RhodiumLC: Pixel Shader GPU Benchmark (OpenGL)

JeGX — Fri, 26 Jan 2018 17:12:59 +0000

Here is a GPU benchmark I created for the review of MSI’s Radeon RX Vega 56 Air Boost graphics card. I wanted a new 100% pixel shader benchmark to compare the raw processing power of recent GPUs. I also wanted to control it via the command line. At the end of 2016 I ported to GeeXLab this shadertoy demo. This demo is perfect: it’s reasonably … Continue reading RhodiumLC: Pixel Shader GPU Benchmark (OpenGL) »

Mesh Voxelization

JeGX — Tue, 31 May 2016 15:51:13 +0000

Voxel, voxelizer, voxelize, voxelized, voxelization… Yesterday I stumbled upon a tweet about a header only mesh voxelizer library in C. This library creates a voxelized mesh from a triangular mesh. It’s really simple to use and I decided to add it to GeeXLab (in v0.12.0.0). This voxelization library does not perform deep voxelization (voxels inside of the mesh), only shell voxelization. But for voxel art, … Continue reading Mesh Voxelization »
