Dynamic terrains applying pseudo-infinity and synthesized by Bezier curves

This paper describes the development of a procedural pseudoinfinite deformable terrain system. The proposed method intends to deal with the high performance required by games. In this work the terrains are synthesised using Bezier curves and are loaded and saved automatically as needed, that is according to the camera position. The Heightmap’s generating process is, at some moments of a game, an expensive task. Considering such aspect we perform the Heightmap’s synthesis in the background of the application, restricting it to a specific FPS target. Moreover, we developed a deformation model which allows alterations in the HeightMap and Texture. We have used texture arrays at the GPU level to prevent sending unnecessary data. The performance of the system is measured both in the average FPS during the deformation of the terrain and the time taken for the synthesis
