            How to get parallel GPU pixel rendering? For voxel ray tracing
            Asked 2021-Apr-28 at 03:07

            I made a voxel raycaster in Unity using a compute shader and a texture. But at 1080p, it is limited to a view distance of only 100 at 30 fps. With no light bounces yet or anything, I am quite disappointed with this performance.

            I tried learning Vulkan and the best tutorials are based on rasterization, and I guess all I really want to do is compute pixels in parallel on the GPU. I am familiar with CUDA and I've read that is sometimes used for rendering? Or is there a simple way of just computing pixels in parallel in Vulcan? I've already got a template Vulkan project that opens a blank window. I don't need to get any data back from the GPU just render straight to the screen after giving it data.

            And with the code below would it be significantly faster in Vulkan as opposed to a Unity compute shader? It has A LOT of if/else statements in it which I have read is bad for GPUs but I can't think of any other way of writing it.

            EDIT: I optimized it as much as I could but it's still pretty slow, like 30 fps at 1080p.

            Here is the compute shader:

            ANSWER

            Answered 2021-Apr-04 at 10:11

            Compute shader is what it is: a program that runs on a GPU, be it on vulkan, or in Unity, so you are doing it in parallel either way. The point of vulkan, however, is that it gives you more control about the commands being executed on GPU - synchronization, memory, etc. So its not neccesseraly going to be faster in vulkan than in unity. So, what you should do is actually optimise your shaders.

            Also, the main problem with if/else is divergence within groups of invocations which operate in lock-step. So, if you can avoid it, the performance impact will be far lessened. These may help you with that.

            If you still want to do all that in vulkan...

            Since you are not going to do any of the triangle rasterisation, you probably won't need renderpasses or graphics pipelines that the tutorials generally show. Instead you are going to need a compute shader pipeline. Those are far simplier than graphics pipelines, only requiring one shader and the pipeline layout(the inputs and outputs are bound via descriptor sets).

            You just need to pass the swapchain image to the compute shader as a storage image in a descriptor (and of course any other data your shader may need, all are passed via descriptors). For that you need to specify VK_IMAGE_USAGE_STORAGE_BIT in your swapchain creation structure.

            Then, in your command buffer you bind the descriptor sets with image and other data, bind the compute pipeline, and dispatch it as you probably do in Unity. The swapchain presentation and submitting the command buffers shouldn't be different than how the graphics works in the tutorials.

            Text output from XML with XSLT with XSLT 1.0 (MSXML 6)
            Asked 2021-Feb-18 at 14:41

            I have a problem I cannot solve with xslt 1.0. A solution for XSLT 2.0 was already given and works fine (see further below).

            For each layer grouped by STRAT_ZONE the minimal values from DEPTHFROM_ZONE and maximum value DEPTHTO_ZONE are needed.

            Grouping by STRAT_ZONE seems not an option, because the attribute can repeat itself. A checkup line by line was an idea.

            Conditional Formatting with Script - Highlight Rows based on Custom Formula
            Asked 2021-Jan-18 at 11:37

            I have a Google Sheet that tracks attendance using a rolling calendar. It has multiple sheets and I want each sheet to have the same conditional formats. Initially this seemed easy, I wrote some script, got it to iterate through all of the sheets to copy the format in one cell to the entire sheet. It worked well, until it somehow deleted all of the conditional formats except one, =A$1=TODAY(). I have been trying to determine why it is doing this and how to fix it. I have tried setting up the conditional format in a non-moving cell (A1), but then the formulas don't work properly. They end up highlighting the wrong row. I have been looking at Google Sheets API Sheets as well, but am having trouble implementing it. Is there a way I can write a script to set up these conditional formatting rules and how? Any help is appreciated.

            I have provided a picture of what I am trying to accomplish as well the script I had been using and references, all of which is below.

            The basic layout of the sheet is shown in the picture. The picture also depicts what I am trying to accomplish with the conditional formats.

            The formatting rules are as follows (and in this order):

            1. Apply to Range: A1:NH (whole sheet)
              Custom Formula is: =A$1=TODAY()
              Background Color: Default Green Background (#b7e1cd)

            2. Apply to Range: C2:NH (everything except row 1 and columns A & B)
              Custom Formula is: =$B2>=10
              Background Color: Dark Red 1 (#cc0000)

            3. Apply to Range: C2:NH
              Custom Formula is: =$B2>=8
              Background Color: Light Red 2 (#ea9999)

            4. Apply to Range: C2:NH
              Custom Formula is: =$B2>=5
              Background Color: Light Orange 1 (#f6b26b)

            5. Apply to Range: C2:NH
              Custom Formula is: =$B2>=2
              Background Color: Light Yellow 2 (#ffe599)

            The formula in Column B is =SUM($C2:2) auto-filled to each row.
