How to develop augmented reality apps with Vuforia for Windows 10

I recently published an article on developing Augmented Reality apps using Vuforia on the Windows Developer blog and thought I’d share it with you. “Augmented Reality is a way to connect virtual objects with the real world, making it possible … Continue reading

4k procedural graphic: Marching Embryos

Just finished a 4k procedural graphic. The image is generated by an executable file with the size of 2.74 kb. The image is generated by raymarching simple distance fields, and perlin noise. Platform: WindowsAPI: OpenGL / GLSLCode: digitalerr0r of Dark … Continue reading

Procedural landscapes using Perlin Noise

A few years ago I read the article “Generating Complex Procedural Terrains Using the GPU” in GPU Gems 3. It covers a way to implement random landscapes using Noise, a great read if you are interested. I’m just in the … Continue reading

XNA Shader Programming – Tutorial 26, Bump Mapping Perlin Noise

This tutorial will continue from Tutorial 25, where we implemented a noise function. Now that you have the Perlin Noise-function in your shader, it is very simple to implement Bump Mapping. The object being rendered contains normals on each point … Continue reading

XNA Shader Programming – Tutorial 25, Perlin Noise using the GPU

This tutorial will intruduce you to procedural textures. If you ever want to generate textures procedurally, you probably stumble upon the Perlin Noise algorithm created by Ken Perlin in 1983. Why noise? If you are trying to model natural textures … Continue reading
