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1928745902 https://www.youtube.com/watch?v=n87U29SOapQ&t=3s

Key Notes:
-ReBLUR - Provides more realistic lighting with better temporal stability (Anti-aliasing) and is 50% faster

-SIGMA - A fast shadow denoiser. this can denoise shadows from any type of light sources such as sunlight or local lights 

-ReLAX - Denoises raytraced signals in the scene which yields better anti-aliasing and is very responsive to changing light conditions.

Key Notes:
- Disney's Renderman was not optimized by the world of the movie thus the time it took to render a frame was 1000 hours since the scene contained 8 million lights which is an overwhelming amount for Disney's rendering software.
- The team managed to reduce the render time from 1000 hours to 50 hours a frame by developing a new system that would essentially render the closest lights to their full quality and give a bare minimum render to lights that are far away from the scene.]]> 2021-12-05 19:15:37 UTC https://padlet.com/pacorin2/kg8p3rrh3k6kiqca/wish/1929828837
