Is there a Performance Penalty for LOD objects with different topology?
I have a fairly complex-shaped object I've modeled, and in creating the LOD meshes, I've merged some verts, deleted some and even added some after in cases where this manipulation produced an n-gon. ...
Understanding inequality to equality in the Hartmann & Gribbs frustum planes extraction method
I've been reading this article on how to extract the plane equations from the view and projection matrices. And I can understand most of it. However, the only thing that is unclear to me (and that ...
Ray Tracing Bounding Volume Hierarchies nodes
I'm new to computer graphics programming so I apologize in advance if my question is stupid. I'm trying to implement a BVH for my ray tracer and I looked at some lectures explaining BVH. They all ...
Why is my raycaster so slow?
I'm trying to write a raycaster similar to Voxlap, but it's many times slower. I've tried octrees, but the performance gains are marginal- only 10 to 20 percent. I use the algorithm from this site: ...
Fuse 3D-Points in Bundle Adjustment? [closed]
(Crossposting from here: https://softwareengineering.stackexchange.com/questions/399331/fuse-3d-points-in-bundel-adjustment) I'm actually implementing my own Pose-Estimation/- and -Refinement ...
Is a branched discard to be avoided
When a simulating a camera, I may run into the situation that a black elliptic border is needed (rather than a rectangular image). In this case I have the option to discard the fragment in the ...
