Questions tagged [heightmap]

Heightmap is texture containing individual heights used to store terrain data.

Heightmaps textures are used to store geometric detail like terrain, object surface etc. It is used to simplify manipulation of such geometry and even speed up its rendering (if mesh generation moved into shaders).

In case the heightmap is stored in common raster image formats then for proper geometry restoration we need also additional info like: scale,position and orientation for such textures which are not stored in them. So those are usually stored in some separate config file, encoded into filename, or hardcoded into application that uses them.

Draw thick, feathered line with variable thickness in plane C#

I'm creating a heightmap painting tool which uses a spline to paint the heightmap with a value from 0 to 1. The spline consists of several points each of which has different thickness (size/width) and this gets interpolated. The tool paints a…

OpenGL glVertexPointer returning 1281 - Can't figure out why

I have created a class to load Terrain points from a heightmap file; but drawing them causes a crash. I have narrowed down the error to the glVertexPointer() function which returns 1281 (invalid value I am led to believe). I have been through the…

OpenGL: Terrain not drawing (heightmap)

EDIT: I'm thinking the problem might be when I'm loading the vertices and indices. Maybe focus on that section :) I'm trying to load a heightmap from a bmp file and displaying it in OpenGL. As with most things I try, everything compiles and runs…

Heightmap in Shader not working

I'm trying to implement GPU-based geometry clipmapping and have problems to apply a simple heightmap to my terrain. For the heightmap I use a simple texture with the surface format "single". I've taken the texture from Catalinz's XNA blog. What I'm…

How to create a terrain mesh from a heightmap in LibGdx

I am working on a top down game - currently the terrain is a tilemap that is generated based on a heightmap array that holds height values ranging from 0 to 255. I want to change this and instead render a terrain mesh. I understand the basic idea…

SceneKit shader modifier for geometry entry points works in iOS but not OS X

I'm in the early stages of making a SceneKit shader modifier (for the geometry entry point) that displaces a plane's geometry according to a height-map texture. The plan is to use it for creating terrain. In iOS (edit: the iOS Simulator) the shader…

Finding height of point on height map triangles

This question has to exist somewhere, but I'm not sure what it would be called. Following a height map, a terrain exists of right angle triangles. Each point of each triangle takes its height (y) from the height map. If the character is at a…
