kandi X-RAY | voxelizer Summary

voxelizer is a C++ library typically used in Hardware, GPU applications. voxelizer has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a simple voxelization engine made for MIT's 6.807 Computational Fabrication. Given a .obj mesh, this will output a voxel grid in the form of another .obj file. This voxelizer relies on CUDA for acceleration of the inherently parallel voxelization process. WARNING: this can generate some BIG files if you specify a .obj output and make your computer very sad. Keep the resolution below around 128 for safety. Higher can be achieved, but you will want to use binvox output. Using resolution of 256 I generated a 4.7 GB voxel obj file containing over 67 million vertices. This just about crashed my computer as I obliterated my poor swap space. On the bright side, it only took <2 seconds to generate...

QUESTION

Question about segmentation fault on std::stack push

Asked 2019-Aug-13 at 10:10

I am working on a octree traversal algorithm. The current implementation uses a std::queue for such purpose, working flawlessly. However, I would like to use for such traversal a std::stack, as a depth first search will give better performance, avoiding testing non needed nodes.

However, when changing from one structure to another, I start getting segmentation faults on the push() function. Here is the stack report from gdb:

QUESTION

oct tree generation going wrong at the last step

Asked 2018-Jun-09 at 17:33

NOTE: THIS QUESTION HAS BEEN DRASTICALLY EDITED FROM ITS ORIGINAL FORM

I am attempting to create a logarithmic raytracer by implementing an oct tree data structure combined with voxelization to achieve fast ray tracing.

Currently I am having issues with the ray collision detection.

The expected output should be the voxelized stanford dragon with its normal map.

Currrently the issue is that some regions are transparent:

Transparent regions:

From these images it should be clear that the geometry is correct, but the collision checks are wrong.

There are 2 fragment shaders involved in this process:

The error comes from the sorting function as someone in the comments mentioned although not for the same reasons.

What has happened is that, I thought the sort function would modify the arrays passed to it, but it seems to be copying the data, so it does not return anything.

QUESTION

how to use vtkImageReSlice?

Asked 2018-Mar-04 at 22:47

I am trying to use vtkImageReSlicer to extract a 2d slice from a 3d vtkImageData object. But I can't seem to get the recipe right. Am I doing it right?
I am also a bit confused about ResliceAxes Matrix. Does it represent a cutting plane? If I move the ReSliceAxes origin will it also move the cutting plane? When I call Update on the vtkImageReSlicer, the program crashes. But when I don't call it, the output is empty.

Here's what I have so far.

I have never used vtkImageReslice, but I have used vtkExtractVOI for vtkImageData, which allows you to achieve a similar result, I think. Here is your example modified with the latter, instead:
