camera calibration for partial occlusions

I hope you guys understand me this time around, it seems every question I ask is not real or vague or something. I am using OpenCV and C++ to create a 3D image reconstruction program. I have been able to implement the camera calibration aspect, but…

Issues constructing a Texture2D from a byte[] extracted from an XRCpuImage in Unity

I am trying to create an AR debugging application that takes information from a server (the phone) and displays it on a client (the computer). I am using the AROcclusionManager component to get environmentDepthImage information. I am using a native…

Is there a good term for reconstructing partially-occluded 3D objects in Computer Vision by extrapolating edges?

What I have in mind is something like techniques where visible edges, maybe along with estimated tangent vectors relative to an estimated view-angle, are used to extrapolate likely positions for invisible edges. E.g. if an object appears to be a…

Check if a quad is fully covered by a set of others

I am doing a lot of voxel game development and I am optimizing the light engine. The idea is, that I can check if light can enter a block or not. To break down the question to the minimal, here it is: I got a set of quads. Now I need to check if the…

How do dense stereo matching algorithms, such as LEAStereo make disparity predictions at occluded regions?

As far as I understand, stereo matching algorithms should fail predicting the disparity at occluded regions. However, there are plenty learning based methods that produce a fully dense disparity map (just look at the KITTI stereo benchmark list, you…

Question about unity occlusion culling not working properly

I am currently using occlusion culling in Unity 3D. However, I didn't like the current map size, so when I increased the scale by 1.5 times, the following phenomenon did not work normally. enter image description here (this is the working…

I am trying to create an audio occlusion system, it kind of works however when I try to set the LPF frequency, it doesn't change (ue4)

When I print out what the Low Pass Filter is its fine, however when I get the LPF frequency from the audio component reference it doesn't change. any ideas or suggestions? Here is a link to my code:https://blueprintue.com/blueprint/x0hnwumi/

aoMap/Shadows inversed in ThreeJS

I am currently trying to display a 3D room using Three.JS. I bought the model on SketchFab and I am using its GLTF format. This model includes "baked-in" shadows using an occlusion map and a specular glossiness map. I do not plan on having dynamic…

How to handle mouse events on occluded (overlapped) display objects in flash/flex?

my questions is little similar to some of the questions asked previously about overlapped sprites/movieclips like this. But my requirement is slightly different than them. I want to handle the mouseevents for all the sprites on the stage including…

Three.js Visual indication or Effect to show when an object is occluded

I’m building a program where you control a small avatar (this is a basic circle geometry or plane) that traverses through a scene filled with 3D Models and shapes. I’d like to achieve an effect similar to those found in many video games where you…

How to correctly visualize AO map contribution in A-Frame

I created a room model in Blender and baked Ambient Occlusion using a dedicated UV set. I then created a new material with the baked AO image as a texture and applied it to the whole model. Visualization in Blender is correct. I would like to…

OnBecameVisible() not call when gameObjects is on camera's field / UNITY

i want to optimise my mobile game by not showing gameObjects that are not in the camera's field. I can't do Occlusion Culling because those gameObjects are instantiated and not static. So i used void OnBecameInvisible(){ Renderer.enabled = false;…

Mirrors with deferred rendering and ambient occlusion

As you can tell from the title, I'm trying to create the mirror reflection while using deferred rendering and ambient occlusion. For ambient occlusion I'm specifically using the ssao algorithm. To create the mirror I use the basic idea of reflecting…
