kandi X-RAY | bloom Summary

bloom is a Rust library typically used in Server, Caching applications. bloom has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

Bloom can be hot-plugged to sit between your existing Load Balancers (eg. NGINX), and your API workers (eg. NodeJS). It has been initially built to reduce the workload and drastically reduce CPU usage in case of API traffic spike, or DOS / DDoS attacks. A simpler caching approach could have been to enable caching at the Load Balancer level for HTTP read methods (GET, HEAD, OPTIONS). Although simple as a solution, it would not work with a REST API. REST API serve dynamic content by nature, that rely heavily on Authorization headers. Also, any cache needs to be purged at some point, if the content in cache becomes stale due to data updates in some database. NGINX Lua scripts could do that job just fine, you say! Well, I firmly believe Load Balancers should be simple, and be based on configuration only, without scripting. As Load Balancers are the entry point to all your HTTP / WebSocket services, you’d want to avoid frequent deployments and custom code there, and handoff that caching complexity to a dedicated middleware component.

            Binding Images without using them all in Vulkan
            Asked 2022-Jan-13 at 03:08

            I trying to create a bloom effect for my vulkan game-engine. To implement this I use several bulring pass, in each one I read from one image and render/write a slightly more blurry picture to a other. After each draw pass i swap the role of these images(And using barriers), That means - the one was a render target became a shader resource and the one used as a shader resource became a target. I bind both of these images on same descriptor set to save unnecessary 'VkBindDescriptorSet' calls, but the validation layer tell me that if I want to bind a descriptors of images those all image's layout must be 'VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL' even if the shader used/read only from one of them at any given time(The shader read only from The one that currently in the 'VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL' state). Is this over-caution of the validationlayer? or the bindung is actually failed.

            When i worked with DirectX12 I not had this debuger isue!

            I would be happy for an answer or an idea for a solution, and I am sorry about my English.

            ANSWER

            Answered 2022-Jan-13 at 03:08

            Assuming your shader actually doesn't use the sampler when its image is bound to it, the validation layer is incorrect (not that it can know). The Vulkan standard only requires that the attached image subresources are not used:

            Image subresources used as attachments in the current render pass must not be accessed in any way other than as an attachment by [a rendering command], ...

            "Access" is defined by the Vulkan memory model, which for a bound image, involves invoking an image access command. So long as you don't do that to the descriptor, it is not "accessed", and thus does not violate this rule.

            That being said, ping-ponging between images without using input attachments requires stopping and starting a render pass, not to mention the execution barriers between each pass. The cost of VkBindDescriptorSet will be a rounding error in your GPU profiling data next to all of that.

            So you should just change descriptor sets and shut the validation layer up.

            After several hours of trial and error, I finally figured out what the problem was, it like many other bugs it turned out to be a stupid one. The order of the tags in the proto file's message has been changed (a new field was added at the top and all of the other fields were pushed downward). The server was using the new definition, while the client was using the old one. When the client tried to call an endpoint, the tags did not match.

            All I had to do is re-generate the files for the client stub.

            (unity) Is there a way to apply bloom to a specific object?
            Asked 2021-Dec-18 at 02:17

            I've currently noticed that, if i uncheck the "is Global" checkbox on the Bloom Effect of a Post Processing Volume, even thought I adjusted my layer to affect one in particular, the Bloom doesnt apply to that layer I've set in the P-p layer. In fact, it doesn't apply at all. Either it sets bloom for everything in the scene, or it doesn't.

            Extras: I have no Pipeline asset, maybe thats the issue, but I've tried to setting one LRP (because for some reason URP in my 2019.2.17f1 version doenst exist) and it just breaks all my materials that i use for Particle Systems (Particles/Standard Unlit) even if i upgrade them for LRP materials.

            Any ideas? If it's possible to deliver a solution to both these problems excellent, but the main one is the title question.

            Answered 2021-Dec-17 at 22:39

            The is global might sound confusing at first. Ultimately it does not mean where to apply the post processing effect, but when to apply the effect. If it is set to Global, it will always be applied, otherwise you can set a layer and a border that triggers the effect.

            The general approach is to only set emission to materials where you want the effect to take place. If your Materials are to dark otherwise you should adjust the ambient lighting settings.

            Atleast in URP there are some work arounds for older versions like this, but afaik this does not work in 2020.3 since they made some changes on URP and the camera system.

            edit: on the video Chris Hull Chris Hull game an answer for how to do it with the new system

            @Mezzanine Add your actual game objects to a created bloom layer. Create two cameras and set one of them to cull everything except that bloom layer you made. Set the other to only cull the bloom layer. Then you can set your camera to overlay and it will be added to the other. You can then use separate post process stacks on these cameras. Note that you can only bloom objects in the background with this technique as if you add bloom to an overlay camera, for some reason it just adds bloom to everything rather than just the things in that camera view. Doesn't make much sense and makes the purpose of the layers redundant in my opinion. If you can find a way to add post process to the overlay camera before it is added to the final image, to do let me know.

            i have not tested that yet, but i presume it's still valid.
