Language: Spanish
Day: Saturday 8th July
Hour: from 11:00 to 14:00
Requirements: no previous knowledge is required, but it is preferable to be familiar with some programming language. It is necessary to bring a computer.
System requirements:
- Mac 10.11+ / Windows 10 / Linux:
- Intel Core i5 Processor (or faster recommended)
- 4 GB RAM (8 GB or more recommended)
- Google Chrome (or another web browser based on Chromium)
Description
Introductory workshop to the generation of visual images using directly the GPU (graphics target), from the writing of a shader (program) in GLSL, the OpenGL shading language (an interface to communicate with the graphics hardware). In particular, we will use its implementation in javascript (webGL) to be able to use an online text editor.
Tools
Objectives
Acquire basic notions of GLSL.
Understand the advantages and disadvantages of writing programs that work directly with the GPU.
Approve creative coding as a worldly practice.
Create, show and participate.
