TERRAGEN 4 FOREST TUTORIAL CODE
Procedural generation only means that code is used to generate the data instead of it being hand made. He has some youtube videos ( great example) of live coding sessions and I can also recommend these. Shadertoy was created by a procedural genius, Inigo Quilez, a product of the demo scene who works at Pixar.
I would recommend you come to it once you've given shader coding a go yourself, as the code there is not for the mathematically squeamish, but that is how procedural content is done. Shadertoy is a superb reference for learning about shader programming. So you'll need to learn about Perlin noise (and its successor Simplex noise). You should also check out WebGL if you want to jump right into writing shaders without having to spend the (considerable) time it takes to setup an OpenGL / DirectX game engine. While my personal preference is for Dx11 / HLSL due to speed, an easier learning curve and Frank D Luna, OpenGL is supported on more platforms. These are languages tied to OpenGL and DirectX respectively. Procedural content generation is now all written for the GPU, so you'll need to know a shader language. SpeedTree is used in movies and architectural presentations.to simulate the growth of blood vessels.simulate the growth of cities in order to plan for traffic management.A good understanding of recursion in any language will strengthen your grasp of Procedural Generation.Īs for 'serious' or non-game code, procedural generation techniques have been used to:
Procedural generation is a technique that can be used in any language (it is definitely not restricted to procedural languages such as C, as it can be used in OO languages such as Java, and Logic languages such as Prolog). Terragen and SpeedTree will show you some amazing possibilities of procedural generation. I used this to get me started with my final year project on procedural generation.įractals are closely related to procedural generation.
You should also learn a little about Perlin Noise if you are interested in generating graphics. You should probably start with a little theory and simple examples such as the midpoint displacement algorithm.
