I'm trying to use a compute shader to do three-dimensional physical simulations but having trouble storing anything into my 3D texture. My shaders compile successfully but when reading back any value from the 3D texture I get a zero vector. I haven't used compute shaders before either so I'm not sure if I'm even distributing the work load properly in order to achieve what I want.

I've isolated the problem in a small example here. Basically the compute.glsl shader has a uniform image3D and uses imageStore to write a vec4(1,1,0,1) into gl_WorkGroupID. In C++ I create a 100x100x100 3D texture and bind it to the shader's uniform, then I call glDispatchCompute(100,100,100) - to my knowledge, this will create 1,000,000 jobs/shader invocations, one for each coordinate in the texture. In my view.glsl fragment shader I read the value of a random coordinate (in this case (3,5,7)) and output that. I use this shade a cube object.

Everything I've tried results in a black cube being output:

Here's my code (I've been following along with learnopengl.com so it's mostly the same boiler plate stuff except I extended the shader class to handle compute shaders):

I would like to call form submit button after done if ajax called.
My page has two button.
One is upload image by ajax.
Another one is submit button.

I'm trying to write a bare minimum GPU raycaster using compute shaders in OpenGL. I'm confident the raycasting itself is functional, as I've gotten clean outlines of bounding boxes via a ray-box intersection algorithm.

However, when attempting ray-triangle intersection, I get strange artifacts. My shader is programmed to simply test for a ray-triangle intersection, and color the pixel white if an intersection was found and black otherwise. Instead of the expected behavior, when the triangle should be visible onscreen, the screen is instead filled with black and white squares/blocks/tiles which flicker randomly like TV static. The squares are at most 8x8 pixels (the size of my compute shader blocks), although there are dots as small as single pixels as well. The white blocks generally lie in the expected area of my triangle, although sometimes they are spread out across the bottom of the screen as well.

Here is a video of the artifact. In my full shader the camera can be rotated around and the shape appears more triangle-like, but the flickering artifact is the key issue and still appears in this video which I generated from the following minimal version of my shader code:

Just looking for guidance or even a general outline on approach here.

I am using azure search to OCR a batch of pdfs. I have turned on hit highlighting and I am successfully getting results back there that I am looping through / displaying in my view for the end user. I was looking on expanding that functionality to show the pdf images with the highlighting on the images themselves like in the JFK azure example. I am not proficient in react and seem to be getting lost there.

I am assuming I need to save off the OCR images to a data store for reference using the normalized_images that are created? I do have pdfs locally I can load but assume the OCR images maybe different. Have turned on GeneratedNormalizedImagesPerPage and turned on cache which creates files in my storage account.

Then I assume I need to pull the associated image, display it, use the highlight results and pull a corresponding bounding box where the phrase was detected? Problem with that approach is that I do not see any association between the highlight hit and the location (bounding box) of the hit nor the associated image file the hit was on.

Probably way off on approach here but any guidance is appreciated.

Edit 1 I did noticed the items on this page in the JFK example: https://github.com/microsoft/AzureSearch_JFK_Files/tree/master/JfkWebApiSkills/JfkWebApiSkills Would trying to replicate the ImageStore (so those are stored in my storage account) and then the HocrGenerator (appears to handle points in a doc) into my skillset for my index be the approach?

While I'm trying upload image to server (000webhost) through my android app by using php mysql I'M facing directry issue.

Code where i am calling function in UpdateInfo.php to upload image.

I have a total of two textures, the first is used as a framebuffer to work with inside a computeshader, which is later blitted using BlitFramebuffer(...). The second is supposed to be an OpenGL array texture, which is used to look up textures and copy them onto the framebuffer. It's created in the following way:

I'm following Infinity Ward's approach to ray tracing shadows where they reconstruct the world position from the depth buffer and cast a ray from that towards the light. I find that I get really bad shadow acne using this method with 1 ray per pixel, probably because of numerical errors. The obvious fix is moving the world position a small amount in the normal direction, but I do not have access to normals. I figure it might go away once I shoot multiple rays per pixel but for performance reasons I'm trying to stick to 1. Any options or am I just doomed without access to normals?

To store images I'm using Spring Content JPA strategy. My test profile has HSQLDB in-memory implementation. Is there a more convenient way to populate DB with images? For now, I have a solution to create a folder with images and then upload them manually on startup. As I understand, to get rid of the image folder I can upload them to SQLite and then fetch data from it, but maybe there is a better way?

I need to read depth texture data in OpenGL Compute shader.

this is texture intialize code.
