A level of detail method for blocky voxels

Posted on March 3, 2018 by

Large voxel terrains may contain millions of polygons.  Rendering such terrains at a uniform scale is both inefficient and can lead to aliasing of distant objects.  As a result, many game engines choose to implement some form of level of … Continue reading →

Turning 8-Bit Sprites into Printable 3D Models

Posted on September 18, 2012 by

Continuing in the recreational spirit of this blog, this week I want to write about something purely fun.  In particular, I’m going to tell you how to convert retro 16 x 16 sprites into 3D miniatures: This project was motivated … Continue reading →

Simplifying Isosurfaces (Part 2)

Posted on August 20, 2012 by

To briefly recap, our goal is to render large volumetric environments.  For the sake of both efficiency and image quality, we want to introduce some form of level of detail simplification for distant geometry.  Last time, we discussed two general … Continue reading →

Smooth Voxel Terrain (Part 2)

Posted on July 12, 2012 by

Last time we formulated the problem of isosurface extraction and discussed some general approaches at a high level.  Today, we’re going to get very specific and look at meshing in particular. For the sake of concreteness, let us suppose that … Continue reading →
