  • Quarantine Engine

    18 enero, 2021 por

    Quarantine Engine is videogame engine that I started to develop during the Covid quarantine in Spain. I started the project in March 2020 and until today, it’s currently being developed and improved. The goal of this project is to continue improving my skills with 3D graphics APIs. It’s currently developed on OpenGL 4.2, although in… Leer más

  • Fast and Cheap Subsurface Scattering

    24 agosto, 2020 por

    Introduction El scattering es un fenómeno que podemos observar en los medios participativos, ejemplos son la piel humana o la leche. Ver Figura 1. En el caso del subsurface scattering, son efectos a escala muy pequeña que otorgan un increíble nivel de realismo a nuestros modelos 3D. El hecho de simular estos efectos en real… Leer más

  • Color Interpolation in Gradient Meshes

    24 octubre, 2019 por

    Introduction Gradient meshes are an industry standard and, therefore, they are found in the specifications of the Adobe PDF format and in the SVG2 open source format. For the color interpolation in a gradient mesh, the orientation of the curves in each node is required, in this way scenes that can become photorealistic are obtained… Leer más

  • Surfaces and Parametric Curves in Vector Graphics

    16 octubre, 2019 por

    Introduction Commonly, when we talk about 2D graphics we mean raster graphics, typical images described with a pixels grid. These kind of images are the best known, but they aren’t the only ones used today. Vector images are also found, which are defined by a set of primitives that can be described as concrete mathematical… Leer más

  • Inverse Distance Weighting

    8 octubre, 2019 por

    Abstract In this post, I want to show you how works the Inverse Distance Weighting (IDW). This color interpolation method is used to visualize elevation, temperature, humidity data, among other examples. The main idea of this deterministic method is compute unknown values with the inteporlation of known values. Interpolation The interpolation is a method that… Leer más

  • A Gaussian Blur Material

    30 septiembre, 2019 por

    Abstract In this post I want to show you how to make a Blurry Water Shader. This is a vertex-fragment shader. And how you can imagine, I use different passes to obtain this effect. Well, It’s not the most efficient shader, but I think that It’s a good example to learn a little about the… Leer más
